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.

About 16 million people across central and Northern California, including
the San Francisco Bay Area and Sacramento, were under flood watches early
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.

“The combination of heavy rain and snowmelt may lead to flooding,” the
Weather Prediction Center said. “Creeks and streams in the western
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 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.

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.

The danger of rainfall on top of existing snow

Much of California stands to be impacted by this week’s expected
atmospheric river.

The Weather Prediction Center says parts of the state have a level 3 of 4
risk – the second-highest on the center’s scale – of excessive rain
Thursday into Friday.

The storm is expected to drop some significant rainfall on top of some
heavy snowpacks. The National Weather Service is expecting widespread
rainfall totals of 2 to 4 inches, with isolated amounts up to 8 inches.

“The uncertainty lies in how much rainfall will be absorbed by the
snowpack before there is significant release of that water into the
rivers,” the Weather Prediction Center said. “It’s likely some of the
(precipitation) will simply be absorbed into the many feet of snow at the
highest elevations, but lower elevations, generally below 5,000 ft, appear
most likely to not have the snowpack necessary to absorb the multiple
inches of rainfall expected.”

Additionally, the threat of heavy rain seeping into deep snowpack could
lead to the snow’s weight to increase, which can cause roofs to collapse,
the prediction center noted. “Affected communities are urged to remove the
existing snow from their roofs to mitigate this,” the weather agency
added.
