As of Saturday morning, nothing has changed with the post below
The wind currents did exactly what I said they'd do overnight, and I don't see how Katia is just suddenly going to do a 90 degree turn. If it does, the wind map is obviously not how anyone decides where something will go. But it sure looks like Irma is going into the gulf now that Katia is gone.
PREDICTION: The death of Katia means Irma is going into the gulf
The global wind map tells the story. Once Katia made landfall, all the currents changed. All currents at all levels are now pushing Irma into the gulf. If that happens, Irma will then become the strongest hurricane ever recorded.
Could I be wrong? YEP. But when it comes to the weather, predictions are all there is, and it is not the same as making other types of predictions.
Ok, it is time for me to explain this wind map, which I have spent hours on by now, and figured out how to use well.
Keep it zoomed where this link has it. In the lower left hand corner, there is a button that says EARTH. Click it. This will open up a window that has several options. One of the options is height. The height option sets the level in the atmosphere (in millibars) where the winds are being measured. The first is sfc for surface, the next is 1000 millibars, which means about 400 feet up, the second is 850, which corresponds to about 5000 feet up, then 700 for about 10, 000 feet, 500 for about 18, 000 feet, 250 for about 32, 000 feet, and 70 for about 60, 000 feet. IN ALL CASES, AT ALL RELEVANT LEVELS, ALL WIND CURRENTS ARE PUSHING IRMA INTO THE GULF. If that's the case, where's Irma going to go? INTO THE GULF.
The trajectory cone keeps changing, directing Irma more towards the gulf. You can clearly see what I am talking about in the linked wind map, by following my instructions. There is no brick wall stopping Irma from entering the gulf if at all levels the wind is pushing it there, and it all changed when Katia bit the dust. Katia was producing a draft that was pushing Irma north. That draft is not there anymore. Irma will (probably) now, as a result of Katia making landfall, start heading due West. If that happens, WATCH OUT, it is going to be a hurricane freak show.
