Today there's rain, and also tonight there's lightening. Both are rare, the latter moreso.
The rain will quash the fire hazard (typically from Santa Anas, ie Foehn winds, warm dry
winds descending from the deserts down the mountains, say 95F and 20% relative humidity).
It may also cause landslides where its burned, but it didn't burn much this year.

Cool weather is nice, I'm wearing sweatpants instead of shorts for the first time this year.
