LLC IS FORMING!
TWD 2:05 EDT PM:
A strong tropical wave is in the NW Caribbean Sea from the
Yucatan Channel into the Gulf of Honduras moving W 10-15 kt.
Satellite images show a weak 1011 mb low forming along the wave
axis near 18n 88w. The low clouds over the Yucatan are
moving from N to S... suggesting the system has gotten better
organized overnight with a Ball of convection near the
disorganized circulation center. Proximity to land may inhibit
further development today but a building upper ridge over the SW
Gulf of Mexico could allow formation over the Bay of Campeche
tomorrow as the system moves into that area. Widely scattered
moderate convection is within 60 nm of the E coast of Belize and
Yucatan and also from 18n-21n between the Cayman Islands and
Yucatan.

This was his response:My only concern is that the upper high moves too far east and allows the system to move up it's west side. That would open the door for Texas. In fact the 12z NAM show almost that. It brings the tropical system up the coastline into central Texas by mid-week.
I know nothing about the likelihood of something like this happening .... so I'm wondering what the many more knowlegable hobbyists & pro mets on here think....

ok sorry this isnt really directly relating to 91L but I didnt want to get yelled at for starting a new post so I'm just gonna say something here...
so just to clarify things: there are currently 5 tropical disturbances in the Atlantic right now, correct? and one is Franklin, one is 91L which will likely develop in the Gulf, one is the E Atlantic tropical wave which is looking pretty good, one is a wave heading towards the Lesser Antilles: not looking to bad either, and the last is a weaker wave that is north of Panama- no development likely...

TROPICAL WEATHER DISCUSSION FOR NORTH AMERICA...CENTRAL
AMERICA...GULF OF MEXICO...CARIBBEAN SEA...NORTHEASTERN SECTIONS
OF SOUTH AMERICA...AND ATLANTIC OCEAN TO THE AFRICAN COAST FROM
THE EQUATOR TO 32N. THE FOLLOWING INFORMATION IS BASED ON
SATELLITE IMAGERY...WEATHER OBSERVATIONS...RADAR...AND
METEOROLOGICAL ANALYSIS.
BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1715 UTC.
...SPECIAL FEATURES...
TROPICAL STORM FRANKLIN IS CENTERED NEAR 27.4N 76.7W OR ABOUT 70
MILES... 110 KM... NORTHEAST OF MARSH HARBOR ON GREAT ABACO
ISLAND AT 22/1800 UTC MOVING N 7 KT. MAXIMUM SUSTAINED WIND
SPEED IS 45 KT WITH GUSTS TO 55 KT. ESTIMATED MINIMUM CENTRAL
PRESSURE IS 1007 MB. SEE LATEST NHC FORECAST/ ADVISORY UNDER
AWIPS/WMO HEADERS MIATCMAT1/WTNT21 KNHC AND THE PUBLIC ADVISORY
UNDER AWIPS/WMO HEADERS MIATCPAT1/WTNT31 KNHC FOR MORE DETAILS.
FRANKLIN IS A RELATIVELY SMALL SYSTEM WITH TIGHT BANDING
FEATURES AND AN ANTICYCLONE POSITIONED ALMOST OVERHEAD..
PROVIDING LIGHT SHEAR. THE CYCLONE HAS A GOOD CHANCE OF
STRENGTHENING OVER THE NEXT COUPLE OF DAYS BEFORE INTERACTING
WITH A MID-LATITUDE TROUGH. IT WILL BE INTERESTING TO SEE HOW
MUCH LATITUDE THE SYSTEM GAINS BECAUSE IT WILL BE CRUCIAL IN
DETERMINING HOW QUICKLY THE SYSTEM CAN RECURVE IF IT CATCHES THE
TROUGH. SCATTERED MODERATE CONVECTION FROM 25N-29N BETWEEN
74W-78W.
A STRONG TROPICAL WAVE IS IN THE NW CARIBBEAN SEA FROM THE
YUCATAN CHANNEL INTO THE GULF OF HONDURAS MOVING W 10-15 KT.
SATELLITE IMAGES SHOW A WEAK 1011 MB LOW FORMING ALONG THE WAVE
AXIS NEAR 18N 88W. THE LOW CLOUDS OVER THE YUCATAN ARE
MOVING FROM N TO S... SUGGESTING THE SYSTEM HAS GOTTEN BETTER
ORGANIZED OVERNIGHT WITH A BALL OF CONVECTION NEAR THE
DISORGANIZED CIRCULATION CENTER. PROXIMITY TO LAND MAY INHIBIT
FURTHER DEVELOPMENT TODAY BUT A BUILDING UPPER RIDGE OVER THE SW
GULF OF MEXICO COULD ALLOW FORMATION OVER THE BAY OF CAMPECHE
TOMORROW AS THE SYSTEM MOVES INTO THAT AREA. WIDELY SCATTERED
MODERATE CONVECTION IS WITHIN 60 NM OF THE E COAST OF BELIZE AND
YUCATAN AND ALSO FROM 18N-21N BETWEEN THE CAYMAN ISLANDS AND
YUCATAN.
...TROPICAL WAVES...
HIGH-AMPLITUDE E-CENTRAL ATLC TROPICAL WAVE IS ALONG ABOUT 37W S
OF 23N MOVING W 15-20 KT. DUST CONCENTRATIONS ARE QUITE THICK
WITHIN THE BROAD CIRCULATION OF THE WAVE THOUGH THE
STRATOCUMULUS CLOUDS ARE BREAKING UP A BIT AS THE WAVE ENTERS A
MORE UNSTABLE LOW-LEVEL ATMOSPHERE. STRONG SW WINDS ON THE S
SIDE OF THE WAVE ARE ENHANCING ITCZ CONVECTION WITH SCATTERED
MODERATE CONVECTION WITHIN 60 NM OF LINE 9N37W 11N28W.
TROPICAL WAVE IS IN THE LESSER ANTILLES ALONG ABOUT 61W S OF 18N
MOVING W 20-25 KT. THIS WAVE HAS ACCELERATED OVER THE PAST 24
HOURS AND ITS V-SHAPE IS DEGRADING A BIT ON SATELLITE PICTURES.
WIDELY SCATTERED TSTMS ARE FROM 12N-17.5N BETWEEN 58W-63W...
ENHANCED BY THE MID-OCEANIC TROUGH TO THE NW.
WEAK TROPICAL WAVE OVER THE S CARIBBEAN ALONG 72W S OF 14N
MOVING W 10 KT. THE BEST EVIDENCE OF THE WAVE COMES FROM TSTMS
OVER S AMERICA... OTHERWISE NO EFFECTS OVER THE AREA SAVE
PERHAPS AN INCREASE IN TRADES OVER THE CENTRAL CARIBBEAN.
NW CARIBBEAN TROPICAL WAVE IS NOW A SPECIAL FEATURE.

