A quick stop at Devil's Slide yielded this shot of a high-flying Peregine Falcon cruising slow enough to capture.

Full moon rising. It took about 20 minutes and 5 locations to get a shot through the rapidly forming coastal fog and low clouds. Enjoy. 3/2/2026

The California rainfall sesaon-to-date, showing mostly at or above normal precipitation through the end of February. (Note that the distribution of much-above-normal rainfall in the south half of Calif is 180Β° out of phase with a "typical La NiΓ±a" pattern as forecast.

Last week, most headlines led with β€œbelow normal snowpack”. But that’s only part of the Calif water picture, as the snowpack is basically just a β€œfrozen reservoir”. The 3 Sierra Precip Indices are a better metric, showing both frozen and liquid precip, and are all above normal!

High pressure and light offshore breezes pushed the mercury to 79Β° in Half Moon Bay this afternoon. This is the hottest February reading recorded in HMB; where offical NWS records go all the way back to 1939.
