FIRST ALERT: Excessive heat to last through at least Sunday

TUCSON, AZ (Tucson News Now) -

The KOLD News 13 First Alert Weather Team is tracking unseasonably hot temperatures again this week.

The National Weather Service in Tucson has issued an excessive heat warning through 7 p.m. Sunday, June 25. High temperatures during this time will top out between 108 and 120 degrees, which would put daytime highs within record territory.

The hottest days will likely be through Wednesday, June 21.

We are marking every day through this weekend as First Alert Action Days since we’ll see high temperatures at or above 110 degrees. We typically see our first 110-degree day around June 29. Last year, we hit 110 degrees for the first time on June 4.

Remember, heat is the No. 1 weather-related killer during the summer months in Arizona. Use caution and drink plenty of water and limit your time outdoors during the hours of peak heating.
