Large Bomb Cyclone Impacts Western US Coastline, Satellite Imagery Shows

A bomb cyclone impacted much of the west coast of the United States on March 28, according to satellite imagery from the Cooperative Institute for Research in the Atmosphere (CIRA).

Ahead of the storm, the National Weather Service (NWS) warned those in the California Bay Area and Central Coast to “expect gusty winds and moderate to heavy rain,” as well as urban flooding, downed trees, and the possibility of isolated power outages.

“If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency,” a subsequent NWS update said.

By Tuesday, upper Northern California had begun feeling the first effects of the storm, with more than 14,000 people in Del Norte, Siskiyou and Shasta counties losing power for several hours, according to the Los Angeles Times.
