Los Angeles heat wave prompts extreme warnings and rescues
The National Weather Service has issued an extreme heat warning for Los Angeles County and surrounding areas from July 28 to August 2. Forecasts call for valley temperatures of 100‑110 °F, the Antelope Valley and Antelope Valley Foothills could reach 105‑115 °F, and coastal beaches to see highs in the 80‑90 °F range. Ocean water off Hermosa Beach and Zuma Beach is unusually warm at 74 °F and 70 °F, contributing to higher humidity.
Health officials report a rise in emergency‑department visits for heat‑related illness over the past two weeks. Public advisories urge residents to stay hydrated, limit strenuous outdoor activity, and use cooling centers or air‑conditioned spaces. Lifeguards in Los Angeles County performed nearly 2,000 rescues in recent days, including about 1,000 on a single Saturday.
An experiment in the Pacoima neighborhood applied a solar‑reflective pavement coating, DuraShield‑SR, to more than 700,000 sq ft of asphalt. The coating reduced surface temperatures by more than 16 °F and lowered ambient air temperatures by up to 3.4 °F during the heat wave, indicating the potential of cool‑pavement technologies to mitigate urban heat.
