A huge World War II structure perched atop a sandy California cliff reportedly tumbled down onto the ground after weeks of torrential rains led to flooding and saturation of the land.

The incident is the latest in a string of landslides reported across parts of Northern California battered by heavy showers. The structure, which was a former battery bunker, slid an estimated 200 feet down a cliffside onto San Francisco's Fort Funston beach -- home to huge ocean-side bluffs, SF Gate reported.

San Francisco Fire Department spokesperson Jonathan Baxter told the outlet the fall was due to a landslide that took place in one of those sandy bluffs.

The Golden Gate National Recreation Area shared a picture of the undermined structure on Twitter, urging beachgoers to exercise caution around "post-storm saturated hillsides and coastal bluffs."

"Beachcombers at Fort Funston will share the beach today with a WWII military structure undermined when saturated bluff sand slid onto the beach," the tweet said. "Coastal agencies encourage visitors to exercise caution around post-storm saturated hillsides and coastal bluffs as they enjoy sunny days after weeks indoors," it added.

Aerial video footage obtained by ABC7 showed the bunker sitting at the foot of a sand slide after the substantial fall.

Powerful rains and damaging wind gusts since New Year's Eve have caused over 200,000 evacuations and 19 deaths at the time of writing. Powerful storms sent out by the atmospheric rivers -- long regions in the atmosphere that transport water -- saturated steep hillsides, causing hundreds of landslides in January alone.

The record-setting storms have led to road closures, and sinkholes as they swept the state, as well as left hundreds of homes and businesses without power.

In a news conference Saturday in Merced County, California Gov. Gavin Newsom said the state has weathered as many as eight atmospheric rivers so far and is facing the prospect of a ninth to hit the state soon.

He said that the state has seen at least 22 to 25 trillion gallons of rain in just a matter of weeks. The deluge is forecast to end this week.
