Flooding is possible in South Texas as we head into July 4th. Here's where.

SAN ANTONIO — IMPACT DAYS:  Thursday, July 3 and the morning of Friday, July 4

Reason: Potential for locally heavy downpours, especially in the Hill Country and counties west of San Antonio.

A Flood Watch was issued by the National Weather Service for parts of the Hill Country and other counties west of San Antonio in anticipation of isolated heavy rainfall that could causing flooding hazards. 

The watch is in effect for Val Verde, Edwards, Real, Kerr, Bandera, Kinney, Uvalde and Medina counties until 7 a.m. on on Friday–the Fourth of July, when millions of drivers are expected to hit the roads, per AAA Texas. Isolated rainfall amounts of up to 7 inches are possible in some communities, and rivers, creeks and streams could overflow. 

The NWS says thunderstorms may produce heavy rain and gusty wind at times. 

The communities under the Flood Watch face a Level 2 out of 4 risk for excessive rainfall resulting in flash flooding. San Antonio is just out of that area, and instead was assigned a Level 1 risk, though downpours in the Alamo City shouldn’t be ruled out either. 

There is a chance for scattered rain over the next several days, including early on July the Fourth. It should be partly cloudy with a temps in the upper to mid-80s at 9 p.m. for fireworks shows on the holiday. 

A Flood Watch is issued when flooding is possible. It’s different from a Flood Warning, which NWS issues when hazardous flooding is actively happening.
