JICA Study on Disaster caused by the Typhoon No. 16 (Ondoy) and No. 17 (Pepeng)
2. HYDROMETEOROLOGY
2.1 Typhoon Tracks
Tropical Storm Ondoy entered the Philippine Area of Responsibility on September 24, 2009. Its entrance enhanced the southwest monsoon and brought rains to the Visayas and Central Luzon area. This caused severe rainfall over Metro Manila wherein normally one month of rain fell in just about six hours triggering knee-deep to roof-deep widespread flooding, power blackout and killing several hundreds of residents in the metropolis.
Just about a week after Ondoy, Tropical Storm Pepeng battered Central and Northern Luzon.
The tracks of these two typhoons are shown in Figure 2.1 and 2.2, respectively.
2.2 Locations of Rainfall and Water Level Stations in Luzon
Rainfall and water level stations for the island of Luzon are shown in Figure 2.3, while those in Metro Manila and along the Laguna Lake are shown in Figure 2.4. The rainfall and water level stations consist of a mixture of those under PAGASA, MMDA, LLDA and DPWH.
2.3 Listing of Rainfall and Water Level Stations in Luzon
Rainfall and water level have been recorded at several of the stations shown in Figures 2.3 and 2.4 where these two tropical storms left their tracks. Considering that most of the populace were caught unaware, only a few persons and agencies were able to partially record rainfall and water level. Only those stations equipped with automatic recorders and telemetering devices were able to fully record the whole event, although total consolidation of the collected data is not fully complete as of this time.
A listing of these rainfall and water level stations for the Island of Luzon is shown in Table 2.1. The list shown thereat includes the name of the station, the organization operating and maintaining these stations, longitude and latitude coordinates, sort of data collected, type of equipment used, data available with respect to the two tropical storms, availability of data and evaluation as to the accuracy of the data collected.
The actual collected data are shown in the attached optical recording file (i.e. DVD).
The hourly rainfall hyetographs and the water level hydrograph are shown in Annex 2 based on the collected data and included in the DVD.
2.4 Laguna Lake Development Authority (LLDA) Data
Water level in the Laguna Lake has also risen as a result of Tropical Storms Ondoy, Pepeng and other subsequent storms. This is shown also in Annex 2 and included in the DVD.
