Mario Lopez among the victims of California mudslide chaos: Backyard of star's $2m hillside mansion collapses onto the street below after record rainstorms pound LA, killing four and wiping out properties 

• e-mail

TV host Mario Lopez was busy assessing damage to his multi-million dollar mansion after the backyard collapsed onto the street below.

The host of TV's Extra shared snaps and a video showing the gaping hole that has opened up after the hillside slipped following a torrential rainstorm in California.

'So, this is my yard today after City Public Works worked all night. Street below me is completely blocked,' he posted on his Instagram and adding the hashtag: 'CasaLopezIsWounded.' 

It was the third rainstorm to hit California in recent days and the unlikely weather system has left a trail of destruction and at least four deaths. Some homes were lashed with up to three feet of water.

But the record rainstorms hitting northern and central California also provided relief to the region after six years of drought.

The storms dramatically boosted the Sierra snowpack — a key source of water for California — to 158 percent of normal, the Los Angeles Times reported.

Northern California and Nevada rivers have also flooded, forcing thousands to flee their homes.

Judging from the images Lopez shared on social media, the ground broke away where a terraced garden area led from the home to street level. 

The slide took with it trees and shrubs as well as destroying steps and small lawn areas. 

According to listing details the Saved By The Bell star purchased the Mexican-style residence for $1.94million in 2010.

He lives there with wife Courtney Mazza and their two young children.

Lopez is just one of hundreds of residents to be affected by the bad weather.

This week 38 of California’s 58 counties were under a flood watch or warning.

In Guerneville in Sonoma County more than 12 inches of rain have fallen in the last week flooding the Russian River.

Jennifer Larocque, a spokeswoman for Sonoma County’s Transportation and Public Works department said hundreds of Sonoma County residents were displaced as the waters peaked at 37.7feet. 

In Sacramento, a tornado hit Wednesday morning, damaging trees and homes but not injuring anyone.

The damage to Lopez's home came two days after a 9,000-pound concrete foundation slab and a balcony collapsed from underneath a a $700,000 house in the Hollywood Hills.

The slippage forced the closure of Laurel Canyon Boulevard, a windy main road that links the San Fernando Valley with Hollywood, causing a traffic nightmare. 

Authorities have red-tagged the property, fearing the whole structure might collapse, and have asked the tenants not to return. They also told neighbors to stay away from their backyards.

The canyon thoroughfare remains shut to traffic and won't be reopened until Monday at the earliest. 

Heavy rains moved to the south of the state causing flood advisories to go into effect for the greater Los Angeles area on Thursday. 

More heavy rain is forecast for the middle to end of next week.
