Watches & Warnings

Heat Advisory
Issued: 3:21 AM CDT Aug. 20, 2017 – National Weather Service

... Heat advisory in effect from 11 am this morning to 7 PM CDT
this evening...

The National Weather Service in Memphis has issued a heat
advisory, which is in effect from 11 am this morning to 7 PM CDT
this evening.

* Heat index readings... around 105 degrees.

* Timing... 11 am to 7 PM today.

* Impacts... these conditions will lead to an increased risk of
heat-related illnesses. Heat stroke and dehydration will be
possible for those performing strenuous outdoor activities. The
interior of a vehicle can reach lethal temperatures in a short
period of time.


Precautionary/preparedness actions...

A heat advisory means that a period of hot temperatures is
expected. The combination of hot temperatures and high humidity
will combine to create a situation in which heat illnesses are
possible. Drink plenty of fluids, stay in an air-conditioned
room, stay out of the sun, and check up on relatives and
neighbors.

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 lightweight and loose-fitting clothing when possible
and drink plenty of water.
