The weather service called off its red flag warning, which indicates any wildfires sparked could rapidly spread, as the storm headed eastward.

Countless other bolts flashed between clouds and some areas saw a bit of rain, including San Francisco. The last time it rained there on Sept. 10 was in 1978, the weather service said. Most areas saw minimal rainfall, but others reported measurable rain.
