The National Weather Service has issued an Extreme Heat Warning across much of Arizona and portions of Southern California, with dangerously high temperatures expected to persist through Tuesday evening in some areas.
In the Phoenix metro area, the warning remains in effect until 8pm MST Tuesday. Afternoon highs across the Valley are forecast to reach between 105 and 110 degrees, posing a major heat risk to residents and anyone spending time outdoors. The warning covers a wide swath of the metro including Central Phoenix, Scottsdale, Paradise Valley, the East Valley, the Northwest Valley, and communities like Chandler, Mesa, Gilbert, Tempe, Goodyear, and Surprise.
Further west, the Parker Valley and Yuma areas are under the same warning from 11am through 8pm MST today, with temperatures expected to climb as high as 112 degrees.
The warning extends into California as well, affecting the Coachella Valley, Imperial Valley, Palo Verde Valley, Chuckwalla Valley, and the San Diego County Deserts, where highs between 103 and 112 are expected through this evening.
Health officials warn that prolonged exposure to these temperatures can rapidly lead to heat cramps, heat exhaustion, and heat stroke. Heat stroke is a life-threatening emergency and requires an immediate call to 911.
The National Weather Service urges anyone working or recreating outdoors to move strenuous activity to early morning or evening hours, wear loose and lightweight clothing, and drink plenty of water. Rest breaks in shaded or air-conditioned spaces are strongly recommended.
Cooling shelters are available throughout the region. Maricopa County residents can call 2-1-1 to locate the nearest cooling center, transportation assistance, and water resources.
