Some California Residents Are Urged To Prepare 2 Weeks Of Essentials Ahead Of Expected Flooding



Some California residents are urged to prepare 2 weeks of essentials ahead of expected flooding

Officials in California are imploring residents to prepare for a powerful storm set to lash the region with torrential rain later this week as the state continues to recover from colossal amounts of snow that trapped mountain communities.

Previous severe weather was responsible for the death of one person in the San Bernardino Mountains area. The San Bernardino County Sheriff’s Office said the person died in a traffic accident. Other deaths since February 25 don’t appear to be weather-related but investigations are ongoing, spokesperson Mara Rodriguez said.

About 17.5 million people across central and Northern California – including the San Francisco Bay area and Sacramento – and parts of Nevada were under flood watches Wednesday ahead of a storm set to drench the region Thursday with dangerous amounts of rain in most of the places that currently have existing layers of heavy snow from previous brutal storms.

“A storm arriving Thursday will bring a threat of flooding from a combination of heavy rain and snowmelt to lower elevations and foothills in California, especially below 5000 feet,” the Weather Prediction Center said. “And heavy, wet snow at higher elevations will lead to difficult travel and impacts from snow load.

“Creeks and streams in the foothills of the Sierra Nevada will be most vulnerable to flooding from rain and snowmelt.”

In response to the ominous forecast, officials in Marin and Monterey counties in California have begun preparations ahead of the looming storm, which is expected to strike the area as a strong atmospheric river event.

For the Big Sur community in Monterey County, the emergency services office went as far as advising residents and businesses to stock up on essentials that would supply them for at least two weeks. The county has also made sandbags available for residents who need them to protect their property. The Big Sur area, roughly 150 miles south of San Francisco, is one of central California’s renowned tourist attractions with picturesque rugged cliffs, mountains and hidden beaches along the Pacific Coast Highway.

Marin County’s fire department will have staff prepared for rescues in anticipation of possible flooding, county Fire Chief Jason Weber said.

“Our reservoirs are all full from storms earlier this year. With reservoirs full, we expect our creeks will rise more rapidly with most of the rain becoming runoff,” Weber told CNN.

Marin County, where a flood watch is in effect beginning Thursday, is home to one of California’s urban search and rescue task forces, and it will make its resources available for other counties as needed, Weber said.

This week’s severe weather threat comes as much of California has been hit with several back-to-back rounds of heavy snow that made roads impassable for days and knocked out power for thousands of residents as temperatures dropped.

Meterologist Katrina Hand of the Sacramento office of the National Weather service said when the storm first hits that area there likely will be some urban flooding, ponding and flooding from the smaller creeks and streams. Later, as the main rivers rise, more roads will flood.

Strong winds that could knock down power lines are also in the forecast, she said.

In hard-hit San Bernardino County, where mountain residents have been trapped in their homes, crews conducted dozens of rescues over the weekend, the county’s sheriff’s department said on Facebook. On Monday night, the county continued well-checks and community outreach, the sheriff’s department said. Despite the removal of large amounts of snow, some roads remained closed early Wednesday.

On Tuesday, volunteer helicopter pilots with the nonprofit Caldart delivered food, water and snow shovels to San Bernardino mountain residents via air due to the encumbered ground accessibility, CNN affiliate KCAL/KCBS reported.

In addition to the heavy snow that overwhelmed the state last week, more than a foot of additional snow has already fallen this week in some mountainous parts of Northern California. And Wednesday is expected to bring more to that region, where lower elevations could see between 1 and 6 inches of snow with isolated totals surpassing a foot of snow across highest elevations of the Sierra Nevada mountain range.

The impending atmospheric river event won’t be the first this year to lash California. Late last year and into the new year, multiple rounds of heavy rains from atmospheric rivers devastated much of the state – soaking entire neighborhoods and unleashing mudslides while killing at least 18 people.

Atmospheric rivers are long, narrow bands of moisture in the atmosphere that transport warm air and water vapor from the tropics. They can extend for thousands of miles and dump rain and snow when they make landfall.
