Watches & Warnings

Excessive Heat Warning
Issued: 3:15 PM CDT Jul. 22, 2017 – National Weather Service

... Excessive heat warning remains in effect until 7 PM CDT
Sunday...

The National Weather Service in Paducah continues an excessive
heat warning, which is in effect until 7 PM CDT Sunday.

* Timing... through Sunday evening.

* Heat index values... overnight temperatures will only fall into
the upper 70s tonight. Peak heat indices on Sunday will be
around 105 degrees. A chance of thunderstorms and increasing
cloud cover may bring heat index values down Sunday afternoon in
some areas.

* Impacts... the combination of the persistent hot temperatures
and high humidity results in a high risk of heat-related
illness. The very Young, the elderly, those without air
conditioning, and those participating in strenuous outdoor
activities will be the most susceptible. Also, car interiors
will reach lethal temperatures in a matter of minutes.

Precautionary/preparedness actions...

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.

An excessive heat warning means that a prolonged period of
dangerously hot temperatures will occur. The combination of hot
temperatures and high humidity will combine to create a dangerous
situation in which heat illnesses are likely. Drink plenty of
fluids... stay in an air-conditioned room... stay out of the sun...
and check up on relatives and neighbors.
