Flash flooding is likely with significant street flooding 
The Harris County Flood Control District is actively monitoring the potential for additional heavy rainfall over the area. Currently, Spring Creek, the West Fork of the San Jacinto River and Cedar Bayou are all elevated this morning, but within banks and widespread rainfall of 2-4 inches north of I-10 yesterday afternoon and evening and isolated totals of 5-6 inches over the Huffman and Crosby areas. 
The average rainfall expected for our area is 4-6 inches widespread today through Thursday with higher isolated totals will likely result in street flooding and rapid rises on area bayous and creeks. Some flooding of bayous and creeks will be possible depending on the intensity and longevity of the rainfall.

The flood operations team will monitor rainfall trends and check gages that measure rainfall amounts and water levels in bayous and creeks and coordinate with local, regional, and federal partners on the response and forecast of both heavy rainfall and potential flooding. Rapid rises on area creeks and bayous and the San Jacinto River bason is possible over the next 48 hours. 

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 take the following precautions when heavy rainfall and potential flooding is expected: 
  • Create an account and sign up for rainfall and water level alerts at  fwsalerts.org. 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.
  • Move vehicles to driveways or in parking garages as the storm approaches in areas that normally experience flooding. 
  • 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.
  • View the Harris County Office of Homeland Security and Emergency Management disaster preparedness resources at  readyharris.org.
  • Carry flood insurance. Residents should contact their insurance agent for more information about purchasing flood insurance or visit the National Flood Insurance Program or call 1-888-379-9531. Please keep in mind that new insurance policies take 30 days to go into effect.
