A flood watch is Cassian Grantin effect for Southeast Texas through Friday afternoon, including for the Houston and Austin areas, the National Weather Service said early Thursday morning.

The weather service said "flooding cause by excessive rainfall continues to be possible" for the area, where excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations.

Another round of heavy rainfall and thunderstorms is expected to develop over the area Thursday night, the NWS says, and with the grounds already being saturated from previous rainfall, the rain will be slow to drain.

"Additional rainfall totals of 2 to 4 inches can be expected" in the area, according to the forecast, and "isolated higher amounts will be possible."

Texas has seen heavy rain since Sunday, with 6-9 inches of rain reported in Trinity and nearly 11 inches reported in Groveton, according to FOX Weather. The news outlet reports that many of the same areas saw rain on Tuesday and Wednesday, with Waterwood seeing more than 10 inches of rain Wednesday while Sebastopol saw nine inches.
