A strong storm system that unleashed heavy rains across much of Texas will make it way Tuesday night into south Louisiana, which has been upgraded to a "slight risk" for severe weather.

The National Weather Service says severe weather could include thunderstorms, damaging wind gusts, hail and the possibility of isolated tornadoes.

There was an 80 percent to 90 percent chance of showers and thunderstorms for areas from Baton Rouge to New Orleans, ending Wednesday morning.

The same system prompted tornado warnings for dozens of Texas counties, as well as powerful winds. Winds of around 50 mph lashed Corpus Christi and other coastal regions.

More than 3 inches of rain fell in some areas west of Austin.
