8 p.m. update: The National Weather Service explained in a Facebook post why winds on the Oregon Coast may not have been as strong as anticipated.

NWS said the strength of a low pressure system is proportional to the strength of the winds, and the low pressure was 8-10 millibars less intense than forecasted, which they said makes a significant difference.

They also attributed the slightly weaker winds due to the fact that there ended up being two pressure centers instead of one, which they said causes the central pressure and winds to be less powerful.

Still, most of the Oregon coast felt winds from 60-70 mph. Meanwhile in the valley, winds peaked in the 50-55 mph range. The strongest gusts in at Portland International Airport were 53 mph.

A powerful storm developing from the remnants of a Pacific typhoon is gathering intensity off the Northwest coast.

The National Weather Service is warning about widespread damage when the storm reaches land Saturday afternoon and evening. Gusts along the central Oregon coast are already reaching 82 mph, and KGW Meteorologist Rod Hills says they could hit upward of 100 mph Saturday afternoon.

Inland, the winds are forecast to be weaker at 50 to 60 mph, but still strong enough to knock down trees and cut power to thousands. Wilde says the damage will be exacerbated because many trees still have their leaves, and thus catch more wind and are more likely to topple.

The storm is moving north and expected to rake Washington later Saturday. It follows a separate storm that brought a tornado to Manzanita, Oregon, Friday.
