A brief but intense storm brought heavy rain, hail and wind gusts of up to 76 mph throughout the Baltimore region last night, knocking out power to 37,000 homes, authorities reported.
The storm, which lost momentum quickly as it moved south, did not cause major damage or deaths on Maryland roads, although felled trees and power lines blocked some roads, state police said.
Storm spotters in Carroll County reported the wind velocity was strongest there, with gusts of 42 mph and 76 mph between 8 p.m. and 8:30 p.m., the National Weather Service reported. Some small hail accompanied the storm, and about county 10 roads were closed as of about 9 p.m.
As of 10 p.m., lightning and fallen trees had knocked out power lines to about 8,100 homes in Baltimore County; 3,000 in Carroll County; 4,300 in Baltimore City; 1,300 in Anne Arundel County and about 5,400 in Howard County, said Charles Franklin, a Baltimore Gas & Electric Co. spokesman.
Mr. Franklin said that as of 11:15 p.m., power was still out in 23,000 homes and likely would be restored by early today.
The storm brought with it a significant temperature drop on a day that saw sweltering heat throughout the area.
Between 9 p.m. and 10 p.m., the temperature in downtown Baltimore dropped from 92 degrees to 76 degrees.
The storm had passed through the Baltimore area by 10:30 p.m., the weather service said.
