Rainfall is shifting eastward out of Harris County, but additional heavy rains possible around midday into the afternoon hours.
A National Weather Service Flash Flood Warning is in effect until 10:15 a.m. for Harris, Fort Bend and Wharton County.
With heavy rainfall comes the threat of flooding, so it is important for Harris County residents to be aware of conditions near their workplaces, schools and homes. The Flood Control District urges all residents to monitor rainfall and bayou water levels on its Harris County Regional Flood Warning System website at www.harriscountyfws.org, which includes a mobile application. The District’s Flood Watch team constantly monitors the data and works during severe weather events to advise the public and local officials of areas that are and could be affected by flooding.


REMINDER: Do not drive or walk into high-water areas. If faced with flooding, STAY PUT wherever you are, unless your life is threatened or you are ordered to evacuate.  
Be sure to check out our Flooding Facts and Preparedness section on our website with helpful, printable resources, including a guide on how to create and implement a FAMILY FLOOD PREPAREDNESS PLAN. The Harris County Office of Homeland Security and Emergency Management also has disaster preparedness resources at www.readyharris.org.

Additional flood preparedness tips:

  • Secure valuables and important documents.
  • Avoid driving, if possible. If you must venture out, avoid driving into water of unknown depth. Moving water can quickly sweep you and your vehicle away.
  • Restrict children from playing in flooded areas.
  • Remain in your home during the storm unless instructed to evacuate by local officials.
  • Have a flood insurance policy. For information on flood insurance, visit the National Flood Insurance Program website at http://www.floodsmart.gov or call 1-888-379-9531.
  • Know your home’s risk of flooding. You can view a Flood Insurance Rate Map (FIRM or floodplain map) at the Federal Emergency Management Agency’s Map Service Center (http://www.msc.fema.gov), or refer to the Flood Control District website at http://www.hcfcd.org.
