Strong Pacific storm to bring mainly-minor impacts locally – KIRO 7 News Seattle

Certainly it is meteorologically interesting, as an unusually severe depression is developing hundreds of miles off the coasts of Washington and Oregon. It will go through a phenomenon called “bombogenesis,” a term that means a rapid deepening / strengthening of an area of ​​low pressure. (This is where the term “bomb cyclone” comes from.) The winds around this cyclone will be quite strong tonight through Thursday, until it hits land tomorrow night at Haida Gwaii – way up on the BC coast.

If that storm were much closer, we would certainly have a big impact in West Washington. But we won’t. The storm will be too far away for anything but minor impact – pretty typical fall weather. There are NO wind clocks, warnings or advice for any part of West Washington and I really don’t expect any. There is a storm warning in the coastal waters on Thursday.

Here are the special features:

By tonight, expect some shower periods but persistent stormy conditions with gusts of wind in the 20-30 mph range through Thursday morning. As the depression hits its peak on Thursday, it will quickly move north towards the central / north coast of BC. These places from Tofino to the north will experience noxious winds.

In West Washington, we can expect gusts of wind of up to 40 miles per hour at times along the central and northern coast of Washington as well as at the western entrance to the strait on Thursday. The time of the strongest winds in our area is noon on both sides. Away from the coast and the strait (including Puget Sound), we will still have gusts of wind in the 25-35 mph range on Thursday, similar to today. Hold on to your hats! Leaves are flying everywhere! But not uncommon for October.

There is also a slight risk of thunderstorms until Thursday – until tonight mainly near the coast and on Thursday mainly on the coast and the Olympic Peninsula and south of Seattle.

It will be unusually mild and humid on Thursday with highs in Seattle in the mid-1960s!

On Friday it gets cooler with occasional showers and sunburns. It will stay a little airy. Highs will be in the 50s. Snow depth will drop to about 4,000 feet (Stevens Pass.)

This weekend you can expect cool temperatures with lowland highs in the 50s and the occasional rain and mountain snow. Whether we will have any problems driving the pass is unclear, but temperatures can be cold enough at any time from Saturday to Monday to even snow as far as Snoqualmie Pass.

It’s also likely to get breezy again from Sunday afternoon to Monday morning as another low pressure area passes our state. This next system is to be watched as getting closer to the storm center or a deeper depression than currently forecast could bring stronger winds to the area to end the weekend or start next week, but right now there is nothing to worry about . We’re just going to watch how the forecast develops in the coming days.

Expect inconsistent weather with rain and mountain snow until next week. With all the rainfall in the coming days, we could see some minor floods along some rivers by next week.
