Dangerous Heat Persists Across The West

Dangerous heat will continue across much of the West today through Wednesday.

This stubborn weather pattern will cause temperatures to be well above-average from the Desert Southwest all the way to the Canadian border. Afternoon highs are expected to reach 100 to 115 degrees across the Desert Southwest, while many valleys and lower-elevation locations across the Intermountain West climb into the 90s and low 100s. With relatively dry conditions in place, heat index values will generally be close to the actual air temperature.

The West isn't the only location seeing temperatures and heat indices soaring. Temperatures will reach or exceed 100 degrees for much of the southern Plains, with heat indices in this area ranging between 100 and 110 degrees.

Low temperatures in the Southwest will barely escape the 90s, while the south-central U.S. overnight lows will be in middle to upper 70s. Warm low temperatures such as these, when combined with high humidity, can lead to an increased risk of heat-related illness, and could have an impact on power, water, and transportation systems.

Extreme Heat Warnings and Heat Advisories are in effect throughout much of the West.

If you are in one of these areas experiencing extremely hot temperatures, it is exceptionally important to stay hydrated and cool. Avoid exposure to the sun from late morning into the early evening. Make sure to take frequent breaks in the air conditioning or shade, eat and dress lightly, and to use sun protection if outdoors. Always check the back seat before exiting your car, as a vehicle can reach 30 to 40 degrees higher than outdoor temperatures. Never leave kids or pets unattended and remember to “Look Before You Lock!”
