Two strong storms, a bomb cyclone and an atmospheric river, are forecast to collide and bring heavy rain

Two extreme weather events, a bomb cyclone and an atmospheric river, combined Saturday night and brought heavy rain, high winds and snow to the Pacific Northwest and Northern California. According to USA Today, more than 160,000 homes and businesses in California and 170,000 in Washington were left without power on Sunday due to the weather conditions.

Heavy rains caused flooding and landslides in parts of the Bay Area and Northern California on Sunday as a “bomb cyclone” and an “atmospheric river” pummeled the region.

A massive bomb cyclone and atmospheric river slammed into Northern California on Sunday, bringing flash floods to many areas. The Santa Rosa Fire Department released footage showing local flooding.

What people are saying?

Jordan Lindman That’s a Mid Latitude Extratropical Cyclone Not a Hurricane yes these types of Cyclones commonly Produce Hurricane Force Winds they are not a Tropical cyclone Hurricane by any How Means in this case this is Called a Bomb Cyclone since this storm dropped 55mb in 24 Hours.

parris k. butler Seems odd to me, warm moist air moving north and westward up the west coast (alaska) for several consecutive days in late october. i suspect that the term “atmospheric river” means, best not to explain this in terms of jet stream, low and high pressure systems and, cyclones.
