“The 2 occasions in and of themselves aren't terribly uncommon,” he mentioned. “Whereas the magnitude” of the warmth wave “was increased than what we normally see,” it was common.”Likewise,” Behringer added, “with the rain, to see some rain in September is just not unusual,” however “to see the extremes like we did makes it uncommon. We set all-time data with the warmth, and now we’re getting double the month-to-month precipitation.”
The rising probability of rain Sunday for northern and central California begs the query "Is that this uncommon?" And the reply is "NOT REALLY"! Up to now 173 years, there was rain in San Francisco in 111 years (64%) with 1 / 4 inch 27% of the time. pic.twitter.com/lTPYhBxL3V

Some crews already battling the brutality of fireplace season — resembling these at present preventing the Mosquito Fireplace in Placer and El Dorado counties — noticed the rain assist elevate containment ranges over the weekend.
