Survey Summary:
A team from the National Weather Service San Francisco Bay Area 
conducted a storm survey near Pescadero, San Mateo County. The 
team identified damage consistent with straightline winds. Damage 
was noted from the coast, just south of Año Nuevo State Park, 
eastward about 3/4 of a mile. This damage included, but not 
limited to, a hoop house visqueen cover being torn off, structural
damage to two hoop houses, a large water storage tank being 
transported over a 1/4 mile, and moderately large diameter coastal
cypress trees being snapped. There was one item seen transported 
counter to straightline wind flow and these were determined to 
have been caught up in very small scale temporary terrain driven 
rotation. There is no indication in the damage field of tornadic 
activity. While the radar signature did show rotation at elevation
while approaching the coast, it appears to collapse as it comes 
ashore, lending itself to thunderstorm outflow and a straightline 
wind event.
