Harris County Flood Control District Monitoring Heavy Rainfall

The Harris County Flood Control District is actively monitoring heavy rainfall currently over the area. The Flood operations team will monitor rainfall trends and check gages that measure rainfall amounts and water levels in bayous and creeks. The primary threat with this system Friday is street flooding.

The average rainfall expected for Harris County is 3-5 inches widespread today through Sunday with isolated amounts of 6-8 inches possible.  As soils become saturated Friday into the weekend greater amounts of run-off into creeks and bayous will be generated resulting in rises. Harris County residents are urged to monitor weather conditions as well as creek and bayou levels into the weekend. Heavy rainfall could quickly overwhelm storm sewers and roadside ditches resulting in street flooding.

The Flood Control District encourages residents to create an account and sign up for rainfall and water level alerts at FWS Alerts allow residents to customize the sensors they receive alerts from and choose to receive them via text, email, or both.

  • Make sure storm drains and culverts are clear from debris. Clogged drains and culverts can prevent water from traveling to the bayous and tributaries, causing street flooding, and possible house flooding, depending on the amount of rain we receive.
  • In areas that normally experience flooding, move vehicles to driveways or in parking garages as the storm approaches
  • Move emergency supplies and valuables to a high, dry place in your residence.
  • Never drive into high water. Turn Around, Don’t Drown! Less than two feet of water can float and wash away a vehicle. Be especially cautious at underpasses and at night when water across roadways can be difficult to see.
  • Refrain from discarding debris in areas bayous, streams and ditches. Debris should be put in trash bins and then brought inside into garages or backyards, away from drainage ditches and storm sewers.