As it says in the 2:05 TWD, a circulation may be forming, and here are some reports that support the statement.
Belize City, Belize reporting SW Winds.
Puerto Cortez, Honduras reporting West winds.
Monkey River, Belize reporting SW winds.
Puerto Barrios, Guatemala reporting WSW winds.
I found this visiting accuweather.com international weather.

What does Hou NWS know? As for as I'm concerned they are the only ones discussing a strike on the northern Gulf by 91L. I have not heard of any other discussion including the NHC. Hou NWS is starting to lose credibilty with me fast.

For the record, Hou-Galv NWS only said they were monitoring the system and were keeping a close eye on it. To my knowledge they have not progged it to directly impact the northern Gulf coast.

No, the Houston/Galveston NWS office is not saying that this disturbance is heading our way at all. They are mentioning about the possibilities of it effecting our weather in a few days which could very well happen. Even if it comes ashore well to our south it will increase our rain chances. Read below.
IN THE TROPICS...THE LATEST FORECAST ON TROPICAL STORM FRANKLIN
KEEPS THE SYSTEM OFF THE U.S. EAST COAST. THE AREA OF DISTURBED
WEATHER IN THE NORTHWEST CARIBBEAN SEA IS EXPECTED TO MOVE TO THE
WEST NORTHWEST AND NORTHWEST INTO THE GULF OF MEXICO. THIS SYSTEM
WILL CONTINUE TO BE MONITORED FOR POSSIBLE DEVELOPMENT AND
POTENTIAL IMPACT ON OUR SUNDAY AND MONDAY WEATHER.

dog, y'all need one of those straight northbound systems that hits near Corpus and goes west of the Metroplex and rains itself out over you! However the angle of 91L doesn't look too promising for that.
