TS BETA, 2020
  • Dates: Sep 21st – Sep 23rd

  • Duration: 3 days

  • After making landfall near Matagorda Peninsula, Texas, Tropical Storm Beta moved north past Houston. It has caused 13 inches of rainfall in total in the Brays Bayou Watershed over three days.

  • The most intense rainfall occurred on the late night of September 21st and the next morning, with 10 inches of rainfall in 24 hours near Texas Medical Center.

  • Local flooding occurred in many places including Highway 288, causing property damages. The water level in Brays Bayou was close to bank-full, but eventually did not overtop the bank. As a result, no fluvial flooding occurred, and thus large-scale flooding along the Brays Bayou was avoided.
