The first day of summer is forecast to bring some of the worst heat the southwestern U.S. has seen in years.

Extreme Heat Wave

Jun 19, 2017

An extreme heat wave will impact Arizona, as well as much of the West through the week. What makes this unusual compared to our typical summer heat is the extended period of days it will last and temperatures will approach all-time record numbers for many locations. 

The NWS has issued Excessive Heat Warnings and Heat Advisories for the entire region. Heat of this magnitude can pose dangers of heat related illness. Please remember to drink plenty of water and try and keep yourself, family members and pets cool.
