Storm-Tide Elevations Caused by Hurricane Marilyn on the U.S. Virgin Islands, September 15-16, 1995
By Heriberto Torres-Sierra
Abstract
Hurricane Marilyn impacted the U.S. Virgin Islands with maximum reported winds gusting to near 130 miles per hour from late at night on September 15 to early morning on September 16, 1995. As much as 11.40 inches of rain fell on the island of St. Croix near the airport on September 15. Most of the hurricane damage in the U.S. Virgin Islands resulted from high wind velocities and tidal flooding along coastal areas. At least nine people died and thousands were left homeless as a result of the hurricane. St. Thomas was particularly hard hit; 80 percent of the buildings were damaged or destroyed, six people were killed, and thousands were left homeless.
High-water marks produced by the storm tide from Hurricane Marilyn during September 15-16, 1995, were identified, described, and level- surveyed along the populated coastal areas of Charlotte Amalie in St. Thomas, Cruz Bay and Coral Bay in St. John, Frederiksted and Christiansted in St. Croix, and at other selected areas along the islands' coasts. One hundred seventy-three high-water marks are presented in tabular form listing plate name, mark number, location, latitude, longitude, type and quality of the mark, and high-water mark elevation. Profiles defining the surveyed storm-tide elevation, the inland extent of coastal flooding, and the ground elevation at selected coastal areas are also presented in this report. High-water levels ranged from about 11.4 feet above mean sea level at Estate La Grande Princesse in St. Croix to 3.1 feet above mean sea level at Limestone Bay, Estate Krausses Lagune in St. Croix.
INTRODUCTION
Hurricane Marilyn, a Category 2 hurricane (Saffir-Simpson scale), made landfall on the islands of St. Croix and St. Thomas, U.S. Virgin Islands (USVI) during September 15-16, 1995. The hurricane, with maximum reported winds gusting to near 130 miles per hour, left a path of devastation throughout the islands. This hurricane was one of the most destructive of the nine major hurricanes that have hit the area since the late 1800's (table 1). As much as 11.40 inches of rain fell on St. Croix on September 15. Although some river flooding occurred in low-lying areas near guts (dry stream courses), most of the flooding resulted from tidal flooding along the islands' coasts. The maximum storm-tide elevation measured was 11.4 feet above mean sea level on St. Croix. On St. John and St. Thomas, the maximum storm-tide elevations measured were 11.3 and 10.9 feet above mean sea level, respectively. Damage from Hurricane Marilyn was severe throughout the USVI, particularly on St. Thomas, where about 80 percent of the buildings were damaged or destroyed. Nine people died, several were injured, and thousands were left homeless as a result of the hurricane.
The U.S. Geological Survey (USGS), in cooperation with the Federal Emergency Management Agency (FEMA) and the U.S. Army Corps of Engineers (USAGE), collected data in the USVI on the storm-tide elevations caused by Hurricane Marilyn. This report presents a brief description of the hurricane and its pathway, the effects of the hurricane, the storm-tide elevation data obtained at 173 sites, and a series of maps showing the location and elevation of high-water marks, bench marks, and reference marks. The data presented may be useful for flood-insurance purposes and in guiding future development in these areas.

