Summary-David Zierden Abnormal? dryness (not drought) creeping in to the Southeast and ACF Basin Lawn and Garden index shows moist conditions in Florida, mixed in Alabama and Georgia Overall, the upper and middle ACF basin has seen near normal rainfall at 90 days
Summary-Brian McCallum Realtimestreamflows are in the normal range generally, but drop towards below normal conditions as you move downstream. Inflows into Lake Lanier continue in normal range. Streamflows are at below normal conditions throughout the Flint River basin. Groundwater levels are at above normal levels in South Georgia
Summary-David Zierden Development of El Nino likely? (75%) in the next 1-3 months, likely strength looking less and less El Nino a primary reason for below normal hurricane forecast One-month CPC outlook calls for equal chances, wetter in the Southwest. Not verifying well… Climatologically can expect 5-6” in July, but only 3-5” in August. More for the coastal areas.
Summary-Jeff Dobur 1 Month Streamflow forecast - Near Normal 3 Month Streamflow forecast – Near Normal Not much change from previous forecast
