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 another storm 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. The atmospheric river has caused a high risk warning to be issued along the coast of northern California due to heavy rainfall.

More than 300,000 homes and businesses were without power in Washington state early Thursday. Winds gusted as high as 85 mph in Oregon and dumped more than 12 inches of rain on parts of northern California, AccuWeather reported.

The developing storm system is forecast to shake the Oregon and Washington coastlines on Friday, adding to the region’s weather woes, the weather service said.

“High winds, mainly along coastal areas, are expected to cause strong waves and additional isolated power outages,” weather meteorologist Cody Snell said in a storm update released Thursday. he wrote.

Developments:

∎ Nearly 300 flights to and from San Francisco International Airport were canceled or delayed early Thursday, after seeing more than 500 cancellations and delays on Wednesday.

∎ 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 move within inches of the mountain ranges of western Montana, Idaho and northwestern Wyoming by early Sunday, Snell said.

Storm transforms her home into a ‘fixer shop’

A tall Douglas Fir tree crashed through the roof of a mid-century brick house in Seattle.

“When we bought it, it was a fixer-upper,” homeowner Nancy Dienes told KOMO News. He said he and his wife, Tracy Matthews, have done most of the renovations themselves over the past few years. “And it’s kind of like we’ve already said we’re going to rebuild a fixer-upper.

Two deaths reported in Washington

A woman died Tuesday when a tree fell on a homeless camp in Lynnwood, north of Seattle, local officials said.

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.”

What is a bomb cyclone?

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.”

What is an atmospheric river?

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.
