Summary
Summary

Persistent troughing and slow-moving frontal boundaries have kept the Southeast and ACF basin in a moist pattern during the past two weeks, which has decreased the area of the ACF that is still under drought.

A small area in the northern part of the basin received from 4 to 6 inches during the past 7 days. The rest of the basin received 0.25 to 3 inches.

Streamflowsrecovered sharply in the northern part of the basin, but the southern streamflows are still at or below the historical low observations.


Summary1
Summary

Ground water levels in the southern part of the basin remain near historical low observations.

Reservoir levels have recovered slightly, but remain well below the historical average and mostly within conservation zone 3.

Salinity levels in Apalachicola Bay are near 20 ppt at East Bay Bottom, 22 ppt at Dry Bar, but are about 30 ppt at Cat Point, which is above the level that can injure oysters.


Summary2
Summary

The 5-day precipitation forecast for calls for no rain in the basin.

Sea surface temperatures in the equatorial Pacific Ocean have dropped considerably since late August are now firmly in the Neutral range, which diminshes the likelihood that El Niño will develop.

ENSO Neutral conditions are still more favorable than La Niña for a fall and winter recharge, so the 1-month rainfall outlook calls for slightly above average rainfall in the southern part of the basin and the 3-month outlook calls for above average rainfall throughout the entire basin.


Summary3
Summary

The 1-month streamflow forecast for Lake Lanier inflows has changed to the normal range but all other locations remain below normal.

The 3-month streamflow forecasts show that streamflows are likely to be normal or above normal for Lake Lanier, but for all other locations have the highest probability of below normal streamflows, though the probabilities of normal and above normal streamflows have increased during the past two weeks.
