With Phoenix temperatures climbing, another heat warning issued

PHOENIX – With temperatures expected to climb above 110 degrees, an excessive heat warning is being issued for metro Phoenix for the second time in under a week.

The National Weather Service warning, which alerts residents to an increased risk of heat-related illness, was set for 10 a.m. Tuesday to 8 p.m. Thursday.

“It’s definitely a pretty significant event,” Marvin Percha of the National Weather Service in Phoenix told KTAR News 92.3 FM on Tuesday.

The Phoenix forecast calls for a high of 108 degrees Tuesday followed by a pair of serious scorchers: 111 on Wednesday and 112 on Thursday.

That’s not quite record territory, but it’s more than 10 degrees above normal for this time of year. It could be even hotter in other areas of Maricopa County.

Warning signs of heat-related illnesses can include heavy sweating, muscle cramps, weakness, headache and nausea.

Too much time in the sun can lead to heat exhaustion, heat stroke and death.

“The best thing to do is make sure you restrict your outdoor activities, if at all possible, to … the late evening or early morning hours, and also to take breaks, remain well hydrated and also spend as much time as you can in air-conditioned cooler places,” Percha said.

Be aware that a statewide curfew is in effect from 8 p.m. to 5 a.m. nightly until Monday morning.

You can also mitigate the heat by wearing a wide-brimmed hat to cover the face and neck. Long sleeves and loose-fitting clothing can help keep you cool and protect your skin from the sun.

It’s so hot in Phoenix that a temperature record was broken Tuesday before most people even woke up.

The overnight low was 87 degrees, 5 degrees higher than the previous maximum low temperature and 13 degrees hotter than the normal low, authorities said.
