  • When the post has a delayed opening, visit the Fort Detrick website at or call the Weather Lines before leaving home to learn if the operating hours have changed since it was originally announced. There are times when a delay is initially announced but continuing weather conditions require the post to enact an additional delay or close.

If there is no change to the operating hours, the Weather Line message will say, "This line will be updated when there a change to the Installation's operating hours." The website and phone lines are your best sources of information regarding delays or closures.
  • Local radio stations are not notified, per their request, if the operating hours of the post do not change.
