South Lake Tahoe battling severe flooding, structure collapses amid impacts of atmospheric river
The city of South Lake Tahoe is battling severe flooding and structure collapses as the atmospheric river continues pummeling Tahoe Basin.
"What the F is going on, did you just see that? It went flump," said tourist Vicki Herbert. "I'm a little worried the roof is going to go, showmp!"
Near historic snowpack, compounded with heavy rainfall has left businesses taped up, closed down and unsafe to occupy across South Lake Tahoe.
Dramatic images show snowpack towering over the roofs of homes and businesses - as the city has tracked 500 inches of snowfall so far this season.
"That's the concern with the incoming rain coming atop that snow, we're doubling and tripling a lot of that weight," said Jim Drennan, South Lake Tahoe's fire chief.
Drennan warns that the wintry mix is a double threat.
"Is this double threat, the worst you've seen it?" ABC7's Stephanie Sierra asked.
"Yeah. We've worked through a lot of heavy winters. 2011, 2016/2017 heavy winters, but I haven't seen it this bad," Drennan said.
The heavy snow load crumbled an awning at Swiss Mart gas station along Emerald Bay Road. It's one of at least seven structures that have collapsed across the city during the storm.
"When it failed, it crashed into the gas pumps, and we had a gasoline-fed fire," said Drennan. "No injuries of any kind but that property has been red-tagged."
From tumbled structures to parking lot swamps - businesses and emergency responders have remained on high alert.
"We have lost 3/4 of our parking lot due to snow plows, keep having to stack them higher and higher," said a manager at Grocery Outlet, where a parking lot flooded.
It is a reality for the region as these snow mounts start melting, flooding out residential streets and the city's airport runway.
"I left 75 degrees in Austin, Texas," said Herbert. "I'm kind of in culture shock."
The city is cautioning against unnecessary travel for the next several weeks as the Basin struggles through the snowmelt.
"We can see landslides, mudslides," said Sheree Juarez, South Lake Tahoe's public information officer. "It's being watched carefully, so you can expect delays for a long period of time."
The city says avalanche control is in effect which could impact travel on Highway 50 and Highway 80.
