Subj : Flood Potential AL/FL To : All From : Mike Powell Date : Wed Aug 13 2025 08:03:33 AWUS01 KWNH 131205 FFGMPD FLZ000-ALZ000-131630- Mesoscale Precipitation Discussion 0923 NWS Weather Prediction Center College Park MD 804 AM EDT Wed Aug 13 2025 Areas affected...Southern AL...Western FL Panhandle Concerning...Heavy rainfall...Flash flooding possible Valid 131204Z - 131630Z SUMMARY...Locally concentrated bands of showers and thunderstorms with high rainfall rates will continue this morning across portions of southern AL and the western FL Panhandle. Areas of flash flooding will be possible, and especially for the more urbanized locations. DISCUSSION...The early morning GOES_E IR satellite imagery along with surface observations shows a well-defined low-level vort center and a fairly sharp surface trough advancing east-northeastward to the east of Mobile Bay. This energy continues to foster some deep convection around its southern flank as very moist, convergent and unstable low-level flow advects inland off the nearby Gulf of America and into portions of southern AL and the western FL Panhandle. MLCAPE values of 1500+ J/kg are pooled up across the western FL Panhandle with PWs of 2.25+ inches, and this region in particular will tend to be the primary focus area for additional bands of convection over the next few hours. Rainfall rates up to 2 inches/hour are expected to continue, and some additional storm totals amounts of up to 3 to 5 inches will be possible given localized cell-training concerns with these bands of convection that cross the Gulf Coast and advance inland. Some locations that will likely be impacted by heavy rainfall this morning include the Pensacola to Panama City corridor, and there may be some localized urban flooding concerns that materialize.
