Extratropical Storm Igor Near Greenland

[cisa]

That is one nasty looking storm.

Could be reason for latest WSW movement:

Igor has to be the most impressive hurricane of the season so far. I notice with the map Andre posted, that there is a large area of high pressure over us.

Figured I'd share this here too. Forecast through 21Z tomorrow. The model crashed after that time, so that's as far as I have. It's for novelty purposes anyway.

Wow I have never seen a model like that. Very nice. Thanks.

I wonder if Hurricane Igor will be able to attain maximum intestiy of 175 m.p.h. or stronger? I for one woud not doubt it as good as that hurricane has intensified, thus far today.

Just so you know, Hurricane Igor currently has maximum sustained wind of 150 m.p.h, as of 11p.m. today according to KHOU's Hurricane Central, which is only ten miles per hour away from being a category five on the Saffir-Simpson Scale.

Igor is still moving west and even some hints at a wsw movement. It almost looks like that ridge over us is helping influence Igor to the west. Let's see if it turns tonight into tomm

Reposting track from last page. As you can see, there is a slight wsw movement as of late:

Very interesting to see on the 1km satelite view the stadium effect in the eye. Also its pretty cool to see the eye seeming to tilt as it wobbles along.

Great loop to see the intensification of Igor and I would expect tomm he will look even better than he did today. Still heading west as of 1:18AM:






After looking at the loop some more though you can see the trof to the North-West and it seems like it is starting to interact with Igor so the turn could be very soon.

[biggerbyte]

Still churning west....

Logic says at some point the turn should happen. But will it??

iWatch is in order..

I wonder if due to the restrengthening, that is why Igor is currently moving west. There have been instances where storms that get to this intensity create their own sort of "ridge". I noticed that when the turn started yesterday, it was in the process of weakening and now it is stronger than ever and is heading further west We will have to watch too see if this continues but as you can see below, the gap "ain't" big.
