Summary of the situation
In the Tropical Weather Outlook NHC has tagged a tropical wave in the NW Caribbean Sea as Invest93L and believes that it has a 30-50% chance of developing into a tropical cyclone in the next 48 hours. As of now (11 PM PDT, June 26), the Hurricane Hunters are scheduled to investigate this area on June 28. The track models have Invest93L moving through the Yucatan Straits into the Gulf of Mexico. After that, most of the models take the cyclone north and east making landfall along a wide swath of Florida's Gulf Coast on Wednesday of next week. The intensity models predict that at landfall, the system will be a weak Category 1 hurricane or strong tropical storm.

Hi, this is Rob Carver, again filling in for Jeff Masters.
Invest93L is still present as of the 8am EDT Tropical Weather Outlook, but I'm extremely doubtful that it will reach even tropical depression status.
Invest93L's presentation on satellite imagery does not project the image of a strengthening storm. Convection, what there is of it, appears to be anchored over the Yucatan Straits and is not following the low-level circulation center. Also, microwave imagery indicates that the convection is weak, with relatively low rainfall rates.
It is worth noting that even if more convection forms after the circulation center moves into the Gulf of Mexico, there isn't much time for the storm to strengthen. By Tuesday evening, both the NAM and GFS 06Z model runs bring a weak front down into the Gulf, raising wind shear to the point that would dissipate Invest93L.
So, after considering the above, it's my opinion that Invest93L is not likely to intensify and will dissipate in a day or so.
