Watches & Warnings

Excessive Heat Warning
Issued: 12:12 PM EDT Jul. 21, 2017 – National Weather Service

... Excessive heat warning remains in effect until 8 PM EDT this
evening...

* temperatures... maximum temperatures are expected to reach the
middle 90s this afternoon.

* Heat index values... generally from 97 to 103 degrees during the
afternoon and early evening hours.

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

Precautionary/preparedness actions...

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

To reduce your risk during outdoor work the occupational safety
and health administration recommends scheduling frequent rest
breaks in a shaded or air conditioned environment. Anyone overcome
by heat should be moved to a cool shaded location. Heat stroke is
an emergency... call 9 1 1.

An excessive heat warning means that a prolonged period of very
hot temperatures and high humidity will occur. The combination
will create a dangerous situation in which heat related health
problems may develop. Drink plenty of fluids, stay in an air
conditioned environment, stay out of the sun and be sure to check
on elderly relatives and neighbors.

Young children and pets should never be left unattended in a
vehicle under any circumstance. This is especially true during hot
weather when a car's interior can reach lethal temperatures in a
matter of minutes.
