California Dangerous Heatwaves: Heat Dome to Bring Soaring Temperatures, Wildfire Dangers This Early Week

California residents should stay alert to soaring temperatures and potential wildfires this week due to challenging heatwaves and domes. The end of June brought significant weather concerns in parts of the U.S., with scorching heat in parts of California and the southern U.S. The high temperatures can potentially threaten vulnerable populations, including the following:

This summer, it is expected that residents could experience another round of unusual heat. While relief is likely, the return of scorching heat can bring heat-related illnesses. According to a weather report by the NWS Weather Prediction Center on June 30, an excessive heat outlook is likely on the West Coast and parts of interior California on Tuesday. Commuters are advised to check for heat safety and advisories due to possible triple-digit temperatures.

In nearby areas, showers and thunderstorms are likely in the Southwest and Four Corners. Considering the heat outlook in parts of the country, vulnerable populations should keep updated with the latest weather advisories or limit outdoor plans.
