Storms will be visible in Northwest, California
As cooler temperatures increase over the eastern US, the west is forecast to see heavy rain and mountain snow, with what is known as a “bomb cyclone” near the northwest.
Granthshala News’ Janice Dean said Thursday that some areas are expected to rise up to two feet, while california will reportedly experience debris flows, flash flood and mudslides – a major hazard, especially in areas prone to wildfires.

According to Seattle’s KCPQ, Bomb Cyclone is currently a few hundred miles west of the coast of Washington and the storm appears to be moving north.
The station said it appears the bomb cyclone “will not have much impact on the Pacific Northwest,” although wind advisories remain in place.
NS National Weather Service said Earlier on Thursday that cyclone responsible for developing an atmospheric riverbed aimed at the west coast and parts of British Columbia could bring rainfall totals between two and five inches in high altitudes.
So, what is a bomb cyclone and how does it form?
A bomb cyclone is also known as a mid-latitude cyclone National Oceanic and Atmospheric Administration (NOAA).

Mid-latitude cyclones drive most of the stormy weather in the continental US, agency note.
A process called bombogenesis can occur when a mid-latitude cyclone rapidly intensifies, collapses over a 24-hour period. at least 24 millibars of atmospheric pressure.
Generally, a range in millibar change is about 10 to 15 in the same time frame.
This can happen when a cold air mass collides with a warm air mass, such as wind over warm ocean water.
The formation of a rapidly strengthening weather system is bombogenesis, which generates bomb cyclones.
The effects of a rapidly evolving low-pressure system include high and intense winds and white-out conditions with blizzards and heavy snow, in addition to snowfall that can cause flooding.
It is not unusual to have at least one storm per year, and there are often no bomb-generations nor ‘Easters’ during the winter season.
