Raindrops won’t fall on State Department heads. (Matt McClain/The Washington Post)

Subscribers to the D.C. government’s Alert DC system, which sends text notices of emergencies and other happenings, got a message today that the State Department would hold an evacuation drill in which employees working in the Truman building headquarters would disperse throughout the Foggy Bottom neighborhood and meet at pre-arranged spots.

Sounds like a prudence exercise, of course, though it really would be very hard on those whose hair frizzes during rain.

Good thing it only would proceed if weather allowed. Real emergencies, however, never seem to have the good sense to hold off in inclement weather.
