The storm pictured below is developing rapidly Sunday night and will cause more potentially damaging winds over the Northwest. Ahead of this 3rd storm, winds gusted to 113 mph just after 10 pm Sunday night at Cape Blanco on the southern Oregon Coast. The storm will continue to strengthen... we call this "deepening" in meteorology because the pressure gets lower as the storm gets stronger... until Monday morning when it begins to weaken, or fill.

But it's still a very dangerous storm and will likely be stronger than the Sunday morning storm that caused the wind gusts listed below.

Offshore buoys measure swells for us. The giant waves will also increase as this 3rd storm works on the ocean's surface.

Both of these storms formed from moisture that originated in the tropics, from two former typhoons. Even though Monday's storm will be weakening as it makes landfall farther away from Oregon than Sunday's storm, it's stronger to begin with and the wind field ahead of it is very large. That means this is a long duration wind event (hence the giant swells) with gusts at least as strong as the Sunday morning winds. And this last in this series of storms brings more monsoon-like rains to the the Northwest. Already several inches have fallen in the valleys. Rain totals will push three inches in the valleys and eight inches in the mountains. There are a number of flood warnings up for area rivers.
Be careful out there!
