Copious amounts of tropical moisture still exist across the southern half of Texas. That’s why we’re seeing such widespread showers and storms this afternoon. Several bands of heavy rain are traveling across the state. Check out the radar.

An additional one to two inches of rain is possible so the flash flood watch has been extended until Saturday morning.

Also, we could always use your weather photos. It’s the best way for us to know exactly what you’re looking at in your own backyard. Send them to weather@kxan.com!
