Strong NW winds aloft battled very strong NW surface winds that curved into the bay causing squalls and calms from hell.
Check out today's Gulf Blog, which simulates winds at 5am and 4pm. Crazy strong winds can change during the day.
The story goes like this:
1. The North Pacific high pressure is abnormally large and located north of its normal location.
2. Its isobars are compressed to the California coast by Pacific storms to the west.
3. This results in strong northwesterly winds along the coast of Marin Pt. Reyes has shown 24g33.
4. In the morning, these northwest winds roar along the West Coast, then near Southern California waters, they curve inland…
5. The Great Basin Low pressure deepens as the cutoff low pressure far loft begins to form.
6. By this afternoon, this will result in a 98% pressure gradient between SFO and Winnemucca, Nevada, and therefore a very strong NNW to WNW into the Gulf.
7. At the same time, at approximately 1000 feet, very strong NNE to NNW winds hit the Coast Mountains, becoming turbulent and producing explosions, calms, and movements in the surface winds.
8. All this makes Pt. Winds from Isabel to Berkeley are unreliable.
9. As these winds hit the San Bruno Gap and mountains, they add up-and-down momentum to the surface winds at Coyote and Launch Site 3.
