Weather forecast Big Bear Mountain CA

A foreboding weather forecast

A series of El Niño-related rain and snow storms were expected to begin late Sunday night and could last all the way into next weekend.

There's a 30% chance of rain between 10 p.m. Sunday and 4 a.m. Monday, and a 70% chance Monday morning, said Robbie Munroe, a meteorologist with the National Weather Service in Oxnard, with the possibility of up to a half-inch of rain.

The strongest storm of the week is likely to hit Tuesday, Munroe said, bringing 1 to 2 inches of rain in foothill areas and up to 4 inches at higher elevations. Mountain areas above 6, 000 feet could see up to 2 feet of snow.

On Wednesday, another low-pressure system could bring rain that lasts into Friday morning, and next weekend another system is expected to bring rain and snow at higher elevations.

With prolonged rainy conditions ahead, flash floods and debris flows — especially in wildfire burn areas — could endanger communities in the Los Angeles Basin, Munroe said. Heavy snow in mountain areas will make driving dangerous.

The Snow Summit and Bear Mountain ski resorts are operating at capacity, said Clayton Schumacher, marketing director for Big Bear Mountain Resorts. The resorts had a record 17, 000 visitors last week, and dark storm clouds were looming over both resorts Sunday. Snow is forecast for every day next week, Schumacher said.

The storms are among some of the first effects of El Niño, a series of weather conditions caused by warming of the equatorial waters of the Pacific, weakening rains in South Asia and bringing heavier rains to California. The storms peak in January, February and March.

This year's El Niño is expected to be one of the most powerful ever recorded.

None of this week's storms is expected to unleash the sort of intense, short-term precipitation that creates a particularly high risk of mudslides and flash floods. Nevertheless, after lower-than-average rainfall in November and December, the steady torrent should be “a pretty dramatic whiplash, ” said Bill Patzert, a climatologist with NASA's Jet Propulsion Laboratory in La Cañada Flintridge.

Patzert said the wet weather will also be a sobering taste of what is probably in store for the rest of the winter, as weather patterns generated by the El Niño phenomenon aim a stream of heavy storms directly at Southern California through March. “I think this is the beginning of the beginning, ” he said.
