The West Coast of the United States has been subjected to some pretty harsh weather conditions over the past few days, all thanks to the Bomb Cyclone, a weather event that caused everything from mudslides to blackouts in some states. .
The cyclone, which occurs when winds suddenly become more intense due to a rapid drop in atmospheric pressure, hit the western part of the country, causing heavy rainfall and incredible wind speeds.
News week collapses where the United States was hit by the bomb cyclone.
Which states were affected by the bomb cyclone?
Initially, the bomb cyclone focused on the northwest of the country, affecting Washington, Oregon and, after moving further south, California.
However, upon his arrival on Sunday, October 24, other areas were also hit by high winds.
According to CNN, there have been 13 reports of tornadoes in Missouri, Illinois and Kansas.
On Monday, October 25, thousands of Californians were left without power due to the force of the event.
According to the National Weather Service (NWS), up to 10 inches of rain is expected to fall on the West Coast during that day, and the San Francisco Bay Area has been inundated.
Northeastern San Francisco, which was affected by wildfires before the cyclone hit, also suffered mudslides due to burn scars on the ground.
These scars from burns make the soil less stable, which means that heavy rains can dislodge gravel, stones and mud which then flow downstream.
Later that day, maps from the NWS suggested the storm was moving across the country, with even New York at risk of heavy rain.
A thunderstorm warning was put into effect Monday night for Maryland, Virginia and North Carolina. Flash flood warnings were then put in place from Massachusetts to New Jersey until late Tuesday October 26.
Currently, storm and tornado warnings are in place around Texas, Kansas, and Oklahoma.
What is a bomb cyclone?
Talk to News week, AccuWeather meteorologist Nicole LoBiondo said a bomb cyclone is “a rapidly strengthening storm with central pressure that drops 0.71 inches of mercury (24 millibars) or more in 24 hours. The process is called “bombogenesis”.
LoBiondo said that due to the long drought in the west, this cyclone brought much needed precipitation, although it still carried dangers.
Before the storm hit, she said, “The powerful storm will have dangerous and damaging impacts along the West Coast, but the precipitation it will bring to parts of California, Oregon and Washington is As the storm gathers a few hundred miles off the coasts of Washington and British Columbia, its intensification could easily exceed the criteria for bombogenesis. “
The time to be most vigilant, LoBiondo said, was Sunday through Tuesday, but she also warned that while there appeared to be a break in the storm pattern, next weekend another cyclone could have an impact on the region.
Accordingly, those living in areas prone to flooding should heed warnings from the NWS.
