• Spike expected in global temperatures, but the magnitude is alarming.
• Apalachicola River discharges far above normal the last 4 months.
• Big Bend, Northeast Florida, and Southeast Georgia are the “hole” in El Nino rain, heavy amounts in the lower ACF the last 30 days.
• El Nino fading quickly and impacts weakening.
• NOAA predicting a transition to La Nina by fall (70%)

Summary ‐ Paul Ankcorn
• Realtime streamflows are in the normal range for most of the ACF basin.
• 28‐day average streamflows into Lake Lanier are in the normal range.
• 28‐day average streamflows for the Flint River are in the normal range.
• Groundwater levels are in the high to above normal range in Southwest Georgia.

• 1 Month Streamflow forecast ‐ Near Normal
• 3 Month Streamflow forecast – ESP indicates equal chances. Favor near Normal.
• Pie Charts do not directly include any adjustments to the ESP forecast based on ENSO, CPC or other. Based on soil conditions relative to normal in concert with historical precipitation.