PATH OF HURRICANE MARILYN
Hurricane Marilyn developed from Tropical Depression 15 that originated over the west-central Atlantic Ocean on September 12 at 6 p.m., Atlantic standard time, about 470 miles east of Barbados (11.9 degrees N. latitude and 52.6 degrees W. longitude; fig. 1). The depression traveled west at about 25 miles per hour (mi/hr) and became Tropical Storm Marilyn on September 13. On September 14 at 2 a.m., Tropical Storm Marilyn, located at about 40 miles east of

Barbados, was upgraded to hurricane status with maximum sustained winds of 75 miles per hour. Marilyn, now a Category 1 hurricane (Saffir-Simpson scale), continued travelling in a west-northwesterly direction with its center passing at about 20 miles northeast of Barbados on September 14 at about 5 a.m. A hurricane watch was issued on September 14 for the USVI at 8 a.m. and then for Puerto Rico at 11 a.m., when the center of Hurricane Marilyn was located about 40 miles east of Martinique. Marilyn, with maximum sustained winds of 80 miles per hour and a minimum barometric pressure of 983 millibars (29.03 inches of mercury) moved in a generally northwesterly direction and passed just northeast of Martinique, making landfall in Dominica at 5 p.m., and then passed to the southwest of Guadeloupe entering the Caribbean Sea (fig. 2). A hurricane warning was issued for the USVI and Puerto Rico when Hurricane Marilyn entered the Caribbean Sea. Hurricane Marilyn continued moving northwest at nearly 15 miles per hour on Friday, September 15, and at 2 a.m. the maximum sustained winds increased to 85 miles per hour and the barometric pressure dropped to 978 millibars (28.88 inches of mercury). On September 15, at 8 a.m. the maximum sustained winds increased to 90 miles per hour and the hurricane was centered about 95 miles east southeast of St. Croix, USVI. By 11 a.m., Hurricane Marilyn's forward motion decreased to 10 miles per hour and the storm strengthened to a Category 2 hurricane with maximum sustained winds of 100 miles per hour and a minimum central pressure of 972 millibars (28.70 inches of mercury). At 5 p.m., when the center of Marilyn was near the southeast coast of St. Croix, an amateur radio operator from St. Croix reported wind gusts of 97 miles per hour. Shortly before 8 p.m., the center of Hurricane Marilyn passed over the eastern portion of St. Croix. A peak gust of 127 miles per hour was reported by an amateur radio operator during the passage of the hurricane. Hurricane Marilyn slowly intensified as it continued moving northwest between 8 to 10 miles per hour. On September 16, between 1 a.m. and 2 a.m., with maximum sustained winds of 105 miles per hour and a barometric pressure of 960 millibars (28.35 inches of mercury), the eye of Hurricane Marilyn extended from the western coast of St. Thomas, USVI to the eastern coast of Puerto Rico's
offshore island of Culebra. On September 16, by 5 a.m. the center of Hurricane Marilyn was located about 45 miles east-northeast of San Juan, Puerto Rico, with sustained winds near 110 miles per hour. By noon, Hurricane Marilyn, with maximum sustained winds of 115 miles per hour (Category 3) and a minimum barometric pressure of 952 millibars (28.11 inches of mercury), was about 70 miles north- northwest of San Juan. At this time Marilyn was moving away from the area and the hurricane warnings for the USVI and Puerto Rico were downgraded to tropical storm warnings. The tropical storm warnings were discontinued for the USVI and Puerto Rico on September 16 at 5 p.m., when the center of Marilyn was about 125 miles north- northwest of San Juan. Over the next 5 days, the hurricane continued its north to northeast movement and lost strength over the open waters of the Atlantic Ocean. By September 21, Marilyn was downgraded to a tropical storm. On September 22, Marilyn was reclassified as an extratropical storm.
EFFECTS OF HURRICANE MARILYN
Rainfall data for the USVI are scarce because many recording rain gages were destroyed or rendered inoperative by strong winds during the passage of the hurricane. The limited rainfall data for the USVI indicate that the south coast of St. Croix, in the vicinity of Alexander Hamilton Airport, received as much as 12.96 inches of rain during September 15-16, 1995 (data were collected at USGS stream and rain gage station 50334500 and are not considered official by the NWS). Approximately 11.40 inches of this total amount fell during September 15. Another USGS rain gage (50252000) in northern St. Thomas, recorded 3.48 inches of rain during September 15 and 5.09 inches of rain during September 16. No data were recovered from recording rain gages on St. John. Although some riverine flooding occurred in areas near guts, most of the flood damage in the USVI occurred in coastal areas and was the result of tidal flooding. High water levels resulting from a combination of normal (predicted) tide, storm surge, and wave action ranged from 11.4 feet above mean sea level at Estate La Grande Princesse, St. Croix to 3.1

feet above mean sea level at Limestone Bay, Estate Krausses Lagune, St. Croix (fig. 3). The elevation of the storm tide at Limestone Bay, St. Croix and at St. Thomas Harbor was also recorded by the National Ocean Service (NOS) tidal gage stations in the USVI (figs. 3 and 4). As shown in figure 4, the high water elevation at the St. Croix tidal gage peaked shortly after midnight and the high water elevation at the St. Thomas gage peaked near 4:00 a.m., Atlantic standard time.
