Recommended Posts

Recon getting some nice SW winds now compared to earlier, pressure has dropped as well from earlier

You can see the surface circulation is just starting to become better defined closer to where the mid-level vortex has been looking well organized most of today. The wind shift has become more pronounced and the storm is probably no the verge of being named. Its clear, however, that the surface circulation and mid-level vortex are not yet perfectly aligned.

1006.8 millibars at 20.2N 86W. They were investigating the remnant low-level circulation as a new one formed near the mid-level center. Maybe enough for classification considering it's steadily becoming better defined on satellite. 

interesting as the wxbell 12z gfs maps didnt have it down to 1006mb until tomorrow.

Looking good...actually more than good. Now that it appears that a new LLC is consolidating farther N, under the better conditions, we may see some faster paced intensification for the next 24 hours...well into mid end TS. 

latest visible shots show storms firing right over the possible new coc.

That new vigorous convective burst is very close to the ML (and soon to be LL?) center of circulation may be the kick needed to entice genesis.

Recon now finding some 35 knot SFMR winds in the area of the convection, but the flow is southeasterly in the region, implying that if there is a center its still displaced west of the convective burst.

gfs is a tad weaker and a tad slower, still a decent ts though.  doesn't really ramp it up until it nears landfall and doesn't show much organization at all in the next 36 hrs or so.

 

EDIT: well i take that back, at landfall @ 96 hrs it is almost identical to 12z landfall strength, 75kt at 900mb.

If that's not a TD I'll eat my socks.  Outflow is great to the north, east, and SE.  Fairly moist environment and high TCHP.  Wish we had radar or a more recent TRMM pass.

We just had recon....low level was broad, ill defined and with multiple centers...not a TD. What dressing would you like with that?

TROPICAL WEATHER OUTLOOK

NWS NATIONAL HURRICANE CENTER MIAMI FL

800 PM EDT WED OCT 2 2013

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON TROPICAL

STORM JERRY...LOCATED OVER THE CENTRAL ATLANTIC.

AN AIR FORCE RESERVE UNIT HURRICANE HUNTER AIRCRAFT HAS EXTENSIVELY

INVESTIGATED THE BROAD AREA OF LOW PRESSURE OVER THE NORTHWESTERN

CARIBBEAN SEA...AND DETERMINED THAT THE SYSTEM DID NOT HAVE A

WELL-DEFINED CIRCULATION. HOWEVER...THE LOW IS PRODUCING WINDS TO

GALE FORCE AND HAS THE POTENTIAL TO BECOME A TROPICAL STORM AT ANY

TIME TONIGHT OR ON THURSDAY. THE LOW IS EXPECTED TO MOVE NORTH-

NORTHWESTWARD NEAR OR OVER THE NORTHEASTERN PORTION OF THE YUCATAN

PENINSULA THIS EVENING...AND INTO THE SOUTHERN GULF OF MEXICO BY

EARLY THURSDAY. THIS SYSTEM HAS A HIGH CHANCE...70 PERCENT...OF

BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS. AFTER

THAT...STRONG UPPER-LEVEL WINDS ARE LIKELY TO LIMIT DEVELOPMENT AS

THE SYSTEM APPROACHES THE NORTHERN GULF OF MEXICO BY THE WEEKEND.

THIS SYSTEM HAS A HIGH CHANCE...70 PERCENT...OF BECOMING A TROPICAL

CYCLONE DURING THE NEXT 5 DAYS. LOCALLY HEAVY RAINS COULD AFFECT

THE CAYMAN ISLANDS...PORTIONS OF CUBA...AND PORTIONS OF THE YUCATAN

PENINSULA DURING THE NEXT DAY OR TWO. INTERESTS IN THE NORTHEASTERN

YUCATAN PENINSULA...WESTERN CUBA...AND THE NORTHERN COAST OF THE

GULF OF MEXICO SHOULD MONITOR THE PROGRESS OF THIS SYSTEM.

I wonder if this may be one of those storms that skips over being a TD and goes right to TS.

goodluck out there you staying the whole time? I would love to be in your spot right now  :thumbsup:

It looks great, actually!  

 

I'm cool being in the WPAC-- not just because of FITOW but the cyclones coming after it in the coming week-- but this 97L is looking pretty awesome.

I'm still thinking future Karen will strengthen at least to 50kts in the next 24 hours....mid level low is just barely east of the broad low level center, which is actually good (the LLC being broad and ill defined), so that the current bout of strong convection will probably help the LLC consolidate below the MLC. Upper levels are pretty good with that anticyclone on top of the invest.
