Weather Update 9.22.20 - U.S.

Posted by Jarrett on Sep 22, 2020 8:16:59 AM

Tropical Storm Beta made landfall around 10 p.m. CDT last night along the Matagorda Peninsula.  Beta is forecast to move very slowly, or even stall, just inland from the middle Texas coast on Tuesday and Tuesday night, continuing to bring heavy rainfall and flooding to parts of Texas and Louisiana. Meanwhile, Hurricane Teddy will remain in the Atlantic but bring dangerous rip currents, high surf, and swells to much of the East Coast. A low pressure system in the northeastern Pacific will bring rainfall to the Northwest by Wednesday. States with Active Advisories: Texas, Louisiana

While currently stalled just inland of the Texas coast, Beta should begin to move by Wednesday on a more northeastward track near or just inland from the upper Texas coast as it weakens to a tropical depression. Beta should become a remnant low by Thursday as it moves into the lower Mississippi Valley.  Portions of I-45, I-69, and I-610 are closed and/or flooded on the southern side of Houston.
