Fires, heat … a hurricane? California’s ‘most unusual’ week of extreme weather

A record heatwave added stress to the electrical grid and made firefighting difficult. Now a hurricane could bring flash floods

A collision of extreme weather events is bearing down on California as wildfires threaten communities, a record-setting heatwave is adding stress to the electrical grid, and moisture from a hurricane is expected to bring thunderstorms and flash floods.

Hurricane Kay, swirling off the coast of Mexico, is on its way north, bringing with it the chance of strong winds, severe rainstorms, and possibly dry lightning that could increase risks for new fire starts. It also could bring some welcome relief to the week of brutally hot weather.
