California heat wave: Hiking caution advised
Southern California is experiencing a record-breaking winter heat wave, with Los Angeles facing potentially dangerous, triple-digit highs [https://latimes.com/california/story/2026-03-11/dangerous-heat-wave-to-scorch-los-angeles-this-week]. Hikers should exercise caution.
The National Weather Service has issued excessive heat warnings for inland areas of Southern California, with temperatures expected to peak on Thursday. Residents are urged to stay hydrated and avoid strenuous activities during the hottest parts of the day. The heat wave is due to a strong high-pressure system over the region, trapping warm air and preventing cooler marine breezes from reaching inland areas. This pattern is consistent with climate change models predicting more frequent and intense heat events. Increased fire risk is a major concern, especially in areas with dry vegetation. Authorities are increasing patrols and urging residents to be extra cautious with potential ignition sources.
