Statement as of 11:24 am CDT on July 23, 2016

... Excessive heat warning remains in effect until 7 PM CDT this
evening...

* temperature... high temperatures in the lower 90s combined with
dew points ranging from 75 to 80 will produce heat index
values of 100 to 110 during the peak heating of the day.

* Impacts... excessive heat could lead to severe heat related
illnesses and possibly death if proper action is not taken.

Precautionary/preparedness actions...

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.

Children... seniors and people with chronic conditions are at
higher risk. Reschedule strenuous outdoor activities and exercise
to cooler evening hours. Drink plenty of water and take frequent
breaks to get out of the heat and get into an air conditioned
space. Do not leave pets and/or children in unattended vehicles.
Car interiors can reach lethal temperatures in a matter of
minutes in these conditions.

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. Heat stroke is an emergency... call 9 1 1.
