DES MOINES – The active extreme heat warning for our area has been extended through Wednesday night. 

The National Weather Service in Des Moines previously issued an extreme heat warning through Tuesday night for most of the state of Iowa; it is now in effect until 10pm tomorrow evening. The NWS in the Quad Cities also extended its extreme heat warning for southeast Iowa through 10pm tomorrow evening.

Dangerously hot conditions are expected over the course of the warning period, with heat index values above 100 expected, along with nighttime lows not falling below the mid to upper 70s. Extreme heat will persist through much of the week, potentially including the 4th of July weekend.

Officials encourage those in the area to drink plenty of fluids, stay in air-conditioned rooms, stay out of the sun, and check up on relatives and neighbors. Take extra precautions when outside: wear lightweight and loose fitting clothing, and try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke.

Do not leave young children or pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes.
