This morning's rain produced a "double rainbow."

Updated 2:48 pm: Parts of Central Texas, including portions of southern Hays County, are now under a Flash Flood Warning. Check this National Weather Service map for up-to-the-minute information on warning zones. 

Earlier: A flash flood watch remains in effect until midnight after storms dropped almost two inches of rain this morning over the Austin metro area, prompting the closure of several low water crossings. Some low water crossings in Hays County were already closed.

"We’ll have a break into the early afternoon and evening hours, then possibly another round [of rain] that will develop tonight," National Weather Service forecaster Aaron Treadwell says. "It’s too early to tell if we’re expecting a flash flood warning."

Rainfall data from the Lower Colorado River Authority shows more than 1.75 inches of rain fell in Dripping Springs today. The downtown Austin area received about 1.5 inches of rain. 

"This is the pre-event here," Treadwell says. "We’re watching a tropical system down by the Yucatán Peninsula, which is still forecast to move up and make landfall around Matagorda Bay and bring us more rain chances Monday and Tuesday."

The National Hurricane Center says an Air Force aircraft will fly close to the system this afternoon to gather more data. 

Meanwhile, this morning's rains produced a "double rainbow" over Austin, and people were sharing it on social media.
