Strong Wind Moving Onto Coastline

March 9, 2016

3:30pm…

Everything appears to be working out well so far…lots of gusts 55-65 mph at the usual coastal spots and of course the real exposed (higher) locations are stronger. I see an 81 mph gust at Meares Hill (1,400′) and 90 mph gust on top of Mt. Hebo (3,000′).

As mentioned yesterday, the storm is so far offshore that we won’t get damaging wind in the valleys. Maybe a few thousand power outages and a tree or two down somewhere, but that should be it. But the big story is at the coast.

COAST: High Wind Warning
Wind has arrived at the coast with lots of 55-65 mph gusts so far. Wind will ramp up another 10-20 mph for the next 4-8 hours. Gusts 65-75 mph are likely with a few exposed spots likely up in the 80-90 mph range.

VALLEY: Wind Advisory
Light wind so far (as expected). Breezy southerly wind picks up, mainly after 7pm. Gustiest wind in the middle of the night, like 10pm-1am. Gusts 35-45 mph. It SHOULD be a bit lighter than what we saw last week.

All wind backs off later tonight.

HURRICANE FORCE WIND WARNING: You have have heard about this. THIS WARNING IS NOT FOR ANYONE ON LAND. It’s a marine warning for the coastal waters, strongest wind out there since the storm is so far offshore.

Latest HRRR model run seems reasonable, showing strongest gusts at the coastline in the 6-9pm period:

hrrr_gust_portland_7

and inland around 10pm-midnight (note yellow spots showing gusts 35-40 mph):

hrrr_gust_portland_10

Hold on if you live at the Coast!  And enjoy a showery/breezy night here in the valleys.
