Arizona – The desert sun turns intense fast this morning, and heat is already building toward dangerous levels across Tucson.
According to the National Weather Service in Tucson, an Extreme Heat Warning remains in effect until 8 p.m., with highs reaching 100°F to 108°F. These temperatures can trigger heat exhaustion quickly, especially under direct sun.
Across Tucson, Oro Valley, and South Tucson, temperatures rise sharply from the 60s this morning into triple digits by mid-afternoon. Pavement heats quickly, and shaded relief becomes limited after noon.
Travel along I-10 and local roadways remains clear, but heat exposure inside vehicles becomes life-threatening within minutes. Never leave children or pets unattended. Plan stops and carry water during any drive.
This early-season heat arrives during peak Spring Break travel, increasing outdoor activity risks. Limit time outside during peak afternoon hours. Shift exercise and errands to early morning or late evening.
The heat lingers into the week ahead. Highs stay near 97°F Monday and Tuesday, then push back toward 99°F by Wednesday. Clear skies and dry air will keep the warming trend steady.
Even nighttime offers limited relief, with lows holding in the upper 50s to low 60s. Homes without cooling will retain heat into the night.
