This is unusual but still dangerous. A severe thunderstorm warning has been issued

[elleng]

for a burst of wind to pass through DC region through around 5:15 pm Friday. There is little rain and no thunder with this, but it's essentially a wall of wind which unleashed 60 mph gusts around Hagerstown and Martinsburg and 71 mph gust in Charles Town, W. Va. Stay inside while this passes.

1. People often lose power when these wind events knock down trees

I lived in Silver Spring when the 2012 Derecho knocked out power for 7 days. People overseas didn't believe such a thing could happen in the US.

2. Right, hard to believe.

Glad I didn't suffer like that, was either in Hagerstown or MoCo or Calvert; guess I should get my calendars organized.
