The National Weather Service in Baltimore MD/Washington has
issued a Heat Advisory, which is in effect from noon today to

A Heat Advisory means that a period of high temperatures is

stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

heat should be moved to a cool and shaded location. Heat stroke
is an emergency - call 911.
