The National Weather Service has issued a heat advisory for the Western and Eastern San Fernando Valley regions of Southern California, warning of dangerously high temperatures on Sunday between 10 a.m. and 6 p.m. The advisory signals that conditions could pose a genuine risk to human health, particularly for vulnerable populations.

Why it matters

Heat advisories are issued when temperatures are expected to be uncomfortable enough to potentially cause heat-related illnesses like heat exhaustion and heat stroke, which can be medical emergencies. The San Fernando Valley is known for its hot, dry climate, and the advisory aims to raise awareness and encourage residents to take steps to stay safe during the peak heat hours.

The details

The heat advisory covers the Western and Eastern San Fernando Valley regions. During the 10 a.m. to 6 p.m. window, the combination of direct sun exposure, elevated air temperatures, and limited shade in certain outdoor areas can create conditions that push the body toward heat exhaustion or heat stroke. Heat exhaustion typically presents with heavy sweating, weakness, a fast but weak pulse, nausea and cool and pale skin, while heat stroke is more severe with a high body temperature, hot and red skin, a rapid and strong pulse and potential loss of consciousness.

• The heat advisory is in effect from 10 a.m. to 6 p.m. on Sunday, March 8, 2026.

What’s next

Residents are encouraged to check with their city or county for information on local cooling centers that may be available during the advisory.
