Harris County officials have issued a voluntary call for evacuation for some subdivisions along the San Jacinto River ahead of anticipated overnight flooding April 30-May 1.

Current situation

Harris County Judge Lina Hidalgo along with the Harris County Office of Emergency Management held a press conference at 7 p.m. April 30 to advise residents in the northeastern portion of the county of the potential for rapid overnight flooding. Per county officials, the east fork of the San Jacinto River will experience a significant overnight surge of 10-15 feet due to heavy rains upstream from this week's storms.

What residents should know

County officials issued a voluntary call for evacuation for the following subdivisions:
  • Idlewild
  • Idle Glen
  • Commons of Lake Houston
Officials noted if residents in the areas are already seeing high water levels near their home, they should not try to evacuate and should instead call 911.

County officials also advised residents of low-lying subdivisions along the river to stay in place until the water recedes, which is expected to take 24-36 hours. Those subdivisions include:
  • Northwood Country Estates
  • River Terrace
  • Cypress Point
  • Kingwood Area
  • Commons of Lake Houston
Additionally, county officials urged motorists to steer clear of FM 1485 and the roads south of FM 1485 due to the likelihood of flooding.

Quote of note

"We are expecting to see levels of street flooding near the river over the next 24 hours similar to what we saw during Tropical Storm Imelda in 2019," Hidalgo said in a statement. "We're already seeing water from the river coming up onto land, and by midnight the neighborhoods near the east fork of the San Jacinto River could see waist-deep or even chest-deep water. If you live in the areas and can evacuate safely, please do so. If you can't, prepare to stay where you are for the next 24-36 hours and do not try to drive through high water."
