Heat advisory to cover northeast Colorado through Monday
A National Weather Service advisory is scheduled from noon Sunday through 9 p.m. Monday, with temperatures reaching 98 to 104 degrees Sunday and 96 to 101 Monday.
A National Weather Service Heat Advisory is scheduled from noon MDT Sunday, Aug. 2, through 9 p.m. MDT Monday, Aug. 3, across much of northeast Colorado. The advisory warns that the heat could cause heat-related illness.
The NWS Denver/Boulder bulletin includes parts of Larimer, Weld, Boulder, Jefferson, Broomfield, Douglas, Denver, Adams, Arapahoe and Elbert counties, with elevations varying by zone. It forecasts temperatures from 98 to 104 degrees Sunday and 96 to 101 Monday.
NWS point forecasts called for a high near 101 degrees in Denver on Sunday, with a low near 70 Sunday night. Boulder’s forecast also called for a high near 101 and a nighttime low near 70. Those point forecasts are representative and do not establish conditions across every advisory zone.
As of Sunday morning, the advisory had not begun, and no post-event observations or summary were available. Denver International Airport reached 103 degrees Sunday, July 26, breaking the daily record of 100 set in 1910, according to NWS Denver/Boulder climate records.
Stay safe in the heat
NWS guidance recommends drinking fluids, staying in air conditioning or shade, wearing lightweight, loose-fitting clothing and limiting strenuous activity during the hottest part of the day. Check on older adults, young children, pregnant people and anyone with medical conditions, particularly those without air conditioning. Never leave a child, disabled person or pet in a vehicle.
Colorado’s government portal directs residents to call 211 for assistance and referrals. People seeking a cooling center should call 211 or check with their county or city before traveling; no single statewide, live cooling-center list was identified for this update.
Heavy sweating, weakness, dizziness and muscle cramps can signal heat exhaustion. Confusion, unconsciousness or very high body temperature can indicate heat stroke. CDC guidance says to call 911, move the person to a cool area and use cold, wet cloths or ice packs while waiting for help if heat stroke is suspected.
