Tropical Storm Beta

Tropical Depression #22 formed across the Southwestern Gulf of Mexico late on September 17th, and intensified into Tropical Storm Beta by the afternoon of the 18th. Beta continued to intensify overnight as it moved northward, reaching its maximum intensity of 60 mph the morning of the 19th. Beta slowed considerably, gradually turning to the northwest towards the Texas coast. Beta slowly weakened as it approached the Texas coast, eventually making landfall as a minimal tropical storm across the southern end of Matagorda Peninsula around 10 PM CDT on September 21st.

Beta further weakened to a tropical depression after landfall, and eventually a post tropical cyclone as it moved northeast across the remainder of Southeast Texas and Central Louisiana September 22nd through the 23rd.

For our region, minimal sustained tropical storm force winds were recorded during the afternoon and evening hours of September 21st across the coastal parishes of Southern Louisiana, coastal counties of Southeast Texas and adjacent coastal waters.

Coastal tides between 3.00-3.25 feet Mean Higher High Water (MHHW), or a rough estimate of the level above ground level, were recorded across the Southeast Texas and Southwest Louisiana coastline, aggravating the recovery efforts after Hurricane Laura. Further east across the Southcentral Louisiana coast, tides ranged from 2.50-3.00 Mean Higher High Water (MHHW).

A brief episode of severe thunderstorms accompanied the passage of post tropical cyclone Beta during the afternoon of September 23rd across Central Louisiana, with a few severe and tornado warnings issued. However, no reports of damage were received.
