The probability of tropical development associated with the disturbance near the Texas-Mexico border has increased to 60 percent over the next several days.
WHAT:
A Slight Risk to Moderate Risk of excessive rainfall capable of producing flash flooding.
WHEN:
Multiple rounds of showers and thunderstorms are expected each day through the week. The heaviest rainfall is currently forecast to occur on Thursday as an area of low pressure moves across the region.
WHERE:

CONFIDENCE:
Forecasters are confident that multiple rounds of thunderstorms will impact the area and produce periods of heavy rainfall. However, confidence remains lower regarding the exact locations where the most intense storms and highest rainfall totals will occur each day.
Potential Impacts
Widespread rainfall totals of 4 to 6 inches are forecast through Friday.
There is a moderate chance that localized areas could receive 10 inches of rain or more.
Rainfall rates of 2 to 5 inches per hour may occur within stronger thunderstorms, creating a high potential for flash flooding.
As runoff drains into local waterways, flooding concerns may increase along area rivers and low-lying locations.
Residents are encouraged to closely monitor forecasts, remain alert for changing weather conditions, and be prepared to take action should Flash Flood Warnings or additional tropical advisories be issued.
