A wave of low pressure will move over the southeast region late Sunday through Monday. Widespread rainfall with embedded thunderstorms will bring moderate to heavy rainfall across the local area, with the most intense rainfall expected to begin to affect the Suwanee River Valley and inland southeast Georgia Sunday evening.
This rainfall will gradually shift eastward through Monday morning, with a more robust line of showers and thunderstorms expected to cross the Florida peninsula Monday afternoon. A few strong thunderstorms capable of gusty winds are possible. Rainfall will decrease over the area Monday night through early Tuesday morning. Widespread rainfall amounts of 1-3 inches are possible. Please refer to the attached graphic.
Widespread rainfall amounts of 1-3 inches are expected over the forecast area for this event…with locally higher amounts possible. This amount of rainfall could cause areal flooding problems giving already high moisture content in the soils. A flood watch may be needed for portions of the area, which would likely be issued Sunday, if needed. In addition, this rainfall may cause area river rises later in the week.
A few strong to severe storms will also be possible. The first wave of strong storms could move inland from the Gulf of Mexico Sunday evening which would affect the Suwanee River Valley and portions of inland southeast Georgia west of Waycross. This thunderstorm activity will likely decrease in intensity Sunday night, but locally heavy rainfall will continue. Thunderstorm activity is expected to increase once again Monday as a line of precipitation develops in the Gulf and tracks across the Florida peninsula. As the thunderstorms cross the Florida peninsula Monday, gusty winds will be possible in stronger activity.
