AlertHouston – Hurricane Harvey Update #4

The City of Houston is preparing for significant impacts from Hurricane Harvey, currently a Category 4 and expected to make initial landfall between Matagorda Bay and Corpus Christi.  The storm’s current track suggests it will drift back along the coast and make landfall again near Galveston around Tuesday.

Impacts to the City of Houston are expected to mostly be significant rainfall.  The National Weather Service forecast currently indicates that Houston will see close to 20 inches of rainfall over the weekend and into early next week.  This is likely to cause dangerous  flooding throughout the entire Houston region.

Houston is under a:

  • Tropical Storm Warning until further notice
  • Storm Surge Watch until further notice
  • Flash Flood Watch from 4am Friday to 7pm on Tuesday
  • Tornado Watch until 2.00am Saturday

Steer Clear of Flood Prone Roadways
The City of Houston Office of Emergency Management (OEM) is urging residents and visitors to avoid Houston roadways as Hurricane Harvey impacts the area over the next several days.  The Department of Public Works & Engineering and OEM have produced a map of roadway segments and underpasses that are especially prone to flooding.  If residents are unable to suspend all travel during the duration of this storm, they should heed special caution around these locations.

Flood Prone Locations Map

All intersections and underpasses have the potential to be dangerous during periods of heavy and/or prolonged rainfall.  If you see a barricade in your path, DO NOT drive around it or move it.  Barricades are put in place explicitly to protect lives.

Make Preparations Now
