Los Angeles, CA – Southern California faces a stretch of dangerous heat starting Sunday, with advisories now in place across Los Angeles, Ventura, Santa Barbara, and San Luis Obispo counties. Highs are expected to climb into the upper 90s and low 100s in valleys and interior mountain areas, while coastal plains could reach the 90s.
According to the National Weather Service in Oxnard, advisories begin Sunday morning for the Santa Lucia Mountains, Santa Ynez Valley, Cuyama Valley, and interior San Luis Obispo County, with heat extending through at least Tuesday evening. Downtown Los Angeles, the San Fernando and San Gabriel valleys, Santa Clarita, and Ventura County valleys fall under a heat advisory from Monday through Tuesday, with the potential for extensions into Wednesday.
Officials warn of a high risk of heat-related illness, especially for the elderly, young children, outdoor workers, and anyone without air conditioning. Overnight lows will remain warm, offering little relief. Residents are urged to limit strenuous activity to morning hours, stay hydrated, and check on neighbors and vulnerable family members.
The heat wave is expected to peak Monday and Tuesday, with advisories possibly extended into midweek if temperatures remain elevated.
