Southern California Endures Record Heat Wave Amid Remnants of Tropical Storm Elida

A prolonged heat wave is gripping Southern California, with forecasts of triple‑digit temperatures (up to 108 °F) and unusually warm overnight lows. The National Weather Service has issued heat advisories and extreme‑heat warnings covering the Los Angeles valleys, San Fernando and San Gabriel valleys, Antelope Valley, and surrounding mountain areas, effective through late July. Officials warned of heightened risk of heat‑related illness, especially for vulnerable groups, and urged residents to stay hydrated, seek air‑conditioned shelter, and check on neighbors.

The heat surge is compounded by the remnants of Tropical Storm Elida, which, while weakening, has generated strong onshore winds, elevated humidity, and dangerous surf along the coast. In Northern California, red‑flag warnings were posted for parts of Siskiyou, Humboldt and Trinity counties because the same system raises fire‑weather concerns. Fire officials highlighted the danger of rapid vegetation ignition under the dry, windy conditions.

The advisory period runs from July 21 to July 27, with the peak expected on Thursday. While temperatures are not projected to break all‑time records, several locales (Woodland Hills, Van Nuys, Palmdale) could approach historic daily highs. The combined heat and fire risk prompted multiple agencies to issue public safety alerts across the region.
