So the 12z GFS spins this in place for 48 hours before it heads west. Then it reaches the Caribbean on Tuesday (at 132 hours)

Here is the GFS output through 168 hours. Note that it starts at 90 hours.

The 12z GFS certainly is interesting and near the worst case, it stalls just offshore from CA near Belize and probably dumps huge rains like Mitch, then scoots off to the north/NNW and strengthens to a Gulf landfall...

This area is now designed as pouch PGI46L.

--------------------------------------------------------------------------------
Pouch Name: PGI46L Official Name: Initial Center Point: 10N 35W
Notes:

Staring very early with this one. There is a lot of uncertainty
at the start. Tracked at 700hPa ... perhaps I should have
tracked at a lower level.


--------------------------------------------------------------------------------
ECMWF: Phase Speed: -5.4 Determination: v700 only Level tracked: 700 hPa

Track: 120h, but very uncertain 0-36 hours. Initial OW max
moves eastward, then another moves southward from the north and
becomes the pouch that tracks westward.
GFS: Phase Speed: -1.5 Determination: v700 only Level tracked: 700 hPa


Track: 120h, but uncertain at 0-12 and 72-96 hours. The
uncertainty at the later period is most likely because the phase
speed is best at the beginning when the pouch is moving slowly
and not once it begins to move quickly westward at the end of
the forecast.
UKMET: Phase Speed: -3.1 Determination: v700 only Level tracked: 700 hPa


Track: 108h, but very uncertain 0-36 and 72-96 hours. The
uncertainty at the later period is most likely because the phase
speed is best at the beginning when the pouch is moving slowly
and not once it begins to move quickly westward at the end of
the forecast.
NOGAPS: Phase Speed: -5.2 Determination: v700 only Level tracked: 700 hPa

Track: 120h, but very uncertain 0-36 hours.

Got a break in between classes and all I can say is wow. Once again, I hope all Gommers are keeping up with this system (lurkers included). Chances of the Gulf dealing with this are increasing. On a positive note, still a long way out so we have time for things to change...hopefully.

The North central Gulf is hit this run because the trough is far enough north to induce a weakness for this to ride north. If the trough dug more, it would pick it up and head NE. If the trough is more of a shortwave feature and only erodes the western edge of the ridge, Texas is in danger. Progression and timing of the trough will be key, but there does seem to be continuity on the GFS of there being a trough.

1998 hurricane Georges seems to be a pretty good analog storm with regard to track only, compared to the current PGI45L models runs. It's mid September and a La Nina year?

well said ivan, i couldnt agree with you more here. im especially worried that texas residents think the hurricane season is over for them. its usually about over by now for us, but maybe not this year with la nina.

that hurricane georges track appears too far north in the caribbean. i think this will stay south of puerto rico, cuba, etc.
this one seems to be a caribbean low rider.

this is the time of year when we start to have to pay attention on the west coast of Florida. we rarely get storms, and to get a direct hit, they have to follow a very specific pattern that usually occurs either very early, or late in the season, when fronts can pull up and then turn a storm approaching from the south and direct it into west Florida.
1926 was the last time that Tampa Bay got a direct hit with a big one.

I wonder what that year's setup was like. Was it a la nina too?

As long as the lurkers aren't investors who lurk on this site to make an early "buy and sell" for their own profit - and make the rest of us suffer with higher gasoline prices, as the FTC has discovered over the past few hurricane seasons, when prices suddenly spiked based on Internet "chatter" (I'm referncing the term the Government uses)...

Per Ivan's post, what is seen in the models is a LONG way out and likely to change if not completely at least to a large degree - we all know what happened to Gaston and the endless "here we go" posts when a few thunderstorms began to appear - nothing, and is why we have to remember this site isn't just for a few weather fans, but is visited by many who could care less about the weather, but care about making money at the expense of others...

From this afternoon's NWS of San Juan discussion.

http://forecast.weather.gov/product.php ... glossary=1

THINGS COULD GET BUSY AGAIN IN THE LONG
RANGE. AN AREA OF LOW PRESSURE LOCATED NEAR 10N AND 40W LATE THIS
AFTERNOON...IS EXPECTED TO MOVE WEST DURING THE NEXT SEVERAL DAYS.
THIS AREA OF LOW PRESSURE...NEED TO BE WATCHED...IN CASE SOME
DEVELOPMENT OCCURS. RIGHT NOW...THE GFS COMPUTER MODEL IS THE MOST
AGGRESSIVE...DEVELOPING THIS SYSTEM IN A TC BY THE BEGINNING OF
NEXT WEEK...AND PASSING THE SYSTEM WELL SOUTH OF THE LOCAL AREA.
THE GFS FORECAST A STRONG MID LEVEL RIDGE NORTH OF THE LOCAL BY
MID WEEK...KEEPING THIS SYSTEM TO OUR SOUTH. MEANWHILE...THE ECMWF
MODEL SHOWS A MUCH WEAKER SYSTEM...APPROACHING THE CARIBBEAN BY
TUESDAY. RIGHT NOW..IS TOO EARLY TO KNOW EXACTLY IF THIS SYSTEM
WILL DEVELOP...AND WHICH TRACK WILL TAKE. STAY TUNED FOR FURTHER
INFORMATION DURING THE NEXT FEW DAYS.
