Winds Surging on the Coast
Very strong winds have hit the coast as the first trough moves its way northward immediately offshore (see weather map for 7 PM). Extremely strong pressure gradient over the offshore waters.
Winds at Hoquiam gusted to 61 knots (70 mph). And the second low is still out there...and starkly beautiful in the latest infrared satellite picture (see below). The new forecast models suggest that the second low will be too far north to give the Puget Sound lowlands a heavy dose of winds...so it appears the next few hours through 1 AM will be the main event.
Heavy rain continues over the Olympic Peninsula, the Willapa Hills, and parts of the Cascades. The latest values from the UW/SPU Rainwatch system are shown below...remember much of the mountains and SW of the Olympics is blocked (why we need a coastal radar!). Really, a coastal radar would have been a big help for this storm, with all the uncertainties in the complex pattern offshore that the models are getting only partially right!
