Timing and Overview:

The potential for heavy rain and flooding will continue overnight into early Monday morning. Currently, isolated showers are impacting mainly the Coastal Bend region and may produce moderate to at times brief heavy downpours. Continued redevelopment of showers and isolated thunderstorms over the coastal counties will be possible tonight In addition, a line of thunderstorms is organizing over northern Mexico and will move east overnight into early Monday morning.

These factors combined with the heavy rain that fell earlier today, may lead to flash flooding issues over the Coastal Bend. A flash flood watch will be in effect from 1 AM Monday morning until 11 AM Monday morning. Outside of the flash flood watch area, locally heavy rain may also occur, but confidence was not high enough to issue a flash flood watch for these areas. 

The Monday morning commute across the Coastal Bend may be greatly affected by the heavy rains and possible flash flooding

South Texas Impacts: 

Rainfall: 3 to 6 inches of rain have all ready fallen today across the Coastal Bend. An additional 2 to 3 inches of rain with locally higher amounts appear likely late tonight into Monday morning.

Severe Weather: A few strong storms with gusty winds will be possible, but widespread severe weather is not expected at this time.
