Phoenix, AZ – Hazy skies and unhealthy air quality are expected to linger over the Valley for the next several days as wildfire smoke from California mixes with clouds, reducing visibility and trapping pollutants. The Arizona Department of Environmental Quality warns that residents should limit outdoor activity, especially during the hottest hours of the day.
Hazy Skies and Poor Air Quality
The smoke, carried into Arizona by a shift in the upper-level wind pattern, is not from local fires but from ongoing wildfires in California, according to Arizona weather officials. The combination of clouds and smoke has led to reduced visibility and a decline in air quality across Phoenix and surrounding areas.
Tonight’s Forecast
Showers and thunderstorms are moving southeast across mountain terrain, with rain expected to end overnight. The northeast Valley may still see a light shower this evening, and there’s a slight chance for rain in the Valley on Monday morning. Overnight temperatures will fall into the upper 80s.
Heat Warnings in Effect
Monday will bring extreme heat with highs near 110°F in the Valley. An Excessive Heat Warning remains in effect until 8 p.m. Tuesday. Temperatures will stay around 110 degrees for much of the week, with mostly sunny yet hazy skies. Isolated showers and thunderstorms are possible in Rim Country and the White Mountains during the afternoon. The Valley’s best chances for rain will come Thursday through Saturday.
Understanding Heat Emergencies
Heat-related illnesses range from heat cramps to heat stroke, the latter being a life-threatening emergency. Symptoms of heat stroke include an elevated temperature above 103°F, confusion, rapid pulse, seizures, and unconsciousness.
What to Do During a Heat Emergency
If someone is experiencing heat-related symptoms:
- Move them to shade or a cool location
- Apply cool, wet cloths to the neck, groin, armpits, and head
- Fan the body and offer sips of cool water if the person is alert
- Massage cramped muscles until relaxed
- Call 911 if symptoms worsen or the person becomes unconscious
Avoid giving anything by mouth if the person is vomiting or unable to swallow. Never underestimate the severity of a heat emergency.
Prevention Tips for Hiking or Exercising in Heat
- Hydrate before, during, and after activity
- Wear light-colored, lightweight clothing and a hat
- Carry a cell phone and hike with company
- Inform someone of your plans and expected return time
The Arizona Department of Health Services also advises residents to stay in air-conditioned spaces, use cooling centers, limit outdoor activity during midday, check on at-risk individuals twice daily, and monitor both the UV Index and the heat risk map.
