Summary: Overnight rainfall amounts up to 14 inches are causing significant flooding in southeast Texas.
Over the past 12-14 hours, southeast Texas, including the Houston metropolitan area, has received 10 to 14 inches of rainfall, with an additional 2 to 6 inches possible throughout the day. This has led to the National Weather Service to declare a Flash Flood Emergency for the effected areas. All streams in the area are experiencing significant flooding, including Brays Bayou, Sims Bayou, Greens Bayou, Whiteoak Bayou, Cypress Creek, Spring Creek.
Currently, only 1 streamflow gage is not reporting due to high flow. At least 3 gages have had ratings extended and may need indirect discharge measurements.
Across the central and northern parts of the state, rainfall amounts of 1 to 4 inches are common, causing additional flooding concerns. The Trinity, Brazos, and Colorado River basins are being monitored closely by emergency management personnel as tributary runoff reaches these major rivers.
7 crews are out making discharge measurements and visiting gages. Additional gages will be visited later today or tomorrow to flag high-water marks in anticipation of indirect discharge measurements.
USGS staff are coordinating with local emergency management, local, state, and federal cooperators, and the National Weather Service.