Hurricane Marilyn left a wake of devastation and desolation in its pathway throughout the USVI. At least nine people died and thousands were left homeless as a result of the hurricane. Emergency housing, medical attention, food, and clothing were provided to thousands of people. Damage was extensive and has been estimated by FEMA at about $2 billion (The Daily News, St. Thomas, USVI, October 25, 1995). More than $1 billion of this amount is related to damage sustained by private and public housing. Losses directly related to the tourism industry were estimated at about $475 million.
Damage was more severe on St. Thomas, where about 80 percent of the buildings were damaged or destroyed and thousands of utility poles were downed, leaving the island without power, public-water supply, or communications. The St. Thomas Hospital received extensive damage, particularly in the medical supply warehouse where all supplies were lost or rendered unusable. Hospital patients and people severely injured by Hurricane Marilyn were airlifted by helicopter to a hospital in San Juan, Puerto Rico. The control tower at the Cyril E. King (formerly Harry S. Truman) Airport in St. Thomas was extensively damaged and the runaway was covered with debris, making impossible the arrival of military and emergency flights from the mainland of the United States during the first hours after the passage of the Hurricane Marilyn. The production and distribution of desalinated water was interrupted during several days due to damage to the desalination plant and to two 1- million-gallon water storage tanks. Private cisterns were contaminated by debris, raw sewage and/or sea water from tidal flooding. The sewage treatment plants and pumping stations were also inoperable. A large number of private vehicles and hundreds of boats were
damaged or completely destroyed. All marina and dock facilities were damaged or destroyed by high winds and severe tidal flooding. Coastal flooding occurred in beach and low-lying areas generally where land-surface elevations are less than 8 feet above mean sea level. In some of these areas, sand was transported from the beach and deposited in overwash fans and in other low-lying areas.
Among the areas of St. Thomas most affected by coastal flooding are the Charlotte Amalie Historic District, Frenchtown, and Crown Bay. Private and public housing, hotels, restaurants, stores, and offices within these areas sustained moderate to severe damage. The environmental impact of Hurricane Marilyn was also significant on St. Thomas, where high winds toppled and stripped leaves from trees and bushes, and saltwater burned grass and killed bushes. Six deaths on St. Thomas were directly attributed to the hurricane.
St. Croix and St. John also received substantial storm damage. On St. Croix, the developed coastal areas of Christiansted and Frederiksted were severely affected by high winds and extensive tidal flooding. About 25 percent of the buildings suffered structural damage or were destroyed. Most of the hotels, restaurants, businesses, and private offices in the Christiansted Historic District were affected by coastal flooding. Some schools suffered water damage. All public utility services were disrupted, mainly as a consequence of downed utility poles and wires and damaged or destroyed generators and transformers. The St. Croix Marina was damaged and more than 100 boats were damaged or destroyed along the island's coasts. The manufacturing industry and the agricultural sector were also hard hit by the hurricane. The official death toll from Hurricane Marilyn on St. Croix was reported as two. On St. John, early damage reports estimated that from 25 to 35 percent of all buildings were damaged. Some government buildings sustained major damage. The police station and two clinics were closed due to structural or water damage, or both. The island was left without power when the power supply from St. Thomas to St. John was interrupted by the strong winds. The populated coastal areas of Cruz Bay, on the islands's west coast, and Coral Bay, on the island's east coast, were moderately

affected by coastal flooding. Many boats were damaged or destroyed, particularly those docked in marinas along the southern coast. USVI government officials reported one person killed and three injured during Hurricane Marilyn.
VERTICAL DATUM
The vertical datum used for this study is local mean sea level derived by the U.S. Coastal and Geodetic Survey (USCGS), which is now named the National Ocean Service (NOS). The local mean sea level, which varies with time and distance along the coastline, is the average, over selected time periods, of the midpoints in elevation between mean higher-high water (MHHW) and mean lower-low water (MLLW). The mean tide level (MTL) established by the U.S. Department of Commerce, NOS, is physically the same as the local mean sea level of the USCGS, but is referenced to MLLW datum. That is, the MTL is the elevation of the local mean sea level above the MLLW. The MLLW datum, also called the chart datum, is used by NOS to minimize the reporting of negative values in predicting tide elevations. The entire study area has bench marks established by the NOS, the USAGE, and the USGS based on local mean sea level datum.
