Watches & Warnings

Heat Advisory
Issued: 3:25 PM CDT Jul. 20, 2017 – National Weather Service

... Heat advisory in effect from noon to 8 PM CDT Friday...

The National Weather Service in Sioux Falls has issued a heat
advisory, which is in effect from noon to 8 PM CDT Friday.

* Temperature... high temperatures will reach the mid to upper 90s
Friday afternoon and evening, producing heat index values from
100 to near 110 degrees.


* Impacts... the combination of hot temperatures and high
humidity will increase the potential for heat-related stress
and illness.

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 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.
