Heat Wave, Thunderstorms to Raise the Risk of Wildfires in California

Another heat wave and more monsoonal thunderstorms are expected to increase wildfire danger in California over the weekend and into next week.

A high-pressure system is expected to expand over the western United States on Wednesday and get stronger through Friday, according to the National Weather Service. California will be spared the worst of the heat, the weather service predicted, as the system concentrates over the Rocky Mountains.
