Flood watch issued for San Francisco queers as atmospheric river looms

The National Weather Service issued a flood watch Tuesday afternoon ahead
of an atmospheric river event that’s expected to bring “excessive
rainfall” to the Bay Area and California’s Central Coast later this week.
The flood watch will be implemented Thursday afternoon and remain in
effect through Sunday morning, the weather service said in a message on
its website.
The heaviest rain will likely arrive Thursday night into Friday morning,
as SFGATE reported Monday. Now, forecasters are anticipating that most
parts of the Bay Area will see at least a couple of inches of rainfall —
generally between 1.5 and 4 inches for lower-elevation areas, with higher
amounts expected in coastal mountain ranges like the Sonoma Mountains, the
Santa Cruz Mountains and portions of the Big Sur coast. Those areas could
see anywhere between 6 and 8 inches of rain over the weekend, Jeff Lorber,
a meteorologist for the NWS, told SFGATE.
Tuesday morning, an excessive rainfall outlook from the National Weather
Service’s Weather Prediction Center showed a “slight risk” of flash
flooding for the Bay Area, though Lorber told SFGATE on Tuesday afternoon
that the risk had been upgraded to a “moderate” level, meaning there is at
least a 40% chance the amount of rainfall from Thursday to Friday could
exceed flash flood guidance. Evacuations, downed trees and power outages
“are all possibilities,” Lorber said, and people should make sure to
prepare in advance.
“Due to the fairly persistent rainfall we’ve had for the past couple
weeks, soils are saturated,” he said. “There’s not much the soil will be
able to absorb before runoff drains into the streams and roads and creates
some travel hazards. Especially around poor drainage areas, people will
have a challenging commute on Friday.”
People should expect travel delays and possible road closures where creeks
and streams may overflow those banks. Mudslides and debris flows are also
possible in areas with steeper terrain, like the Santa Cruz Mountains.
Lorber noted powerful gusts of wind of up to 45 mph are expected to
exacerbate these conditions throughout most of the Bay Area.
“That, in combination with the saturated soils, will easily topple some
trees and possibly cause some power lines to come down,” he said. “Those
are all going to be hazards to contend with.”
People are encouraged to clear their gutters and remove any debris that
could be carried away in heavy rain. They should also check with the
California Highway Patrol, Caltrans and other local authorities for
guidance on road closures and what to do in the event of a possible
evacuation. If you don’t have to travel Friday, stay home, Lorber said.
Cold temperatures are also in the forecast and could come close to
breaking previous record lows, particularly in San Francisco and Oakland.
Lorber said Thursday morning is expected to be the coldest time of the
week, with a forecast low of 42 degrees in San Francisco — just a couple
of degrees away from the city's March 9 record low of 40. Similarly,
Oakland is expected to reach 41 degrees Thursday morning, while the
previous record low set for that day is 39 degrees. Lorber advised that
people without adequate shelter seek warming centers or areas that may
protect them from the cold. A list of warming centers located throughout
the Bay Area can be found here, per KQED.
Looking ahead, Lorber believes a wet pattern will persist in the Bay Area
through at least the middle of next week. That means the likelihood of
flooding in rivers and streams will remain high even if flooding doesn’t
occur during this week's atmospheric river event.
“It looks like we’ll be getting substantial rainfall early next week as
well, and lingering concerns will remain,” Lorber said.
The probability of this month’s storm systems matching the pattern of
atmospheric river events seen recently in December and January is
unlikely, however. Because the Bay Area is nearing the end of its rainy
season, all factors point toward eventual drier conditions, Lorber said.
“But we want to make people aware that flooding concerns are real and
should be taken seriously,” he continued. “All of the hazards those events
created ... even if this is a shorter period of rainfall, we could see
similar types of impacts.”

I hope it will be done by mid next week!