STORM-TIDE ELEVATIONS
Immediately after the storm, the USGS sent crews to the coastal regions to determine the maximum water-surface elevations caused by the storm tide. High-water marks were located, identified and tied to mean sea level datum by way of level- surveying. The elevation of each high-water mark was plotted on USAGE maps prepared from aerial photographs (plates 1-16). Discrepancies between adjacent high-water marks result from the effects of wave action, the effects of lag between occurrence of high water outside or both, and the filling of rooms of houses where inside marks were obtained. Further evaluation of local inconsistencies between adjacent elevations of high-water marks is beyond the scope of this study. A description of each mark that included a detailed description of its location, the type of mark (seedline, washline, driftline, or stainline), and an assessment of the quality of the mark was prepared.
The quality of each mark was assigned a category for interpretation of the storm-tide elevation as follows:
* Excellent A level, extremely well-defined line of densely accumulated fine debris (or a distinct stain). Reliable to + 0.05 foot.
* Good A level, well-defined line of densely accumulated fine debris (or a distinct stain). Reliable to ±0.10 foot.
* Fair A level, but less distinct band of fine or coarse debris (or stain). Reliable to within + 0.25 foot.
* Poor A poorly defined band of sparsely accumulated coarse debris that may undulate due to surface wave action. Other examples include a discontinuous scatter of coarse debris on a structure, a coarse ground line of heavy-vegetative drift, or debris hanging in the branches of a tree. Uncertainty in true elevation is greater than about 0.25 foot.
The best high-water marks for determining the maximum still-water storm-tide elevation generally were found inside buildings or other locations where wave action was dampened. Outside marks range from fair to poor quality because of wave action or, in the case of debris lines, distortion by high winds that followed the storm tide. Fifty-three percent of the one hundred seventy-three high-water marks were rated poor, twenty-nine percent were considered fair, ten percent were judged to be excellent, and eight percent good.
After each storm-tide high-water mark was located and assigned a quality rating, the elevation of the mark was determined. Most elevations were determined by using conventional leveling equipment and vertical control stations (bench marks) established by the NOS and the USGS. Descriptions of the high- water marks are given in table 2 (see page 16). Descriptions of the survey marks (reference marks and bench marks) used to determine the elevations of the high-water marks are given in table 3 (see page 23) and are shown on the USAGE maps (plates 1-16, at end of report).
Profiles defining the storm-tide elevation, the inland extent of coastal flooding, and the ground elevation were surveyed at selected coastal areas on each island (fig. 5). In St. Thomas, a profile was

measured in the St. Thomas Harbor area at Charlotte Amalie and in the Crown Bay area. Two profiles were measured in St. John: one in the Cruz Bay area and another in the Coral Bay area. Three profiles were measured in St. Croix: one profile was measured in Frederiksted, one in Christiansted, and one in the Altona Lagoon Beach area. These profiles were surveyed normal to the coastline. The approximate depth of flooding at any point along the inundated area can be estimated by subtracting the ground elevation from the storm-tide elevation. The location of these selected profiles are presented on figure 5.
SUMMARY
During September 15 and 16, 1995, Hurricane Marilyn caused severe damage in the islands of St. Croix and St. Thomas, USVI. The hurricane, with sustained wind speed near 105 miles per hour, left a path of devastation throughout the islands. As much as 11.40 inches of rain fell on St. Croix on September 15. Although some damage resulted from river flooding, most of the hurricane damage in the USVI resulted from high wind velocities and storm-surge flooding along the coastal areas. Damage was more severe on St. Thomas, were about 80 percent of the buildings were damaged or destroyed, six people were killed, and thousands were left homeless.
High-water marks produced by the storm surge from Hurricane Marilyn were identified, described, and level-surveyed along the most affected developed coastal areas. One hundred seventy-three high-water marks are described in this report. High-water marks, as well as survey marks, are plotted on 16 USAGE maps prepared from aerial photographs.
Storm-tide elevations are presented graphically and in tabular form. Elevations of the storm tide above the local mean sea level ranged from about 11.4 feet at Estate La Grande Princesse in St. Croix to 3.1 feet at Limestone Bay, Estate Krausses Lagune in St. Croix.

