Remnants of 'bomb cyclone' or 'bombogenesis' hover over Bay Area as rain continues

SAN FRANCISCO (KGO) -- History was made on Tuesday as a "bomb cyclone" or "bombogenesis" hit the Bay Area for the first time in at least 15 years.

ABC7 News Meteorologist Mike Nicco explained what happened and has a look ahead to the rest of the week.

On Tuesday, Nicco said it started as a cluster of clouds but the low explosively developed, dropping more than 24MB in 24 hours.

It was such an impressive storm, it set an all-time record low pressure for the entire state. That happened in Crescent City.

Hurricane force winds occurred in Cape Blanco, Oregon - 106 mph!

The rain was impressive, too. Nearly three-quarters of an inch fell down in San Jose to more than 2 inches in Mill Valley.


Nicco says there's still a chance of scattered showers and thunderstorms Wednesday and, to a lesser extent, Thursday. That's why we're a 1-Light on the Storm Impact Scale.

There will some brief heavy rain, some possible hail and even snow down to around 2,500 feet.

Remember -- if thunder roars, go indoors for at least 30 minutes.

The bulk of the rain is mainly going to fall Wednesday and we have less of a chance of scattered showers on Thursday. It will be completely dry Friday before more rain rolls in this weekend.
