Anatomy of a storm

January 12th, 2008

The January 4/5 storm that San Francisco and the west coast of North America experienced was a once in a decade event: impressive in scope and intensity. The coast in San Francisco saw 9 meter waves and high winds. About 2 million customers lost power (a ‘customer’ typically represents more than one person).

As the storm progressed, I grabbed some images from NWS Monterey (they’ve put up a page for the storm):

Atmospheric pressure plummeting at the San Francisco buoy.

Water vapor being entrained from just north of Hawaii.

11 am PDT. San Francisco is in middle of storm. Winds on Bay Area ridges reach a maximum of 160 km per hour, and on Sierra peaks they will be clocked at 240 km per hour. The Sierra will receive 2 to 3 meters of snow.
