At least the middle part will be wild! A series of storms rolls in Tuesday with 3W weather: Warm, Wet and Windy! A High Wind Warning is up on the Coast for gusts to 65 mph and gusts should reach 40 mph in the Valleys. But the big weather story this week will be the rain. Our high resolution Futurecast computer model indicates as much as 10 inches of rain will fall in the Cascades and Coast Range and 2-3 inches inthe valleys. This is similar to the November 2006 rain event that caused the huge debris flows on the east side of Mt Hood that closed Highway 35. early season rains like this are especially good at creating landslides and debris because there's little new snow to insulate the ground from the rain.
Meanwhile at the Coast, it's not the ground but something high above that will augment the imapacts of this series of storms. Wednesday's Full Moon will create the highest tides of the month. That, along with all the water flowing of out coastal streams and rivers and huge swells coming in from the west will create a solid chance of tidal overflow flooding in the bays and rivers.
The good news is, beginning Friday we see a major shift in the weather pattern to warm and dry conditions that should last through the weekend and well into next week. Other than valley fog, we should see plenty of sunshine and mild conditions.
