right now it would appear that this system has an inside track into Belize. High pressure is building in the northern GOM and over texas. But I really don't believe that the situation will stay like this for the next week (what are the chances?)....there is currently a small weakness east of Florida left by Chantal. I guess it will be filled in by a ridge over the next couple of days.
I still think if this system gains strength quickly it would end up a bit farther north. So far its staying on the weak side so it is heading west as expected. It should slow down once getting near the islands.
At this time I'm looking for it to move through the Caribbean and reach the West to NW Caribbean area where it could be a major hurricane. At that point I'm not sure where it will go....but anybody from South Texas all the way to the SE coast of the US should be closely monitoring the situation.

Latest HWRF (6Z) model has it in the NW Caribbean moving WNW on Sunday Morning perhaps going to miss or not miss the Yucatan.

Conditions moistening up to the west of 99L this morning!
Look at the atmospheric soundings this morning in Barbabos:
717.0 2968 9.6 7.5 87% 9.15 109 23 310.9 339.4 312.7

Re: Invest 99L East of Windwards #3
From the PR Forecast Discussion,
A DISTURBANCE LOCATED NEAR 11 NORTH 49 WEST AT 08Z IS FINDING ITSELF IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT...AND HAS SHOWN SOME ORGANIZATION. CURRENT MODELS SHOW IT MOVING BETWEEN WEST AND NORTHWEST DURING THE FIRST 24 TO 48 HOURS AND THEN TURNING MORE WESTERLY SO AS TO PASS SOUTH OF THE LOCAL AREA. CONVECTION CONTINUES TO BE ACTIVE...THOUGH IT IS INTERESTING THAT SATELLITE LIGHTNING REPORTS DO NOT SHOW ANY ACTIVITY IN THIS CONVECTION OR IN THE SHOWERS AROUND THE LOCAL AREA. THIS CONVECTION...HOWEVER...IS NOT SHOWING ANY TREND TOWARD FURTHER DEVELOPMENT AT THE MOMENT. MOTION SEEMS TO BE FAVORING THE MORE NORTHWESTERLY TRACK...BUT THIS MAY BE BECAUSE CONVECTION IS CURRENTLY BUILDING ON THE NORTH SIDE OF THE DISTURBANCE. MODELS ARE NOT AT THIS TIME LENDING MUCH PROMISE OF IT BECOMING A TROPICAL STORM...BUT IT BEARS WATCHING FOR THOSE IN THE MIDDLE OF THE EASTERN CARIBBEAN.

Re: Invest 99L East of Windwards #3
What is important is even if convection decreases for a time...it already has itself a good setup...the inflow is like a feeding tube...it will have no problem developing thunderstorms again

Hi Punkyg, for all of you folks that are asking for CyclonEye, he have his computer out of service at this time. The computer needs to be repaired and he is taking the proper action to do it. Thanks.

Re: Invest 99L East of Windwards #3
I don't want to burst anyone's bubble, but 99L is struggling this morning. Convection has taken a very disorganized look and it seems the system is being affected by southerly mid-level shear, which has disrupted its inflow. Of course, we have the dry air surrounding it at this time and yes... we have a very ill system. If this system is going to develop, it will not be today.
