Heat Safety Tips

Dangerously hot temperatures are expected across the region today, with possible record breaking heat. Today's forecasted high temperatures range from 112-120° across the lower deserts and range from 100-110° across the higher terrain.

Increasing high pressure over much of the western states will lead to well above normal temperatures and excessive heat. Highs in the lower deserts of Arizona and southeast California will range from 112-120 today through at least Tuesday.

Well above normal temperatures will continue through the next 6 days as very strong high pressure builds over the region. Lower desert high temperatures will reach 112 - 120 degrees through at least Tuesday.

An Excessive Heat Warning is in effect through Tuesday, July 9 for the Arizona lower deserts and southeast CA as high temperatures will range between 112-120 degrees with overnight/early morning lows ranging from the low 80s to low 90s.

The lower deserts will see widespread Major HeatRisk with localized Extreme HeatRisk. For the higher terrain areas, despite the HeatRisk category not being at the Major or Extreme level, the heat is still dangerous. Remember to keep practicing smart heat safety, such as drinking plenty of water and limiting your time outdoors.
