Done.
I still see 10/20. I'm thinking this gets closed soon anyway and 99L declared...

TROPICAL WEATHER DISCUSSION
NWS NATIONAL HURRICANE CENTER MIAMI FL
205 PM EDT MON SEP 02 2013
A SOUTHWESTERN GULF OF MEXICO TROPICAL WAVE IS ALONG 91W/92W TO
THE SOUTH OF 23N...MOVING WESTWARD 10 KNOTS. A MIDDLE LEVEL TO
UPPER LEVEL CYCLONIC CIRCULATION CENTER IS NEAR 23N92W. A SECOND
MIDDLE LEVEL TO UPPER LEVEL CYCLONIC CIRCULATION CENTER IS NEAR
27N98W IN THE DEEP SOUTH OF TEXAS. THIS CYCLONIC CENTER HAS BEEN
MOVING SOUTHWESTWARD FROM THE UPPER TEXAS GULF COAST TO ITS
PRESENT POSITION SINCE 01/2315 UTC. A MIDDLE LEVEL TO UPPER
LEVEL TROUGH/SHEAR AXIS PASSES THROUGH 32N80W IN THE COASTAL
WATERS OF SOUTH CAROLINA AND GEORGIA...ACROSS NORTHERN FLORIDA
NEAR 29N82W...TO 26N88W...TO THE 23N92W CYCLONIC CENTER. IT IS
NOT EASY TO FIND CONVECTIVE PRECIPITATION THAT JUST IS RELATED
TO THE TROPICAL WAVE. CONVECTIVE PRECIPITATION...SCATTERED
MODERATE TO ISOLATED STRONG TO THE SOUTH OF 26N TO THE EAST OF
89W. SCATTERED MODERATE TO THE SOUTHWEST OF 25N96W 20N92W.
ISOLATED TO WIDELY SCATTERED MODERATE ELSEWHERE IN THE REST OF
THE GULF OF MEXICO. THIS SYSTEM HAS A LOW CHANCE OF BECOMING A
TROPICAL CYCLONE DURING THE NEXT 48 HOURS...AND A MEDIUM CHANCE
OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 5 DAYS.

Conditions of do look favorable for something to develop in the BOC or western Gulf with the upper low diving SW over NE Mexico.
I posted this about 4 hours ago and man did it blow up with the daytime heating, should be coming off the coast just south of Merida. lets see if it can maintain this convection, it probavly won't and the shear is a little stronger than I thought but it's still more interesting than 97L to me.

A TROPICAL WAVE OVER THE YUCATAN PENINSULA IS MOVING WESTWARD AT
ABOUT 10 MPH. THERE IS SOME POTENTIAL FOR DEVELOPMENT WHEN THE
WAVE MOVES INTO THE BAY OF CAMPECHE IN A DAY OR SO. THIS SYSTEM
HAS A LOW CHANCE...20 PERCENT...OF BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS...AND A MEDIUM CHANCE...30 PERCENT...OF
BECOMING A TROPICAL CYCLONE DURING THE NEXT 5 DAYS.

BOC is certainly the hotspot for formation this season, although short-lived systems.

Re: Tropical Wave in Yucatan / later to BOC: 20%-30%
If this system moves slow enough into the BOC, is there a possibility this thing could be pulled more north due to the approaching trough? Pro-Met or other. Possibly off to the NE towards Florida, say big bend area?