Appendix 13
APPENDIX 1. HURRICANE CATEGORIES
To relate hurricane intensity to damage potential, the National Hurricane Center uses the Saffir/Simpson scale which assigns storms to five categories. Category 1 is a minimum hurricane; category 5 is the worst case.
floating debris. Low-lying escape routes inland cut by rising water 3 to 5 hours before hurricane center arrives. Evacuation of low-lying residences within several blocks of shoreline possibly required. Practically all poorly constructed sings blown down.
CATEGORY 1 - Sustained winds of 74 to 95 miles per hour and/or storm surge 4 to 5 feet above normal. Low-lying coastal roads inundated. Minor pier damage, some small craft in exposed anchorages torn from moorings. Damage primarily to shrubbery, trees, foliage, and unanchored mobile homes. Some damage to poorly constructed signs.
CATEGORY 2 - Sustained winds of 96 to 110 miles per hour and/or storm surge 6 to 8 feet above normal. Coastal roads and low-lying island areas inundated. Considerable damage to shrubbery and tree foliage; some trees blown down. Major damage to exposed mobile homes and poorly constructed signs. Some damage to roofing materials of buildings: some window and door damage. Considerable damage to piers. Marinas flooded. Small craft in unprotected anchoraged torn from moorings.
CATEGORY 3 - Sustained winds of 111 to 130 miles per hour and/or storm surge 9 to 12 feet above normal. Serious flooding at coast and flat terrain 5 feet or less above sea level flooded inland some miles. Many smaller structures near coast destroyed; larger structures near coast damaged by battering waves and
CATEGORY 4 - Sustained winds 131 to 155 miles per hour and/or storm surge 13 to 18 feet above normal. Flat terrain 10 feet or less above sea level flooded inland some miles. Low-lying escape routes inland cut by rising water 3 to 5 hours before hurricane center arrives. Major damage to lower floors of structures near shore. Major erosion on beaches. Massive evacuation of all residences within 500 yards of shore may be required, and of single-story residences on low ground within 2 miles of shore. Extensive damage to structures. Complete destruction of mobile homes.
CATEGORY 5 - Sustained winds greater than 155 miles per hour and/or storm surge greater than 18 feet above normal. Major damage to lower floors of all structures less than 15 feet above sea level within 500 yards of shore. Low-lying escape routes inland cut by rising water 3 to 5 hours before hurricane center arrives. Massive evacuation of residential areas on low ground within 5 to 10 miles of shore possibly required. Shrubs and trees blown down; considerable damage to roofs of building; and signs down. Some complete building failures.

GLOSSARY
Advisory. A method for disseminating hurricane and storm data to the public every 6 hours. Small craft warnings are released as necessary.
Hurricane Watch. The watch covers a specified area
and indicates that a hurricane may threaten the area,
but is not imminent.
Tropical Disturbance. A moving area of
thunderstorms in the tropics.
Tropical Wave. A westward moving trough of low pressure embedded in the deep easterly current. It tends to organize low level circulation and may travel thousands of miles with little change in shape, sometimes producing significant shower and thundershower activity along its path.
Tropical Depression. An area of low pressure, rotary circulation of clouds and winds to 38 miles per hour.
Tropical Storm. Counterclockwise circulation of clouds and winds 39 to 73 miles per hour. The storm is assigned a name.
Hurricane. When a tropical storm reaches winds of 74 miles per hour or more, it is classified as hurricane.
Hurricane Warning. A hurricane is expected to
strike your area within 24 hours or less with: a)
sustained winds of 74 miles per hour (64 knots) or
higher, and b) dangerously high water or a
combination of dangerously high water and
exceptionally high waves.
Hurricane Center or "Eye". The relatively calm
area near the center of the storm which can last from
several minutes to an hour or more, but it sometimes
ends suddenly as winds return from the opposite direction, often with greater force. Do not go out in the "eye" of the storm as winds can increase to hurricane
force within seconds.
Storm Surge/Tide. The strong winds associated with
Hurricanes and Tropical Storms cause the sea level to
rise above normal tidal heights, with giant wind-
driven waves and strong unpredictable currents, sometimes covering 50 miles.
