11:40 a.m.: Delays and cancellations at LAX

Airlines are reporting six cancellations and more than 90 delays at LAX, the airport said. 

Some international airlines have been manually checking in passengers since they are unable to process passengers electronically.

According to LAX, significant damage to any of its facilities has not been reported. But FedEx has said that heavy winds has blown loose some of the roof shingles on its hanger rooftop. 

Airport officials said that they're expecting operations to return to normal this morning.

8:21 a.m.: Storm temporarily knocks out power at Los Angeles airport

Some flights are delayed after a powerful thunderstorm briefly knocked out power in all terminals at Los Angeles International Airport.

LAX spokeswoman Nancy Castles says backup systems kicked in after electricity was lost around 6 a.m. Monday.

She says heavy lightning was spotted as the storm cell passed over the airport west of downtown Los Angeles. Power was restored in all terminals within about an hour.

Castles says two flights were diverted to LA-Ontario International Airport in inland Southern California.

Some arriving and departing flights are delayed, but no cancelations are reported.

The fast-moving storm is making for a difficult commute across the region.

Flash flood watches are in place for some areas.

The storm rumbling across California dumped nearly 3 feet of snow in parts of the Sierra Nevada overnight.

National Weather Service meteorologist Brian O'Hara said early Monday that Sugar Bowl ski resort saw 33 inches of snow overnight at the summit while Northstar logged about 10 inches overnight. O'Hara says Mammoth Mountain recorded just 4 inches overnight but the resort is expected to see more snow Monday as the storm moves south.

The California Highway Patrol said flooding was reported on roadways in the San Francisco Bay Area with some areas under more than a foot of water during the Monday morning commute. Santa Cruz and Santa Clara counties saw about 11 inches of rain each over 72 hours.

The CHP issued a wind advisory for the San Francisco Bay Bridge where gusts were recorded at 50 mph.

Forecasters say another round of heavy rain is set to hit the region in the second half of this week.

7:01 a.m.: California storm moves south with pounding rain

A massive winter storm that walloped the Sierra Nevada with blizzard conditions is bringing powerful thunderstorms and dangerous surf to Southern California.

The National Weather Service is warning of possible flooding Monday as heavy rains along with thunder and lightning move through the greater Los Angeles area.

Flash flood watches are in place for foothill neighborhoods underneath wildfire burn areas, triggering fears of possible mudslides.

Snow was expected at the 5,000-foot level in mountains in Los Angeles and San Bernardino counties.

Up to two inches of snow per hour was predicted overnight for the Sierra Nevada, where drivers were warned of whiteout conditions.

Caltrans crews shut a section of Interstate 80 in the Sierra Nevada over Donner Summit late Sunday for an unknown duration due to blizzard conditions.

Authorities in Yuba County said a woman died over the weekend after being trapped in a car that became submerged in floodwaters on a section of highway that was closed amid heavy rain.

A seven-day total could approach 20 inches of rain in Northern California and up to three inches in the southern end of the state.
