A severe thunderstorm warning covered southwestern Bexar, southern Medina and northwestern Atascosa counties Friday evening, and a separate flash flood warning took effect for northern Bexar and south-central Comal counties at 9:35 p.m., after 2 to 3 inches of rain had already fallen with another 1 to 2 inches expected. The storms downed trees and power lines across the area. On the North Side, a large tree fell onto an apartment building in the 11200 block of Perrin Beitel near Wurzbach Parkway, forcing residents to evacuate and knocking down power lines at the scene. No injuries or deaths have been reported in connection with the San Antonio storms.
