The local statement from the National Weather Service for Houston read, “A catastrophic and life-threatening flash flooding event is unfolding across Southeast Texas this morning. Many Flash Flood Emergencies have already been issued for the Houston Metro area overnight, some of which remain in effect this morning. Bands of heavy rainfall will continue to drop devastating amounts of ADDITIONAL rainfall across the area over the next several days. Tornadoes have also been occurring across Southeast Texas over the last day or so and will continue through the next several days.”

The statement continues, “Coastal flooding may be an ongoing issue along the coast where winds will continue to push water onshore, particularly south of Sargent. Elevated tides will cause the recession of coastal flood waters to be slow, likely lasting into the first part of the week. Wind gusts to tropical storm force are still ongoing, primarily in the southwestern portions of the area towards Matagorda Bay. Though there are currently multiple hazards present across the area, the greatest threat to life and property remains the ongoing extreme rainfall and subsequent prolonged and catastrophic flash flooding.”
