- In California, power lines tumbled and more than 100,000 homes and businesses were in the dark early Monday.
- Flooding and mudflows caused long stretches of I-80 to be closed.
- The 24-hour rainfall record for Downtown Sacramento was also broken with more than 5 inches.
- The East Coast was waiting for storms to hit.
A broad swath of California was under siege Monday from high winds and historic rains fueled by “bomb cyclone” conditions that triggered mudslides, flooding and power outages.
The so-called atmospheric river was fueling record-breaking rains while wind gusts approached 90 mph – hurricane strength – in some areas, the National Weather Service said.
Mt. Marin County’s Tamalpais, located 20 miles northwest of San Francisco, saw more than 16 inches of rainfall over 48 hours. St. Helena, a city of 6,100 in wine country, saw more than 10 inches.
The Bay Area Weather Service tweeted that “It looks like 4.02 ins of rain” for downtown SF. “By far, the wettest October day ever… Fourth Wettest day EVER to SF Records back to Gold Rush.”
Bomb Cyclone, Atmospheric River Blaster West Coast 2 dead in Seattle area, hundreds of thousands without power
The East Coast, which is almost 3,000 miles from New York City was anticipating the arrival of the storms. AccuWeather meteorologist Joseph Bauer warned that heavy rains and winds could choke New York City’s morning commute, with 3 to 5 inches of rain possible Tuesday and Wednesday. More severe weather could be expected from the East as a result of the storms currently ravaging California.
AccuWeather’s senior meteorologist Brett Anderson said that “the same huge storm that has been bringing rain, snow, and strong winds to the Western US is now expected to move slowly eastward across our country.”
Meteorologists say the bomb cyclone – a rapid drop in atmospheric pressure – helped drive the long, wide plume of precipitation onto the West Coast. In California, power lines tumbled and more than 100,000 homes and businesses were in the dark Monday. Washington also had 50,000 people affected by the storm. Two people died when a tree fell upon a vehicle in Seattle.
Flooding and mudflows closed long stretches of I-80, and all other highways. The National Weather Service reported that several places set 24-hour rainfall records. Blue Canyon North of Sacramento had more than 10 Inches.
Also, Downtown Sacramento set a 24-hour rain record of over 5 inches. A shelter was built at City Hall.
Mayor Darrell Steinberg declared that the city hall is also for those in the worst of circumstances. “I’m really proud of the fact that we are opening up the people’s building to bring people indoors.”
More than 100 miles to the south and closer to the Bay area, I-880 between Newark and Fremont was was closed overnight after half a dozen cars were overwhelmed by water. Martinez captured videos of people walking in floodwaters around their neighborhoods.
Parts of San Francisco were swamped, and Mayor London Breed urged residents to call 311 to get help for people in need of shelter and 911 for medical emergencies.
Breed tweets, “Help your local community by checking-in virtually with family and friends who may require assistance during extreme weather.”
San Rafael police stated that downtown San Rafael was shut down to any traffic other than essential after several roads were flooded.
Heavy snow was pounding high elevations of the Sierra Nevada. Because of the proximity of wildfire burn scars to several locations, such as Santa Cruz Mountains or parts of west Santa Barbara County, many areas were given evacuation orders.
Late in the day, heavy rains were sweeping across Southern California.
Nor’easter may be West Coast’s bomb cyclone.
AccuWeather reported that storms formed over the Pacific Ocean and are moving west-to east across the United States. There have already been severe thunderstorms, heavy rain, and thunderstorms along the nation’s midsection. In Missouri, there has also been reports of possible tornadoes.
For the Ohio River valleys and Tennessee River Valleys, severe thunderstorms were expected. However, rain and showers will continue to spread further north. AccuWeather stated that the storm would intensify as it travels across southern New England by Tuesday. It will continue to rain heavily and cause windy conditions for residents.
“An early season tempest could bring a wind-driven, chilly rain to portions of the Northeast from Monday through Wednesday,” Adkins said.
Flooding downpours will reach from southern Maine to eastern New York in cities such as Boston and Worcester, Massachusetts, which are expected to pick up 4 inches of rain, with localized totals reaching 8 inches in some areas as the storm intensifies off the coast, AccuWeather forecast.
From the Jersey Shore, to the southern coast of Nova Scotia, winds are likely to gust between 40-60 mph Tuesday through Wednesday.
Cities such as Provincetown, Plymouth and Boston, Massachusetts, could experience wind gusts as high as 80 mph Tuesday night, AccuWeather said.
By Thursday, the nor’easter will move out ot sea — but another storm built on remnants from the “bomb cyclone” that walloped California on Sunday is expected to approach from the west, dousing East Coast trick-or-treaters next weekend.
