ACF Climate Conditions and Outlooks
- Florida and the Southeast in the midst of a sharp warming trend over the last 5+ years, especially with nighttime temperatures.
- Record heat in Fall of 2020 and year-to-date for much of Florida, coastal Carolinas
- Abnormally dry conditions persist over eastern Georgia, other patches developing over south Alabama and north Florida
- Some dryness over the middle and lower ACF at 30-60 days, most of the basin above normal at 90 days
- Active pattern to bring more rainfall to the lower ACF in the next couple of days, lesser amounts to the north
- ”La Niña Advisory” now issued by NOAA, 100% chance of continuing through winter
- CPC seasonal forecast favors above normal temperatures and below normal rainfall
- Drought could develop in late winter/spring as the La Niña winter plays out
- Alabama Office of Water Resources states no reported water availability issues, no changes to AL Drought Declaration since 9/1/2020, areas of below normal precipitation since 10/1/2020 in southern 1/3 of AL.
Real-Time Streamflow & Forecasts
- Real-time streamflow in the ACF basin are currently in the high to below normal range.
- The ACF basin is currently ranked as normal flow for the 7-day average streamflow.
- 28-day average streamflow for the Chattahoochee River are currently in the above normal range.
- 28-day average streamflow for the Flint River are currently in the normal to above normal range.
- Real-time groundwater levels across the ACF basin range from much above normal to much below normal, with most stations ranked in the normal range.
- SERFC 10-day streamflow forecast - no large flow events expected
- SERFC 1 month streamflow forecast - near normal
- SERFC 3 month streamflow forecast - near normal
ACF Basin Reservoir Conditions
- Inflows into the projects are normal/above normal.
- Lanier, West Point, and W.F. George are transitioning to winter guide curve elevations, projects are operating slightly above winter pool elevations
- The ACF system conservation storage is in Zone 1 and is forecasted to stay in Zone 1 for the next few weeks.
