Heat Advisory
Issued: 3:42 AM EDT Aug. 18, 2017 – National Weather Service

... Heat advisory in effect from 11 am this morning to 8 PM EDT
this evening...

The National Weather Service in Baltimore MD/Washington has
issued a heat advisory, which is in effect from 11 am this
morning to 8 PM EDT this evening.

* Heat index values... around 105 degrees due to temperatures in
the lower 90s and dewpoints in the mid to upper 70s.

* Impacts... the heat and humidity may cause heat stress during
outdoor exertion or extended exposure.

Precautionary/preparedness actions...

A heat advisory means that a period of high temperatures is
expected. The combination of high temperatures and high humidity
will create a situation in which heat illnesses are possible.

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work, the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency - call 911.
