Let's start by looking at the 9 PM infrared satellite image (below). Beautiful storm with the low center in the middle of the swirl nearly due west of the Oregon/CA border.
Another way to view the storm is using the water vapor channel that uses wavelengths in which water vapor emits radiation effectively. The dark area indicates dry air aloft descending towards the low center--the mark of a rapidly intensifying storm. The massive cloud shield is also classic for a powerful, rapidly intensifying cyclone.
The latest model forecasts are in and the forecasts are impressive. And I should note that virtually all modeling systems are providing a similar solution. Thus confidence is high.
At 2 AM Friday, a 976 hPa low center is off the southern Oregon, with an intense pressure gradient to its south and west. Classic for marine cyclones.
The wind speed forecasts will impress. Here are the gust predictions.
At 5 AM, the central and southern Oregon coasts are getting hammered with gusts to 60-70 mph.
By 2 PM, the strong winds have reached the southern WA coast.
The NOAA/NWS HRRR model for the same time (2 PM) shows some startling winds, with gusts to 50-60 mph in some places. These are serious winds, folks...perhaps the strongest of the winter at some locations.
There will be substantial power outages along the coast with downed trees and associated damage. Some power outages should be expected in the interior.
Help Us Determine the Local Impacts of Global Warming
Society needs to know the regional impacts of climate change and several of us at the UW are trying to provide this information with state-of-the-art high resolution climate modeling. With Federal funding unavailable, we are experimenting with a community funding to build this effort. If you want more information or are interested in helping, please go here.
