Heat-Wave Forecast Overview
The National Weather Service (NWS) has issued a high-risk heat advisory stretching from Tuesday through Friday, with an extreme-heat watch continuing through the weekend. Forecasters describe the upcoming period as “very hot or extremely hot,” and expect it to become the hottest week recorded so far in this unusually warm year for the region.
Meteorological Drivers
According to NWS meteorologist Ryan Kittell, the primary cause is a strong high-pressure ridge aloft that produces “compressional warming.” An additional factor is a shift toward more northerly winds, which further elevates temperatures across the inland valleys.
Expected Temperatures and Associated Hazards
Temperatures in downtown Los Angeles already reached 96 °F, and the forecast calls for highs of 96-98 °F through Friday, with valley readings projected between 100 °F and 110 °F. Coastal areas are expected to see highs of 80-90 °F. In Death Valley, the NWS anticipates daytime highs of 119-120 °F and overnight lows in the mid-90s. A recent incident involved a 68-year-old French traveler who died after his vehicle broke down during a 116-°F day in the park, underscoring the danger of extreme heat.
Official Guidance and Public Safety Measures
The NWS urges residents to stay hydrated, remain in air-conditioned spaces when possible, limit sun exposure, and check on vulnerable neighbors. The agency also warns that the current heat advisory could evolve into an extreme-heat warning, which signals imminent danger for the entire population. Kittell notes that historically, such temperature spikes have coincided with large wildfires, adding another layer of risk.
