Bertha's weakening has reduced immediate risks, but residual effects such as swells and dangerous surf conditions are expected to persist along the Louisiana and Texas coasts through Thursday night. The storm may still produce 1 to 3 inches of rain, with isolated amounts up to 4 inches, raising the potential for flash flooding in urban and low-lying areas. Gusty winds, previously recorded at up to 50 mph along the Texas coast, are expected to diminish rapidly as the storm dissipates.
