A heat wave gripped large swaths of the Western U.S. on Saturday as temperatures hovered near record highs, heightening wildfire risks in areas that already are dry or burning and prompting warnings for people to stay inside.
A ridge of high pressure is holding heat close to the ground — what’s known as a heat dome — from Arizona to Montana, though the good news is that it will be relatively short-lived, National Weather Service meteorologists said.
Dangerous heat and warnings were plaguing the region, and the National Weather Service on Saturday forecast a number of cities that were expected to hit record highs.
By late afternoon, Las Vegas reached 115 degrees Fahrenheit (46 degrees Celsius), the hottest temperature of the year; that's just one degree off the daily record of 116F (47C).
Phoenix was expected to reach 116F (47C), while El Centro, California, was expected to hit a record 118F (48C).
Even parts of Montana were expected to broil, with a record 104F (40C) forecast for Great Falls.
In Las Vegas, Saturday's high was 10 degrees above normal, with meteorologists warning of dangerous heat through Sunday, when the high is expected to be 114F (45C), said weather service meteorologist Morgan Stessman.
Overnight lows in the upper 80s to low 90s will make the situation especially dangerous because it doesn't allow people’s bodies to recover.
“There's just no relief overnight,” Stessman said.
People were being urged to stay indoors and hydrated.
At the Justa Center in Phoenix, which caters to seniors but opens to the public as a cooling center in the afternoon, the biggest challenge is keeping up with the need for water and electrolytes, said operations director Rudy Soliz.
He said about 200 people come in daily.
“Anybody can come in, get a meal, sign up, get checked in through the cooling center, sit down, relax, watch a little TV, you know, catch themselves before they move on to another cooling center or their destination,” he said.
Several cities nearing record temps
The August record for Las Vegas is 116F (47C), while the hottest on record was 120F (49C) in July 2024, which also was the hottest summer on record, Stessman said.
In Montana, the entire east side of the state was under an extreme heat warning Saturday, though by Sunday, much of the state will be in the 70s, said weather service meteorologist Jeff Kitsmiller.
Still, it’s not as bad as the heat wave in mid-July, when some areas broke all-time records, including Billings, which reached 111F (44C) on July 12, Kitsmiller said.
“That was a rare heat wave,” he said.
“This one fits for this time of year.”
The Montana Rescue Mission, a homeless shelter in Billings, opened its doors earlier than usual on Saturday to provide relief from temperatures.
Dozens of people were expected throughout the day, and the shelter planned to provide dinner, beds and breakfast, a receptionist said.
Great Falls Parks and Recreation's four swimming pools and three splash pads were crowded with people trying to beat the heat, said Katy Houseman, who works at one of the city's recreation centers.
“They’re definitely hitting the pools and doing the splash pads outside and then trying to hide inside where there’s air conditioning,” said Houseman.
“It's super, super hot today.”
Heat is exacerbating wildfire risks
Forecasters were warning that this heat wave, combined with drying from past heat, will add to wildfire risks across the West.
“We’re definitely worried about that” in Montana, where fires already are burning and high winds are forecast for the weekend, said Kitsmiller, adding that most of the state was under a red flag warning.
In Nevada, “with this heat dome setting up, we’ve lost some of the moisture that we did have — like relative humidity in the afternoon bottoming out in the single digits in quite a few places,” Stessman said.
The U.S.
Forest Service has said there is an enhanced wildfire risk through Sunday in most of Southern California except for the coastline.
Extreme heat and drought also have created dangerous wildfire conditions in the Pacific Northwest.
Washington Gov.
Bob Ferguson declared a state of emergency Saturday after unusually high temperatures and high winds exacerbated record wildfires across the state.
He also banned most outdoor and agricultural burning through the end of September.
Ferguson’s proclamation went into effect ahead of an unprecedented “particularly dangerous situation” Red Flag Alert by the National Weather Service, which rated the weather risk as “extreme” across Eastern Washington.
More than 312 square miles (808 square kilometers) are currently burning in 12 large fires.
A red flag alert also was given for eastern Oregon, where crews are battling several large wildfires, including the Rowe Creek Complex fire, which has grown to 490 square miles (1,269 square kilometers) with 57% containment.
Climate change is making heat waves, wildfires more frequent
Climate change from the burning of coal, oil and natural gas is causing larger, more intense and longer-lasting heat waves — which lead to more intense droughts and contribute to larger, more destructive wildfires.
This year’s weather is also expected to be affected by El Nino, a natural warming of the equatorial Pacific that alters weather patterns and spikes temperatures across the globe.
The current El Nino is expected to rank as among the most intense since the weather service began tracking the phenomenon in 1950, experts said.
It's already broken records for intensity at its early stages, United Nations officials warned Friday.
