Florida At Risk for Vigorous Tropical System

Florida is at Risk for a tropical system of some sort in the coming days. Below is the track and intensity plot of Invest 95L, currently on land near the Yucatan Peninsula region.
Intensity Plot

Track Plot
Several models are indeed indicating that this invest will move northeast, through the Gulf of Mexico, and make landfall on Florida's coast. The invest will then barrel through Florida and out to sea. However, I do believe that these models are underestimating the intensity. Below is current Sea Surface Temperatures in the Gulf.
One thing you may not realize is how warm these temperatures actually are. When calculating, the values are in Celsius. However, when you put in 28.5 degrees celsius (the most widespread temperature across the Gulf), you get 83 degrees Fahrenheit. This is a very warm Gulf Temperature and is actually not too far off from summer temperatures. Since no system has crossed the Gulf yet as a defined Tropical Storm or stronger, these warmer waters have not been disturbed, leaving them to wait for a new system, which may be this one. So yes- I do believe this system will develop into something of a hurricane under these conditions. I am not completely sure because of some possible over-shearing, but that remains to be seen.
This system currently has a 50% chance of development over the next 48 hours. Satellite imagery would indicate the majority of the system is over water, so let's take a closer look at some more defined imagery.
This image also shows the main convection over water and likely gathering strength at this time. That we are not sure of but seems to be a rule of thumb. Anyways, this system's models (the models tracking it) are not confident in a consensus, with some going westward ho, and others moving towards the Gulf, and still others staying somewhat stationary.

We will keep you updated on all developments with this system as they come in.
