As tropical moisture continues to stream into the region, several rounds of rain, some very heavy at times, will bring at least a 40% chance for flash flooding to a large portion of the western and central combined Panhandles. The heaviest rainfall rates will most likely occur this afternoon through tonight.
Although rounds of rain are expected, some of which will produce moderate to heavy rain, we are anticipating one specific round to potentially produce significant rainfall and higher flash flooding potential. We are expecting this round to begin in the afternoon and last into Tuesday night. However, there is uncertainty regarding where this band of very heavy rain will set up, and this will shift the focus of the greatest rainfall totals and highest risk for flash flooding.
Moderate to heavy rainfall is expected to continue into Wednesday morning with a continued risk for flash flooding. Please be aware of ongoing street ponding or flooding, as well as rising rivers and creeks.
If thunderstorms are able to develop in the far eastern Panhandles Wednesday afternoon, there will be a low chance for a couple strong to severe thunderstorms. The primary hazards will be hail up to the size of quarters and wind gusts up to 60 mph.
Multiple rounds of rain, some of which will produce moderate to heavy rain, is expected through Thursday morning. This is the latest timing.
