Heat Advisory In Effect As Pasadena Is Forecast To Reach 102

PASADENA, CA — A heat advisory is in effect for the San Gabriel Valley, where temperatures in parts of the valley will reach triple digits Tuesday, according to the National Weather Service.

Pasadena is expected to reach 102 degrees, and Altadena is expected to hit 101 degrees while other parts of the valley will hover in the upper 90s all day. That means temperatures will be hot enough to cause heat- related illnesses. The advisory will be in effect from 10 a.m. to 9 p.m. Tuesday. Overnight low temperatures will be in the mid 60s to near 70 degrees.

"There is an increased risk of heat related illnesses," warned an NWS statement. "The most vulnerable include those involved with outdoor activities, those without access to air conditioning, young children, and the elderly. Temperatures inside vehicles, even if the windows are partially open, can quickly rise to life-threatening levels."
