    A bomb hurricane hits Northern California and the Pacific Northwest heavy rain and strong winds The National Weather Service said Thursday that it had already been blamed for two deaths and warned that the situation would likely fuel flooding, rockslides, debris flows and more power outages.

    And worse weather is on the way.

    The first storm is forecast to continue through the weekend and produce an additional 6-12 inches of precipitation, the weather service said. An atmospheric river has led to a high risk warning for excessive rainfall along the Northern California coast.

    By 11 a.m. on Thursday, more than 300,000 homes and businesses in Washington state and 23,000 homes and businesses in California were without power. Winds gusted as high as 85 mph in Oregon and dumped more than 12 inches of rain on parts of Northern California, AccuWeather reported.

    Dave Houk, AccuWeather’s senior meteorologist, said areas already hit by several inches of rain will see more.

    “Heavy rain will fall for several hours and this heavy rain flow will target Northern California before it begins to ease on Friday,” Houk told USA TODAY.

    The developing storm system is forecast to shake the Oregon and Washington coastlines on Friday, adding to the region’s weather woes, Houk said. But it shouldn’t rage like the first one, which caused winds exceeding 70 miles per hour in some parts of the state, knocking down trees and power lines. The coast could see winds of 50 mph or more, Houk said, but Seattle should be relatively safe with winds of 25-30 mph.

    Still, some additional power outages and damage are possible, he said.

    “It’s not going to be as strong and it’s not going to get stronger as quickly,” Houk said. “Hopefully it doesn’t turn into what we’ve seen in the last few days.”

    Developments:

    ∎ More than 380 flights to and from San Francisco International Airport have already been canceled or delayed until 11 a.m. Thursday. The airport experienced more than 500 cancellations and delays on Tuesday.

    ∎ Up to 15 more inches of snow are possible in the Washington Cascades, which are already covered with more than 12 inches of snow. The storm could also reach inches into the mountain ranges of western Montana, Idaho and northwestern Wyoming by early Sunday.

    As Northern California grapples with the effects of the powerful storm, multiple roads were closed Thursday morning and vehicles on I-5 north of Redding were being scanned for snow chains. Redding, population 93,000, had received nearly 5 inches of rain since the storm began.

    An avalanche warning has been issued for Mount Shasta and other parts of Siskiyou County south of the Cascades, where heavy snow has been seen and rain is expected to follow.

    Farther south, a large truck driving in the rain early Thursday stabbed the Bay Bridge connecting San Francisco to Oakland, blocking four of five lanes and disrupting traffic for hours. One everything turned out fine around 9am

    Flash flood warnings for Bay Area counties north of San Francisco will remain in effect until early Saturday, the weather service said. The Santa Rosa area in Sonoma County received almost 7 inches of rain.

    Nancy Dienes was startled when a tall Douglas Fir tree crashed onto the roof of the Seattle home that Dienes and her husband, Tracy Matthews, have been renovating over the past few years. The couple did most of the work themselves.

    “When we bought it, it was a fixer-upper,” Dienes told KOMO-TV. “And it feels like a repair upper again. We already said we were going to rebuild.”

    A woman died Tuesday when a tree fell on a homeless camp in Lynnwood, north of Seattle, local officials said. A second woman died near Seattle when a tree fell on her home, Bellevue city officials said. Two people were injured when a tree fell on their trailer in Maple Valley, southeast of Seattle.

    Bellevue, Washington, Fire Department “Trees are falling all over town and falling on homes” published on social media when the storm gets stronger. “If possible, go to the bottom floor and stay away from windows. Do not go outside if you can avoid it. Emergency response teams are working hard to respond to weather events, but prioritize life safety first.”

    A. bomb cyclone A powerful cold-season coastal storm, so named because of its explosive power, is colloquially known as a winter hurricane. These types of storms go through a process of intensification known as storms. bomb formationThis means a rapid drop in atmospheric pressure, indicating the storm is strengthening, according to the National Oceanic and Atmospheric Administration.

    bombogenesis A storm is said to occur when the central barometric pressure drops by at least 24 millibars in 24 hours. Millibars are a way of measuring pressure. The lower the pressure, the stronger the storm.

    Some of the most intense winter storms to hit the nation’s coasts were bomb cyclones.

    The word “bombogenesis” is a combination of the words “cyclogenesis”, which describes the formation of a hurricane or storm, and “bomb”, which refers to its explosiveness.

    “This can occur when a cold air mass collides with a warm air mass, such as air over warm ocean waters,” NOAA said. “The formation of this rapidly strengthening weather system is a process called bombogenesis, which creates what is known as a bomb cyclone.”

    Atmospheric rivers, sometimes called “rivers in the sky,” are a major factor in extreme rain and snowfall in the West. They are very similar to surface rivers but can carry much more water than the Mississippi River.
