A tornado warning is in effect until 7 p.m. for Harris and Galveston counties.

In addition, Harris County and the surrounding area should expect continued rain this week, with the possibility of low rain totals aggravating flooding from last week's storm.

The region is anticipated to see thunderstorms on and off through Sunday night, according to the National Weather Service. A storm cluster from the medical center down toward northern Brazoria County is expected to cause 1 to 1.5-inch rain totals, and minor flooding on low-lying roads.

The flooding threat is lower during the middle of the week, with a storm system moving across the Great Plains late Tuesday into Wednesday only expected to cause light rain in the Harris County region.

But a storm system approaching from the west next Saturday and Sunday could lead to heavier rain at the end of the week. That storm could aggravate flooding concerns, according to meteorologist Melissa Huffman. It's too early to predict that storm's rain totals, Huffman said.

This week's storms could affect morning commutes in particular.

"There are still roads that are closed, and these may pose problems on the morning commute," Huffman said. "Check for road closures and have alternate routes to drive to work that aren't impacted."
