Excessive Heat Warning
Issued: 3:32 PM CDT Jul. 16, 2019 – National Weather Service

... Excessive heat warning in effect from 1 PM Wednesday to 8 PM
CDT Saturday...

The National Weather Service in St Louis has issued an excessive
heat warning, which is in effect from 1 PM Wednesday to 8 PM CDT
Saturday. The excessive heat watch is no longer in effect.

* Heat index values... up to 113 due to temperatures in the upper
90s, and dewpoints in the lower 70s.

* Timing... beginning Wednesday afternoon and continuing through
early Saturday evening.

* Temperature... highs each afternoon will be in the mid to upper
90s.

* Impacts... dangerously high temperatures and humidity could
quickly cause heat stress or heat stroke if precautions are
not taken. The very Young, the elderly, those without air
conditioning, and those participating in strenuous outdoor
activities will be the most susceptible. Also, car interiors
can reach lethal temperatures in a matter of minutes.

Precautionary/preparedness actions...

An excessive heat warning means that a prolonged period of
dangerously hot temperatures and high humidity will occur. In
addition, nighttime conditions will remain warm and muggy
providing little chance for relief. This combination will create
a dangerous situation in which heat-related illnesses are likely,
especially for those living in un-air conditioned homes or
apartments. People in the warning area are advised to avoid
poorly ventilated areas and prolonged work in the sun. Use air
conditioning in your house or apartment if it is working
correctly. If you do not have air conditioning, keep your house
or apartment well ventilated with fans, and try to spend some
time in an air conditioned environment to give your body a break
from the heat.

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to the 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 9-1-1 immediately.

Where's baby? Look before you lock! Young children and pets
should never be left unattended in vehicles under any
circumstances. This is especially true during warm or hot weather
when car interiors can reach lethal temperatures in a matter of
minutes.
