As requested by Srain many models have been looking at possible development in the western Caribbean late next week:

SHOWERS AND THUNDERSTORMS IN THE VICINITY OF THE WINDWARD ISLANDS
AND EXTENDING EASTWARD INTO THE ATLANTIC OCEAN FOR A FEW HUNDRED
MILES ARE ASSOCIATED WITH A WEAK LOW PRESSURE SYSTEM. ENVIRONMENTAL
CONDITIONS APPEAR CONDUCIVE FOR SOME SLOW DEVELOPMENT AS IT MOVES
LITTLE. THERE IS A LOW CHANCE...20 PERCENT...OF THIS SYSTEM
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

GFS indicates that development will be slow and this looks practical. This is looking like a large system and development is usually slow with larger systems. Also there is a giant weakness to the north with the trof and a general NW movement (once formed) should continue until the ridge builds back in and sends it west.

Oz Euro is a slow developer (and I mean slow as it takes another week before making it across the Caribbean) as it nears the YP and quickly strengthens in the GOM eventually hitting near Tampico. Slow enough in movement that there could always be a weakness to pull it up, otherwise this seems like a low runner.

The model observations have really gone downhill in a hurry at some of the other boards. To many people are doing nothing but wishcasting.

What I see in the models is general info that after mid month, the Caribbean and Gulf may become active. I wouldn't believe specifics from any model at this point, though.

SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A WEAK AREA OF LOW
PRESSURE LOCATED NEAR THE WINDWARD ISLANDS ARE SHOWING SOME SIGNS
OF ORGANIZATION. ENVIRONMENTAL CONDITIONS APPEAR FAVORABLE FOR
SOME GRADUAL DEVELOPMENT AS THE LOW MOVES SLOWLY WESTWARD. THERE IS
A MEDIUM CHANCE...40 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL
CYCLONE DURING THE NEXT 48 HOURS.
