ATL: JOSE - Post Tropical - Discussion

WPC issuing the advisory. Probably a full-scale test in case they need to take over for NHC.

Workload may be an issue too.

IF either: a) WPC is overloaded, or b) BOTH WPC and NHC are down, who is the secondary backup? I would think it would be the SPC or OPC.

I'd guess CPHC. You can throw a paper airplane from the OPC to WPC desks. Doesn't make sense for that to be a tertiary backup.

Yikes.

CPHC will do NHC backup for the EPAC if necessary (it's their primary backup), but luckily that shouldn't be an issue in the short term.

Speaking of the islands, how will they be able to communicate a potential second threat? Communications on some islands are really limited right now. This does look like a Luis-Marilyn situation.

Also, any plans for Recon? maybe on Friday?

A recent Windsat pass noted a 37-GHz cyan ring present in Hurricane Jose. Rapid Intensification is very possible at this time.

Core structure rapidly coming together. Would not be surprised to see a major by tomorrow sometime.

[1900hurricane]

Yeah, banding eye is showing up clearly on IR. Structure appears to be quickly progressing.

Were it to rapidly intensify at this stage, would that affect its track? If so, in what way?

Hurricane Jose Discussion Number 7
NWS National Hurricane Center Miami FL AL122017
1100 PM AST Wed Sep 06 2017

Jose's deep convection displays a tightly curved band that wraps at
least twelve-tenths around the center. Dvorak intensity estimates
from both TAFB and SAB have increased accordingly. Thus, maximum
sustained winds are analyzed for Jose at 75 kt, very close to that
from the CIMSS Advanced Dvorak Technique.

Jose is likely to continue developing during the next day or two
while the vertical shear is low, the SSTs are around 29C, and the
mid-level humidity is moist. However, beginning in two to three
days, the outflow from large, strong hurricane Irma to Jose's west
should start inducing more shear, inducing a steady weakening
by days four and five. The official intensity forecast is based upon
a blend of the LGEM, HWRF, and COAMPS models. Jose's anticipated
peak intensity of 105 kt is slightly higher than the previous
advisory, while days four and five show a more quickly weakening
system at that time.

The hurricane is moving toward the west-northwest around 15 kt, as
it is being advected along the south side of the deep-layer Bermuda
high. This motion should continue for the next couple of days.
During days three to five, Jose should bend toward the northwest as
it moves around the periphery of the Bermuda high. The official
track forecast is based upon the very tightly clustered guidance
(and their consensus technique - TVCN), which is somewhat west of
the previous advisory.

If future guidance further shifts westward, then tropical storm or
hurricane watches may be required for portions of the Leeward
Islands on Thursday.

Jose is a small hurricane with tropical-storm-force winds extending
out at most 70 nm from the center, based upon NDBC Buoy 41041 and
the 0006Z ASCAT-A scatterometer pass. The official size foreast -
based upon the RVCN consensus - suggests a gradual increase in size
for the next three days. Interestingly, buoy 41041 measured a
peak 1-minute wind (at 5 m anemometer height) of 61 kt around 22Z.

the hurricane hunters should consider dropping leaflets to get the warning out. May be the only way to convey a warning

[Evenstar]

Is it just me or does it feel nice and calm in this forum? It's like a quietly enthusiastic weather-nerd meeting in here.

[northjaxpro]

Jose is gradually becoming an impressive hurricane in his own right.The CDO is looking very impressive this morning and we should see the eye clearing out later today. Jose is in an intensification period right now.

Jose is also growing in size and I think Jose will become a major hurricane if this current organization trends continue. Wow, what a year this has turned out to be in the tropics. It is frightening to think that the models are latching onto Jose doing a loop( I.e. Jeanne '04) and building the HP ridge back in to steer Jose to the west towards the Leewards and eventually back to the Bahamas and Florida during the next 10 days. Unbelievable!!

[Gustywind]

Waouw, oh boy... warning and watches for the Leewards could be on tape today Don't like to read this type of weather forecast

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 500 AM AST (0900 UTC), the center of Hurricane Jose was located
near latitude 14.8 North, longitude 49.1 West. Jose is moving toward
the west-northwest near 18 mph (30 km/h), and this general motion
is expected to continue during the next couple of days.

Maximum sustained winds have increased to near 90 mph (150 km/h)
with higher gusts. Some strengthening is forecast during the next
48 hours.

Hurricane-force winds extend outward up to 15 miles (30 km) from the
center and tropical-storm-force winds extend outward up to 80 miles
(130 km).

The estimated minimum central pressure is 986 mb (29.12 inches).


HAZARDS AFFECTING LAND
----------------------
None.


NEXT ADVISORY
-------------
Next complete advisory at 1100 AM AST.

Eye is becoming more clear and very evident. Is it me or my untrained eyes? José is increasing a bit faster than what was expected if this trend continues.

[OuterBanker]

Absolutely amazing. Any other time there would be a hundred pages written on a storm that looks this good this far east. Irma (rightfully so) has all the attention. What an unbelievable year.

[CrazyC83]

Yeah, I fear the forgotten nature could be deadly...they really need to clear out Barbuda at least.

Hurricane Watch issued for the northern Leewards.

[Kazmit]

I believe abajan has already asked this, but how will intensity affect the track, if it does at all?

[Kazmit]

Slight east shift and slightly stronger days 4-5.
