Alert: Tornado Watch in effect for much of the area until 3 p.m.

HOUSTON – A Tornado Watch is in effect for many counties in the area until 3 p.m.

Those counties include: Austin, Brazoria, Brazos, Burleson, Chambers, Colorado, Fort Bend, Galveston, Grimes, Harris, Houston, Liberty, Madison, Matagorda, Montgomery, Polk, San Jacinto, Trinity, Walker, Waller, Washington, and Wharton.

A Severe Thunderstorm Warning was also issued for Northeastern Fort Bend County, Southeastern Waller County and Central Harris County until 9:45 a.m.

One round of severe storms clipped southeast Texas Saturday afternoon, producing large hail from Houston to Huntsville. A second round of storms will hit the region Sunday morning and early afternoon.. Like Saturday’s storms, Sunday’s storms could produce hail and damaging wind. Isolated tornadoes will be possible, too.

In Southeast Texas, the threat for severe weather will be greatest to the north of I-10. Areas south of I-10 are at risk, too, but the risk is lower because the atmosphere is more stable closer to the coast. Storms will develop along the I-35 corridor and work east during the morning hours. By 10 a.m., storms will be impacting areas north of Houston.

The storms will continue through noon and 1 p.m. before exiting quickly to the east.

As the storms move into Louisiana, they will intensify further. For the second weekend in a row, the deep south -- from Louisiana to Mississippi, Alabama, Georgia and South Carolina -- could face devastating, deadly storms Sunday afternoon and evening. It will be east of Texas where the tornado threat becomes much more substantial.
