Millions of residents across five states are being warned to avoid prolonged sun exposure as extreme heat sweeps across parts of the western United States.
The National Weather Service (NWS) has issued multiple Extreme Heat Warnings covering areas in Washington, Oregon, California, Arizona, and Nevada, with dangerously high temperatures expected through the weekend and into early next week.
Why It Matters
Extreme heat poses a serious health risk, particularly for vulnerable populations such as young children, the elderly, and those with preexisting health conditions. High daytime temperatures combined with limited overnight relief can lead to heat exhaustion, heat stroke, and other heat-related illnesses, which can be life-threatening without prompt intervention.
What To Know
In the Seattle area, including Mercer Island, Redmond, Tacoma, and surrounding regions, temperatures are predicted to reach the upper 80s to mid-90s, with overnight lows in the mid-60s, creating a major risk of heat-related illnesses. The warning remains in effect until 5 a.m. Tuesday. Forecasters advise residents to drink plenty of fluids, stay in air-conditioned spaces, and avoid leaving children or pets unattended in vehicles.
Extreme heat is also affecting Southern California’s Coachella Valley and San Diego County deserts, where temperatures could soar to 112 degrees. In Arizona, areas including Tucson and the Phoenix metro are experiencing highs between 102 and 112 degrees, prompting authorities to remind residents to take precautions during outdoor activities.
“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!” the NWS said.
In Nevada, temperatures in Las Vegas and Death Valley could climb as high as 120 degrees at Furnace Creek, with minimal overnight relief expected.
The warnings extend to parts of Oregon and other parts of Washington, including the Portland-Vancouver metro area, the Columbia River Gorge, and valleys across central and southern Oregon. Temperatures are predicted to reach 97-103 degrees with overnight lows between 60 and 70 degrees, placing residents at elevated risk for heat exhaustion and heat stroke.
Officials are urging people to take extra precautions when working outdoors, wear lightweight clothing, and check on neighbors and vulnerable populations. Public cooling shelters are available in some areas in Arizona, and residents are encouraged to contact local resources such as 2-1-1 for guidance.
What People Are Saying
NWS Seattle said on X: “Well above normal temperatures are expected through next week. We’re looking at widespread moderate/major HeatRisk levels which means that we’re particularly concerned about those that are sensitive to heat and/or those without adequate access to effective cooling or hydration.”
NWS San Diego said on X: “Heat and chances for T-storms going into the weekend. Protect yourself from the heat while spending time outside, stay hydrated & take breaks in the shade. REMEMBER If you hear thunder, you are close enough to be struck by lightning. When Thunder Roars, Go Indoors!”
NWS Tucson said on X: “A few strong thunderstorms are possible this afternoon into early this evening across central & western Pima county where deeper moisture will reside. Highs similar to previous days with Extreme Heat Warning in effect today for eastern Pima county & southeast Pinal county.”
What Happens Next
The weather warnings are in place between Saturday and Wednesday.
