According to the FOX Forecast Center, gusts of 60-70 mph are anticipated in exposed locations such as ridges, headlands, and parts of the coastal plains. “The worst winds will occur Tuesday night and back off by Wednesday,” the center stated.

Blizzard in the mountains

In the Cascades, these strong winds will combine with heavy snowfall, creating hazardous blizzard conditions.

Travel conditions are predicted to become impossible from Tuesday evening through Wednesday morning.

As with most atmospheric rivers, this system is expected to bring significant snowfall to the Cascades and Sierra Nevada.

However, the influx of warmer Pacific air driven by strong winds will result in snow levels being higher than usual.

Blizzard Warnings have been issued for all of the Cascades from late Tuesday afternoon through Wednesday morning. This is where “high winds are most likely to overlap with snow and reduce visibility to a quarter-mile or less for at least three consecutive hours.”

Snowfall is expected to start at around 3,500 feet, with the heaviest accumulation occurring above 4,000 feet, leaving mountain ranges covered in several feet of snow.

Recreational boaters have also been warned to avoid venturing out to sea, while commercial vessels must prepare for extremely strong winds and hazardous seas. The best course of action is to remain in port until conditions improve.

A bomb cyclone, also known as explosive cyclogenesis, is a rapidly intensifying extratropical cyclone. It forms when the storm’s central pressure drops by at least 1 hPa per hour over 24 hours, creating a rapid and intense pressure drop.

This phenomenon is most common during the cold season, typically found about 750 km downstream from a mobile 500-hPa trough. It results in a powerful and dangerous system capable of bringing significant impacts to maritime regions.

With such severe warnings in place, mariners across the West Coast should take immediate action to protect life and property as this bomb cyclone intensifies.
