Dangerous Heat Conditions Expected through Friday
Published on June 30, 2026
The first major heat wave of the summer is upon us, as the National Weather Service has issued a Heat Advisory for today (Tuesday) and an Extreme Heat Warning for Wednesday through Friday.
Dangerously hot conditions with heat index values exceeding 100 degrees are expected. There will be little overnight relief with lows only dropping into the 70s, according to forecasters.
Heat-related illnesses increase significantly during times of extreme heat and high humidity.
“It’s important to be prepared and take the necessary precautions as heat is one of the leading weather-related killers,” said Geoff Dunn, Community Preparedness Coordinator with the Department of Emergency Response. “The most important things you can do are to stay hydrated by drinking plenty of water, stay in an air-conditioned room and out of the sun as much as possible, and check up on relatives and neighbors.”
Take extra precautions if you work or spend time outside and know the signs and symptoms of heat exhaustion and heat stroke. If you can, postpone or reschedule outdoor activities. If outside, wear light-colored loose clothing and a hat.
If you are working outdoors, 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 and call 9-1-1 immediately.
“Young children and infants, the elderly and those with chronic medical conditions are particularly vulnerable to extreme heat,” said Dunn. “Never leave children, seniors, or pets unattended in a car, even for a few minutes.”
