Tracking hurricane Joaquin OTS

FWIW... Steve DiMartino on Twitter: "As I stated, if Joaquin passed 75W, then this storm track must be adjusted back to the west."

Dude has always been a hypester. I remember late nights reading his posts regarding how the models were all missing this or that.

00z NAM is an EC hit.... in NE SC :lol:

 

In approx 57 hrs too

 

The only thing that makes that curious is that the 18z NAM was way out to see. The NAM is awful, but the fact it went back to a landfall scenario is curious.

 

Also, the fact the 18z ensembles came back towards an east coast hit as well.

I actually disagree... last year's March 21st storm he practically wrote it off because of surface temps... then we weltbulbed up here in PA and got 6 inches instead of his 1. He doesn't usually hype.

Curious or proof that it's worse than even we can imagine.

I think the 18z was trending toward an EC landfallbut like everybody says, the NAM is not to be trusted this far out.

I'm not totally sold this is finished. Big healthy storms aren't super simple to move quickly one way or another. See where it settles.

No other system has been such a "nail-biter" to date, in living memory. About the 4km being OTS, not a big deal. Been doing that when other models were west. 4km was 250 miles east of 0z on the last run.

HURRICANE JOAQUIN DISCUSSION NUMBER 17

NWS NATIONAL HURRICANE CENTER MIAMI FL AL112015

1100 PM EDT THU OCT 01 2015

The eye of Joaquin contracted in satellite imagery late this

afternoon, but has become obscured by cirrus clouds since that time.

Recent microwave imagery and aircraft observations have not shown

any indications of an eyewall replacement, but the intensity appears

to have leveled off for now. The aircraft has measured peak 700-mb

flight-level winds of 123 kt and reliable SFMR surface winds of 116

kt, which support an initial wind speed of 115 kt. Satellite images

show that the outflow is well established over the hurricane and

some additional strengthening is possible during the next 12 hours

or so. After that time, there could be some fluctuations in

intensity due to eyewall replacement cycles. Joaquin is forecast to

encounter increasing southwesterly shear in 2 to 3 days, which is

expected to cause some weakening during that time. However, Joaquin

is expected to remain a large and powerful hurricane for the next

several days. The NHC intensity forecast is near the upper-end of

the guidance in the short-term, and is close to the intensity

consensus throughout the remainder of the forecast period.

Recent reconnaissance fixes suggest that Joaquin has turned westward

and slowed down, with an initial motion of 260/3. The mid- to

upper-level ridge that has been steering Joaquin southwestward is

expected to quickly weaken overnight while a mid- to upper-level

trough over the southeastern United States deepens and cuts off.

This should cause Joaquin to turn northward on Friday, and move

north-northeastward at a faster forward speed Friday night and

Saturday. The model envelope has again shifted eastward, with the

GFDL and NAVGEM models now joining the other dynamical models which

keep Joaquin offshore of the United States east coast. This has

required another eastward shift to the NHC forecast, but it still

lies to the west of the multi-model consensus and the most recent

runs of the GFS and ECMWF models. The updated track is closest to

the GFS ensemble mean. Additional eastward adjustments could be

required to the official forecast overnight.

Surface and reconnaissance aircraft data indicate that Joaquin's

wind field has expanded during the past 24 hours. The initial and

forecast wind radii have been adjusted outward accordingly. The

increase in size has resulted in the issuance of a Tropical Storm

Warning for eastern Cuba where wind gusts above tropical-storm-

force have already been observed.

KEY MESSAGES:

1. Joaquin's slow motion means that extremely dangerous conditions

will continue over portions of the warning areas in the Bahamas well

into Friday.

2. The forecast models continue to indicate a track farther away

from the United States east coast and the threat of direct impacts

from Joaquin in the Carolinas and mid-Atlantic states appears to be

decreasing. However, the threat of impacts in Bermuda has increased

and a Tropical Storm or Hurricane Watch could be required for that

island on Friday.

3. Efforts to provide the forecast models with as much data as

possible continue, with twice daily NOAA G-IV jet missions in the

storm environment, and extra NWS balloon launches.

4. Even if Joaquin moves out to sea, strong onshore winds

associated with a frontal system will create minor to moderate

coastal flooding along the coasts of the mid-Atlantic and

northeastern states through the weekend. In addition, very heavy

rains, not associated with Joaquin, are expected to produce flooding

over portions of the Atlantic coastal states. Please see products

issued by local NWS Forecast Offices.
