An extreme heat warning remains in effect for Park City and much of northern Utah through early Tuesday

PARK CITY, Utah — Salt Lake City reached 109 degrees Sunday, the highest temperature recorded in the city since official observations began more than 150 years ago, as an intense heat wave continued across Utah.

The temperature at the National Weather Service station near Salt Lake City International Airport reached 109 degrees shortly before 3 p.m. Sunday, breaking the previous all-time record of 107 degrees, according to the National Weather Service Salt Lake City office.

The former record was first set in 1960 and later matched in 2002, 2021, and twice in 2022. Sunday’s temperature also surpassed the daily record of 105 degrees set in 2002, 2003 and 2024.

The Salt Lake Tribune reported that Salt Lake City reached 104 degrees Saturday before temperatures climbed further Sunday. The newspaper also reported that Salt Lake County extended hours at several recreation centers to give residents access to air-conditioned spaces during the heat wave.

Other northern Utah communities also approached or broke records Sunday. A weather station in Logan reached at least 106 degrees, surpassing its previous all-time high of 103 degrees, while Ogden tied its record of 106 degrees, according to the National Weather Service.

The heat has extended into higher-elevation communities. The National Weather Service issued an extreme heat warning for Park City through 6 a.m. Tuesday. Monday’s forecast calls for a high near 85 degrees, with an overnight low around 68. Scattered afternoon thunderstorms could develop Tuesday, when the high is expected to reach about 83 degrees.

The warning covers much of northern Utah, including the Wasatch Front, where temperatures are expected to remain above 100 degrees Monday. Salt Lake City could reach 102 degrees Monday and 101 degrees Tuesday before temperatures begin to moderate later in the week, according to the National Weather Service.

Forecasters said the heat was produced by a strong high-pressure system positioned near the Four Corners region. Warm overnight temperatures have offered little relief, increasing the risk of heat-related illness.

The National Weather Service urged residents to drink plenty of water, avoid prolonged sun exposure, and check on relatives and neighbors. People working or exercising outdoors should take frequent breaks in shaded or air-conditioned areas.

Anyone experiencing heat stroke symptoms should be moved to a cooler location and receive emergency medical assistance, the agency said.
