Watches & Warnings

Heat Advisory
Issued: 3:45 AM EDT Jul. 23, 2016 – National Weather Service

... Heat advisory in effect from noon today to 8 PM EDT this
evening...

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

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

* Impacts... risk of heat-related illness for those without air-
conditioning or those outdoors for an extended period.

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.
