The National Weather Service has placed Bountiful, Woods Cross, North Salt Lake, and Farmington under a Heat Advisory through Monday night, July 27, as a punishing heat dome parks over the Wasatch Front with no sign of moving.

Daytime highs along the Northern Wasatch Front will hover in the lower 100s through Wednesday, July 29, then climb into the mid-100s Thursday through Sunday, August 2, according to ABC4 Utah meteorologist Noah Price. Those weekend temperatures could challenge existing records for the Salt Lake City area.

Salt Lake City reached 103 degrees on Sunday, July 26, tying a daily record, according to KUTV. Overnight lows barely dipped below 80. That lack of nighttime relief is what makes this stretch especially dangerous.

"The more impactful part of this is the overnight low temperatures, which are really, really struggling to cool off, really at all," NWS Salt Lake City meteorologist Sam Webber told KSL on Sunday, July 26.

Webber said most of the night will be spent in the 80s, with lows only reaching the mid-to-upper 70s just before sunrise. The heat dome, a ridge of high pressure pushing desert Southwest air toward Utah, is expected to remain stationary all week, according to NWS meteorologist Bob Oravec, who spoke to the Associated Press on Sunday.

Wednesday, July 29, is forecast to be the coolest day of the week at 98 to 99 degrees before temperatures surge back above 100 heading into the weekend.

What residents should know

Heat is the deadliest form of weather in the United States, killing more people annually than floods, storms, and lightning combined, according to the National Weather Service.

The NWS advises residents to:

  • Drink water consistently throughout the day, before feeling thirsty
  • Avoid outdoor activity between 10 a.m. and 6 p.m.
  • Check on elderly neighbors, young children, and those with chronic medical conditions
  • Never leave children or pets in a vehicle

Signs of heat stroke include confusion, fainting, hot or red skin, a body temperature of 103 degrees or higher, and a fast pulse. Anyone showing these symptoms should call 911 immediately.

Residents without air conditioning can find cooling center locations by dialing 211, which operates 24 hours a day. Libraries and shopping malls also offer relief during peak heat hours.

The bigger picture

Salt Lake City has already logged nearly 10 days at or above 100 degrees this summer, according to ABC4 Utah. The city set an all-time record of 109 degrees on Sunday, July 12. The forecast projects seven or more additional 100-degree days over the coming week, which would push the 2026 total to roughly 17. The all-time record for most triple-digit days in a single summer is 34, set in 2022.

South Davis Metro Fire and Davis County Emergency Management had not issued public statements specific to this heat event as of Monday, July 27. Residents who need emergency assistance should call 911; for non-emergency heat-related resources, dial 211.
