Hurricane forming off Alaska coast?, page 2

I found this. So apparently they are known...just not considered tropical.
Mission News

But tropical cyclones aren't the only storms that generate hurricane-force winds. Among others that do is a type of storm that dominates the weather in parts of the United States and other non-tropical regions every fall, winter and into spring: extratropical cyclones.

Extratropical Cyclones: Meteorological 'Bombs'

Scientists have long known that extratropical cyclones (also known as mid-latitude or baroclinic storms) sometimes produce hurricane-force winds. But before QuikScat, hurricane-force extratropical cyclones were thought to be relatively rare. Thanks to QuikScat, we now know that such storms occur much more frequently than previously believed, and the satellite has given forecasters an effective tool for routinely and consistently detecting and forecasting them.

These storms, which occur near busy trans-oceanic shipping lanes, pose a significant threat to life and property for those on the high seas, generating high winds and waves up to 30 meters (100 feet) high. When they make landfall, in areas like Alaska, the Pacific Northwest, New England and the U.S. mid-Atlantic coast, they produce strong winds, high surf, coastal flooding, heavy rains, river flooding and even blizzard conditions.

Thanks liveandlearn! Now I can start pulling papers.

On a side note, isn't it an amazing time - when so many people from so many different places can share ideas and real time information and learn so much from each other?

I can't get the strikestarUS page to load for some reason, but I'll for sure keep an eye on the Environment Canada Lightning Detection site..

It's a cold-core low, as opposed to a warm-core, as in tropical cyclones. Expected conditions are 40-50 knot winds. Sea surface storm warnings in effect: Forecast

nice and symmetrical. Not particularly rare, but interesting to study.

1 knots = 1.15077945 miles per hour

Here's a converter for celcius and farenheit:

Here is the Environment Canada Satellite imagery that seems to have the most definition.

You are so right. I have learned a lot here. Had you not posted I would never have known to look it up.

I take it you guys don't watch Deadliest Catch?

In the episode they showed 2 weeks ago, which was shot much sooner I would imagine, they had 40-50 knot winds, and 40 foot seas.

The storms up there can get to be pretty violent.

Images, as well as the zone in which they form included in the link below.

Extratropical cyclone

Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are a group of cyclones defined as synoptic scale low pressure weather systems that occur in the middle latitudes of the Earth (outside the tropics) having neither tropical nor polar characteristics, and are connected with fronts and horizontal gradients in temperature and dew point otherwise known as "baroclinic zones".[1] Extratropical cyclones are the everyday phenomena which, along with anticyclones, drive the weather over much of the Earth, producing anything from cloudiness and mild showers to heavy gales and thunderstorms.

Haha no, I don't usually watch too much TV personally. Thanks for the link, so is it fair to say that this is ... An almost hurricane off of the coasts of Alaska/BC/the Yukon?

Thanks everyone for sharing your knowledge, thoughts, and links.

Captured this:



Here's an animation showing the formation in way more detail. Fascinating.

Probably an irrelevant
AND many people still are unsure / unconvinced

but this interesting crop formation appeared not too long ago....

from www.cropcircleconnector.com...

don't know why exactly, but I drew the impression of wind from this.
or maybe solar wind, the item in the centre perhaps being the sun.

We've had a recent re-awakening of the sun in terms of activity.

I think the circles are beautiful, but I think they're like Rorschach test's and due to their geometric and/or fractal patterns it's really hard to accurately interpret them.

I don't know too much about it honestly.

I once had to make a site that included weather reporting which worked off feeds from the weather channel. They would only give us the current images in the feed, nothing animated. So I took and saved the images over time and wrote a little program that turned them into animations.

The animations I put out to the public were over a time period of 4 hours worth, and it repeated over and over like you would see on TV. But privately, I kept an animation that ended up having over 6 months of weather in a single animated image. And I would watch the animation all the time and I would see odd things like what you see about them.

I also noticed the British get some crazy weather patterns. So if you want to see more "oddities" you should check that area out as well. They were odd to me anyway, maybe not so much to them.

It was really cool stuff, but I ended up losing the image in a computer crash, and once the site was done and sold, I didn't have access to have it make another. If anyone wants to shell out $1500 a month for the feeds, I'll make another.

The furthest I can go so far is 36 hours, but there's a striking similarity to some of the solar weather patterns I've been looking at too, maybe because it's fractal ...

Sucks that you lost that image, I'd have loved to have seen it. I'm gonna go on a search after I finish cooking dinner.

mmm chicken fried rice with snow peas, celery, corn, egg, sprouts, and my special blend of spices and kikkoman mMMm
