The City of Houston has announced it is activating several preparedness measures as the potential for heavy rainfall and flash flooding continues across the region.

City officials said that Houston Public Works is lowering Lake Houston, placing barricades at flood-prone locations, and preparing dump trucks to assist with potential high-water challenges that may arise.

The Houston Police Department and Houston Fire Department have placed high-water rescue vehicles and boats throughout the city, according to officials.

Officials also said the city's Office of Emergency Management activated the City's Emergency Operations Center at 8 a.m. on Monday to coordinate response efforts and monitor weather conditions.

City leaders warned that during periods of heavy rainfall, some roadways around Houston may temporarily hold water, adding that they are designed to drain quickly to help reduce the risk of structural flooding.

Houston officials advised the public to use patience and caution when travelling through the city, encouraging motorists to slow down, allow extra time to travel, and to never drive through flooded roadways.

"We are taking every step to prepare for this weather and keep our community safe," Houston Mayor John Whitmire said. "I urge residents and visitors alike to stay informed, use caution on the roads, and never drive through flooded streets. By working together and following official guidance, we can help keep everyone safe."
