SOUTH LAKE TAHOE, Calif. — A series of storms headed to the Sierra could cause flooding and landslides in the Caldor Fire burn scar, officials announced Wednesday.

The National Weather Service is forecasting a series of storms from Friday through early next week, with the highest level of precipitation expected Sunday night into Monday morning.

El Dorado County officials said in a press release on Wednesday that the conditions could trigger debris flow events throughout the Caldor Fire burn scar with particular impact in Strawberry, Phillips Tract and parts of Grizzly Flats.

“The upcoming weather event could result in flooding, causing currently unstable trees and other vegetation to fall onto roadways, create landslides, and impact our watersheds,” said Brendan Ferry, deputy director of the county’s Tahoe Planning and Stormwater Division. “Ash from the Caldor Fire and soil movement will undoubtedly occur and we are asking that all residents and travelers in these areas and along U.S. Highway 50 be on high alert for these hazards and take appropriate precautions to mitigate the storm’s impact.”

Officials said those in homes or vehicles near steep slopes, canyons, gorges and the mouths of mountain streams are at greatest risk of potential hazards.

An oncoming debris flow may include the sound of rushing water, changes in water from clear to muddy, or the sound of large rocks crashing into each other and typically occur within 15 minutes of a heavy rainfall.
