A massive bomb cyclone slammed into the Pacific Northwest on Tuesday night, unleashing torrential rains and tropical storm-like wind gusts up to 77 mph for certain areas. More than 600,000 customers across western Washington state are without power on Wednesday morning.  FOX Forecast Center said the powerful atmospheric river, coupled with a bomb cyclone, will unleash heavy rains and high winds across the area through Saturday.  “The two storms are powering the event, the first of which is a powerful bomb cyclone. The strength of the low has kicked up strong winds up and down the coast, which have caused power outages and some damage,” Fox Forecast Center explained.
