Hurricane Irma

It's a big boy

They were thinking the pressure levels will not get that low, but they did. Well off Wilma though. Looks like they might have Jose following the same path as well which would be very unfortunate for the same islands just clearing up. As a point of note this will only be an important storm once it starts hitting the USA
With this

as someone who worries about whether my gin and tonic might be spilled during the flight back from Luxembourg I do take my hat off to them.

Maho Beach webcam has been destroyed. SXM TAFs were predicting 80 gusting 95KT before the weather monitoring station was presumably blown away. Looks completely wiped out. STT predicting 90G120KT later this afternoon.

Have they shut down and feathered that engine?
Probably just a fast camera exposure or the photo is reversed.They can and do shut down engines on the P3 Orion for increased loiter time, but it's normally only the outer engine on the port wing. They will very rarely shut down the starboard outer engine too.
The inboard engines have generators to power the avionics, so they're always kept running.
Threw me a bit in the name, NASA SPoRT.

I read it as sport, as in sports but it is short term prediction research and transition something or another.
Anyway, scary stuff in there.

Props are often seen to do odd things in filming and stills.
Off topic, but here's a good video that explains this effect...Fugazi said:

Off topic, but here's a good video that explains this effect...Yep, it is often seen in dash cam vide as well, the wipers, when they are on.Method of capture is important to understand. I suspected it was more of a still capture form a high end camera or video though.
Edit. Did not see it as feathered as such.

Now looking at Jose hot on Irma's tail.
https://www.windy.com/?2017-09-08-09,17.811,-66.44...Move the prediction timeline along the bottom of the screen, Jose is dragged north by the wake of Irma before coming back as Irma blows itself out over the land, another one building behind Jose, looking menacing by next Saturday.

Hadn't seen that before - now bookmarked ! ThanksBeati Dogu said:
It's good isn't it?
You can clearly see Irma, Jose and Katia, which is the one rolling around the Gulf of Mexico.
Certainly is, thanks. Wunderground do a nice montage as well that can watched with that to get an idea if you look at bothYou can clearly see Irma, Jose and Katia, which is the one rolling around the Gulf of Mexico.

you might need to zoom out, shows the tracks and strengths at certain times.

Stronger winds actually happen on the actual land in Antarctica, though that is not downplaying the southern ocean depressions.Cold dense air flows from the interior at higher elevation down to the coast. This causes katabatic winds.
A very good summary http://www.anta.canterbury.ac.nz/documents/GCAS_7/...
They average less than a Cat 5 cyclone but can last for days, -
From February 1912 to December 1913, scientists measured the wind speed at Cape Denison, a rocky point at the head of Commonwealth Bay in east Antarctica. To this day it is recognised as the windiest sea level station on Earth.
The windiest hour was recorded on 6 July 1913 at 95mph (153km/h). On the widely-used Beaufort scale of wind speeds, Cape Denison's annual average wind speed is gale force.
According to Sir Douglas Mawson, who led the expedition to Cape Denison, "the climate proved little more than one continuous blizzard the year round; a hurricane of wind roaring for weeks together, pausing for breath only at odd hours."
The combination of ultra-strong winds and sub-zero temperatures means it is actually rather hard to measure the strength of katabatic winds.
For one thing, when the winds are really up they can destroy the measuring instruments and the masts they are attached to. But even when the gusts are gentler, propeller- or cup-style anemometers can ice up in the cold. It is possible to use ultrasonic anemometers, which don't have any moving parts and can be heated to avoid icing problems," says King. "But these don't work well at high wind speeds when there is a lot of blowing snow in the air." All in all, Antarctica is a challenging place to measure wind."
And at least you can do some sunbathing on Necker Island when it has passed
Two twitter posts to watch

They know each other and so cross tweet. They will give you all you need to know in the coming week if you are interested in this sort of stuff. One is removed from there, Colorado and one is working is the storm at the Hurricane centre, so more personal even though he is a scientist( he has borded up his house already). Will be good to see how they report it between them if it does hit Florida head on.
Could be a good social experiment for psychologists. Book mark them both,
Of course if it does not whack Florida / Miami then my experiment goes awol immediately.
