Buoy is located at 31.978 N 69.649 W, so it's pretty close to Katia's center.

Lowest 1-minute Pressure
Time (EDT) Pressure
12:49 am 29.12 in
Highest 1-minute Wind Speed
Time (EDT) WSPD WDIR
11:57 pm 73.8 kts E ( 90 deg true )

Buoy data suggest that Katia is more around 75 knots than 70.

National Hurricane Center now has a message that a buoy shows Katia a "little" stronger.

OUTLOOK VALID 13/1800Z 62.2N 2.2E...POST-TROP/EXTRATROP

First time I remember seeing a forecast point beyond the prime meridian, although I'm sure there have been others.

Very funny wind probability map... good chance of TS winds over Canada and Alaska! Ha ha!

Must be that east coordinate that confused the system at 120 hours.

I think it's actually just how extremely far north it is. Spherical distance sucks :(

Looking at the vis loops Katia has maintained an eye or eye like feature for the past several hours and now looks to be strengthening, which should relatively short lived due to the decreasing SSTs.

Though the Atlantic has all ready produced several systems that have strengthened north of 30N so you never know...

If you look at the windspeed probabilities (very top of the map) it shows the cyclone circumnavigating the arctic sea.

I think that is an error, its predicted path takes it to the north-west uk at days 4 and 5. N60 is not so far north that it could bring tropical storm force winds to every longitude!
But it is a funny graphic and it would be interesting if the forecast points ever got that far north :)

From the latest discussion:
NO 96-HOUR POINT IS BEING GIVEN BECAUSE FORECAST POINTS IN THE
EASTERN HEMISPHERE BREAK A LOT OF SOFTWARE.

That is just... weird.

can someone please help me to understand why this is only 75kt. It has clearly been consistantly strengthening for about 18 hours now since it passed the buoy with 80kt winds yesterday. :roll:

Probably it is lower because some of the winds aren't transferring down to the surface.
