Snow has already begun to hit the peaks in California and Colorado’s peaks on October 2.

An abrupt change in the weather of Northern California turned into a dusting of snow for the mountain peaks. With snow, flooding, hail, and showers already hitting, more snow and showers are predicted to hit over the course of the next few weeks.

In East Bay, a thunderstorm flooded many of the streets, while Contra Costa County saw a hail storm. Scattered showers throughout the rest of the northern part of the state were common throughout the week. The biggest piece of excitement was the snow on the peaks though. Social media blew up with pictures and exclamations from rock climbers, skiers, and nature enthusiasts who were excited about the start to the season.

Snow will only affect areas 8,000 feet up or higher according to forecasts, and peaks got a dusting of about an inch, says the National Weather Service.

There was also snow seen on the Colorado peaks. It brought in high winds, hail, thunder, and rain, said forecasters, in addition to bringing about three inches of snow to the mountains.

“It should impact quite a bit of the state,” said Frank Cooper, meteorologist for the National Weather Service in Boulder.

Cooper added that the temperatures dropped from 84 degrees to 73 degrees within a day or so, a total of 11 degrees in difference. By the next day, it had dropped an additional five degrees.

Friday night alone saw about one to three inches for the mountain peaks, while was rain in the afternoon, and at night.

“We could get more snow above the timber line,” he said.

Many mark the start of the season by when the snow starts at the peaks, so it looks like this past weekend is it. Many in higher areas may want to start checking up on their snow pushers and getting their homes in order for the chilly months.

“Winter is definitely on the way and we’re fully into our busy season as customers stock up on snow pusher parts and supplies to make their preparations,” says Joe Guerino, Sales Manager, Pro-Tech Manufacturing and Distribution, Inc.“Due to it being an El Nino winter, this year will definitely make the weather more unpredictable than usual.”
