Cyclone’s Angry Eye over San Francisco

March 21, 2023

San Francisco Chronicle (paywall):

But despite the disconnect between the storm and the Pineapple Express, the storm did see a dramatic drop in pressure, falling below 990 millibars. This means it got close to reaching the benchmark that would’ve made it a bomb cyclone — a system whose pressure rapidly drops as it bursts into a powerful storm with an occasional eye at its center. But that’s only according to one definition of a bomb cyclone, where the pressure of a low-pressure system around 40 degrees latitude needs to drop by 17 millibars in under 24 hours. 

Scientifically, that’s an impressive feat for a storm off the coast of California, with the National Weather Service saying the range was one of the lowest recorded for the month of March.

    SF has
    – insane housing prices
    – high earthquake potential
    – recurrent exposure to wildfire smoke
    and now
    Wrath from the Pacific!

    And I thought the heat and drought of central Texas was bad….
