Powerful bomb cyclone forms off Western U.S. with record pressure drop

sea.mashable.com November 20, 2024, 11:01 AM UTC

A powerful bomb cyclone is forming off the Western U.S., characterized by a rapid drop in central pressure. Meteorologists report pressure drops of seven millibars per hour, potentially setting a record for extratropical storms. The cyclone is expected to bring high winds and heavy snowfall to the Northwest. It is also pulling in an atmospheric river, which will lead to extreme rainfall in Northern California, with some areas forecasted to receive over 12 inches. Atmospheric rivers are becoming more intense due to climate change, resulting in increased flooding risks. Local officials and the National Weather Service are advising residents to stay alert as the storm approaches.
