Excessive Heat Warning Issued For Thursday

PHOENIX, AZ — It might still be summer, but it's not incredibly common for Phoenix to see 110 degrees this time of year. Expected highs in the Valley Thursday are sultry, between 107-110 degrees, according to the National Weather Service.

Phoenix has reached 110 degrees on or after Sept. 9 only 12 times in recorded history, the weather service said.

An excessive heat warning for Phoenix and the rest of the Valley will take effect at 10 a.m. Thursday and is set to expire at 8 p.m.

An excessive heat warning marks a period of very hot temperatures, even by local standards, the National Weather Service says.

"Don't let your guard down when it comes to protecting yourself from the heat," the National Weather Service said in a Facebook post. "Even though it's September and the sun is less intense, heat illness and death can still occur."

The weather service recommends:

• Drink before you're thirsty
• Reduce time in the sun
• Avoid strenuous activity or postpone it until nighttime
• Seek air conditioning
• Check on the elderly

It doesn't look like the extreme heat is going away anytime soon. The expected highs on Friday and Saturday are 107 and 108 degrees, respectively, and temperatures could reach 110 degrees again both Sunday and Monday, according to the weather service forecast.
