You can see on the Funktop that it does actually have a very well defined eye under the high clouds. If I couldn't see that I'd think it was a cat1 or 2.

I recall Hurricane Michelle in November 2001 had a similar satellite signature with 115 kt winds as it headed for Cuba.

This WV loop sure is interesting!

 

See the upper low E of Bermuda moving WSW quickly?  Look at the 250 mb 00z GFS loop

also attached.  That upper low ends up due N of the hurricane and that I think is what messes

things up for a curve back NW.  Didn't have this with Sandy.  Subtle things make *all* the

difference sometimes!

 

I also attached the 24 and 51 hr 00z GFS 250 mb for single panel reference.

Yep, a few pointed out yesterday that the ULL feature was the one providing the escape route. For some reason the GFS/others never saw it, or maybe they did but because they didn't anticipate the S drift/stall, and the ULL wasn't as strong as a factor earlier in the game. Timing is everything.

 

The combination of the two steering mechanisms is providing dual outflow channels for Joaquin, so at least that's pretty darn cool. This stuff never seems to happen in the Atlantic!

 

P.S. would not be surprised either if the latent heat feedback from Joaquin helped amplify the ULL to the east. Perhaps Euro also caught onto that more strongly.

Are you sure? It would seem logical to me that with the proximity to the US and our territories in the Carribean that the NHC would be responsible for US citizens who are boating or living in the area.

No, just, no. By that logic the NHC would.be issuing products for Japan because of US citizens who live and boat.near the island.

The GFS and Euro both saw the upper level disturbance dropping in from the north Atlantic and passing west around Bermuda.  The American models, et al, just never saw the southwest track like the Euro did.  On the American models Joaquin was able to lift north away from the Bahamas sooner(was forecasted to happen yesterday), which allowed the storm to get pulled in by the southeast US low just before the Bermuda weakness arrived to supply the escape route.  The Euro consistently dove Joaquin sw into the Bahamas, which delayed the turn north and allowed the weakness to move in first and open the door out to sea.  This appears to be a day 1-3 failure of the American models vs the Euro, not a medium to long range failure.

Looks like the media's completely abandoned ship with Joaquin.

Still needs to be monitored closely. If any still remember , the nam was the first model to pick Sandy accurately....all the while , they were all bashing it like crazy here "clueless nam" , etc....and it ended up being right.

 

No.  Euro from days out beyond NAM range.

There were several model runs ahead of that , where most models backed off (possibly ecm as well )..and only the nam still had a hit. I remember it vivdly.(since I was screaming nam , and was being flamed) If we can find a run/by/run analysis of back then , it will show it.

Maybe something here?   https://www.google.com/search?q=Weather+model+Nam+hurricane+sandy&espv=2&biw=1920&bih=1081&tbm=isch&tbo=u&source=univ&sa=X&ved=0CCkQsARqFQoTCLGksaWqpMgCFYZ0PgodD8MKmQ

Thanks. That makes sense. The models tend to do poorly with southward moving systems (Wilma, Katrina, Hanna, Mitch, Karl, Isidore, Gustav are some that come to mind). Something about the Euro caught onto the S drift whereas the American models did not.

Big story unfolding...

 

Contact was lost with a large cargo container ship with 33 on board in the Bahamas that was under duress yesterday. Unfortunately, it ended up in the very wrong place at the wrong time near Crooked Island as the core has been pounding the location for over 24 hours. NHC/recon has been assisting the U.S. Coast Guard. Recon attempted to fly as low as possible in the eye to find the missing ship. So far there has been no success to locate or reestablish contact.

 

I can only imagine the worst under those kind of prolonged violent winds and waves.

Yes, movement of ULL systems, partially over the eastern CONUS but really over the whole country for at least a month has seemed atypical. 

Where will this one affecting the cyclone move, let alone how will it develop?  It seems to have a large lower section as well that someone mentioned earlier in the thread, it is like a very deep trough wedged against the cluttered, retrograde flowing Atlantic.

You can see how if Joaquin was further north he would be forced westward into the EC by the same trough that instead is booting him out to sea.

HURRICANE JOAQUIN SPECIAL ADVISORY NUMBER 24
NWS NATIONAL HURRICANE CENTER MIAMI FL AL112015
1200 PM EDT SAT OCT 03 2015

...RECONNAISSANCE PLANE FINDS SEVERE HURRICANE JOAQUIN WITH 155 MPH
WINDS...


SUMMARY OF 1200 PM EDT...1600 UTC...INFORMATION
-----------------------------------------------
LOCATION...26.0N 71.6W
ABOUT 595 MI...960 KM SW OF BERMUDA
ABOUT 230 MI...365 KM NE OF SAN SALVADOR
MAXIMUM SUSTAINED WINDS...155 MPH...250 KM/H
PRESENT MOVEMENT...NE OR 50 DEGREES AT 16 MPH...26 KM/H
MINIMUM CENTRAL PRESSURE...933 MB...27.55 INCHES

 

...

 

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1200 PM EDT (1600 UTC), the eye of Hurricane Joaquin was located
near latitude 26.0 North, longitude 71.6 West. Joaquin is moving
toward the northeast near 16 mph (26 km/h), and this motion is
expected to continue through tonight with an increase in forward
speed. A turn toward the north-northeast is forecast on Sunday. On
the forecast track, the eye of Joaquin will continue to move
away from the Bahamas today, and pass west of Bermuda on Sunday.
However, a small deviation to the east of the forecast track would
bring the core of the hurricane and stronger winds closer to
Bermuda.

An Air Force Hurricane Hunter plane just indicated that the maximum
sustained winds have increased to near 155 mph (250 km/h) with
higher gusts. Joaquin is a strong category 4 hurricane on the
Saffir-Simpson Hurricane Wind Scale. A gradual weakening is
still anticipated during the next couple of days.

Hurricane force winds extend outward up to 70 miles (110 km) from
the center and tropical storm force winds extend outward up to 205
miles (335 km).

The minimum central pressure recently reported by a reconnaissance
plane was 933 mb (27.55 inches).

With Joaquin at 135 kt now, I believe this makes it the strongest Atlantic hurricane

to have its initial development outside the tropics (N of 25 degree latitude).  It first

became a TD at 27.5N.

 

Former record holder...Hurricane Diana in Sep 1984 first formed at 28.5N and peaked

at 115 kt.

Re: El Faro, pretty grim... 

 

 


On Monday morning, the Coast Guard here said it feared the worst: “We believe it sank in the last known position that we recorded on Thursday,” about 35 miles northeast of Crooked Islands, the Bahamas, Capt. Mark Fedor said. “We are still looking for survivors or any signs of life or any signs of that vessel.”

 

Of the 33 crew members, no survivors have been found. One person was found dead inside a survival suit, which is meant to keep people afloat and protect them from hypothermia. Coast Guard personnel also spotted a container, a cargo door and carpets of plastic foam used to pack goods in containers.
