A Bomb Cyclone and Atmospheric River Are Developing in the Pacific. What Does That Mean for the West Coast?
What is a bomb cyclone?
A bomb cyclone is a rapidly intensifying low-pressure system that forms over the ocean. It is characterized by a central pressure that drops by at least 24 millibars in 24 hours. Bomb cyclones are often associated with strong winds, heavy precipitation, and coastal flooding.
What is an atmospheric river?
An atmospheric river is a narrow corridor of concentrated moisture in the atmosphere that transports water vapor from the tropics to higher latitudes. Atmospheric rivers are often associated with heavy precipitation and flooding.
How are a bomb cyclone and an atmospheric river related?
A bomb cyclone can create an atmospheric river by drawing moisture from the tropics. The atmospheric river then transports this moisture to the West Coast, where it can cause heavy precipitation and flooding.
What are the impacts of a bomb cyclone and atmospheric river on the West Coast?
A bomb cyclone and atmospheric river can have a significant impact on the West Coast, including:
- Heavy precipitation and flooding
- Strong winds
- Coastal erosion
- Power outages
- Transportation disruptions
What should you do to prepare for a bomb cyclone and atmospheric river?
There are a number of things you can do to prepare for a bomb cyclone and atmospheric river, including:
- Monitor the weather forecast and be aware of any potential storms.
- Stock up on food, water, and other essential supplies.
- Secure loose objects around your home and yard.
- Have an evacuation plan in place in case you need to leave your home.
Conclusion
A bomb cyclone and atmospheric river are powerful weather systems that can have a significant impact on the West Coast. By understanding these systems and taking steps to prepare for them, you can help to reduce your risk of being affected by their impacts.
