Missouri City and Stafford residents face a flood threat this week after Gov. Greg Abbott activated state emergency resources ahead of heavy rainfall across Texas.

Abbott directed the Texas Division of Emergency Management (TDEM) to mobilize more than 1,900 responders and 1,500 pieces of equipment statewide, according to the governor's office. The State Operations Center in Austin shifted to around-the-clock operations on Tuesday, Sept. 29. The activation is the second in roughly a week.

The National Weather Service forecast calls for tropical moisture from Hurricane Polo to combine with an approaching low-pressure system, bringing widespread heavy rainfall and thunderstorms beginning in Far West Texas and expanding across the majority of the state by midweek, according to the governor's office.

KHOU 11 meteorologist Chita Craft reported that western Harris County falls under a Level 2 flood threat, with one to two inches of rain expected. Areas east of western Harris County face a Level 1 threat. The sources do not specify a threat level for Fort Bend County by name, but Missouri City straddles both counties.

The heaviest rain is forecast for Thursday and Friday, according to FOX 26 Houston. Southeast Texas faces a 2-out-of-4 flood risk on Thursday. Polo weakened from a Category 5 storm to a Category 3 before reaching Baja California.

"There is still time for Texans to be able to take action ahead of this heavy rain hitting your region," Abbott said at a Sept. 28 briefing in Austin, as reported by Houston Public Media.

TDEM Chief Nim Kidd said at the same briefing that heavy rain will hit some areas hard. Brandye Hendrickson, a deputy executive director with the Texas Department of Transportation, noted that just six inches of fast-moving water can cause drivers to lose control.

Missouri City has recent experience with flash flooding. On July 23, portions of the city received more than 5 inches of rain in two hours, causing street ponding, flooded underpasses and road closures.

State resources on standby include Texas A&M Task Force 1 swiftwater rescue boats, Texas National Guard personnel with Blackhawk helicopters, Texas Parks and Wildlife Department game wardens with rescue boats, and Department of Public Safety (DPS) troopers and marine units.

As of Sept. 26, no statement from Fort Bend County's Office of Homeland Security and Emergency Management, Missouri City Emergency Management or Stafford officials had addressed this week's flood forecast. Fort Bend County Judge Daniel Wong urged residents on Sept. 2, during Tropical Storm Edouard, to sign up for the FBC Alert system by texting "FBCAlert" to 888777.

Fort Bend County Commissioners Court approved funding Sept. 24 for a new real-time flood dashboard that will help the county's Drainage District respond faster during emergencies.
