Texas has positioned 1,900 emergency responders across the state ahead of heavy rainfall expected to hit the Katy-Fulshear area through Sunday.

Gov. Greg Abbott announced the deployment Tuesday, Sept. 29, from the state's emergency operations center, warning that moisture from the remnants of Hurricane Polo could bring flooding similar to what parts of Texas experienced in July. NOAA's Weather Prediction Center expanded its level 3 of 4 excessive rainfall risk eastward as of Wednesday, Sept. 30, according to the Houston Chronicle. Flood watches may be issued for counties near and west of the Brazos River.

Most of Southeast Texas, including Fort Bend County, could see 2 to 4 inches of rain through Sunday, according to KHOU 11. The highest totals are expected north and west of Houston. Friday morning carries the best chance for widespread rain, with a 60% chance of showers and thunderstorms.

The state response includes 100 Texas National Guard personnel already deployed, with 400 more on standby. Three Black Hawk helicopters equipped with hoists and rescue swimmers are available, along with 31 military vehicles for high-water rescues. Maj. Gen. Thomas Suelzer, the Guard's commander, said the troops are positioned to protect life and property.

The Texas Department of Transportation (TxDOT) has 1,200 workers and 1,000 pieces of equipment staged for the event. Brandye Hendrickson, TxDOT's executive director for planning and administration, said crews will monitor roadways, check drainage systems, remove debris and conduct damage assessments throughout the storm.

Texas Division of Emergency Management (TDEM) Chief Nim Kidd urged residents to stay off flooded roads.

"We lose too many lives and people trying to drive through low water in their vehicles," Kidd said Tuesday, Sept. 29, as first reported by CW39.

Abbott said the storm's path remains uncertain. If the front stalls, he warned, it could dump far more rain than forecast, particularly along the Interstate 35 corridor. He said residents should expect rivers to rise but acknowledged officials cannot yet predict which ones will flood.

Repeated storms could cause street flooding and raise water levels in creeks and bayous, though they are not expected to exceed their banks, according to the Houston Chronicle. Flooding in underpasses and low water crossings could still be life-threatening.

CenterPoint Energy said it is preparing crews and positioning equipment for possible power outages throughout the weekend.

No flood watch had been issued for Fort Bend County as of Wednesday evening. No local emergency declarations from Fort Bend County, Katy or Fulshear officials had been announced as of Thursday, Oct. 1.
