The West Coast is in for a very stormy pattern over the next week that will result in a series of #storms that bring heavy precipitation, including snow in higher elevations. 🌧❄️ Check out our thread below for more details: ⬇️ accuweather.com/en/winter-weat…

2. The catalyst will be a #bombcyclone that forms hundreds of miles off the coast of western Canada and the northwestern U.S., which will result in a series of storms in the coming days: accuweather.com/en/winter-weat…

3. A ‘bomb cyclone’ or the process of bombogenesis, in weather parlance, occurs when a storm reaches certain meteorological benchmarks associated with rapid strengthening. Here’s a full explainer:

4. The storm’s central pressure is forecast to dip to approximately 28 inches of mercury (or 948 millibars), putting the bomb cyclone at or, possibly, even below the intensity level of Hurricane Larry, one of the stronger hurricanes of the Atlantic season: accuweather.com/en/winter-weat…

5. The Pacific Northwest is first in line for heavy rain and snow across higher elevation parts of Washington. The storms will bring some dangerous impacts, but the precipitation it will deliver to parts of Calif., Oregon and Washington is much needed 🌧 accuweather.com/en/winter-weat…

6. Seattle is one place that will be seeing some significant rain, something it needs after enduring its driest spring and summer in 77 years: accuweather.com/en/weather-for…

7. One of those dangerous impacts will be high winds. AccuWeather forecasters are calling for winds in the 40-60 mph range with gusts as high as 80 mph. Much of coastal Northern California is under wind advisories 💨 accuweather.com/en/winter-weat…

8. The bomb cyclone will also kick up some rough seas, particularly to the north. Forecasters expect wave heights near the Aleutian Islands to reach 48 feet high: accuweather.com/en/winter-weat…

9. And there will be snow. Up to 2 feet could fall over the highest elevations of the Sierra Nevada Mountains Sunday into Monday alone, and snow totals through next Wednesday could top 6 feet in some high elevation places ❄️ accuweather.com/en/winter-weat…

10. AccuWeather forecasters say there could be enough precipitation from this parade of storms to shut down what has been another destructive wildfire season across the West: accuweather.com/en/winter-weat…

11. The storms set in motion by the bomb cyclone will come one after the other, and by next week will begin bringing rainfall as far south as the Los Angeles area and possibly into San Diego: accuweather.com/en/winter-weat…
