Why Irma will turn North and not go into the Gulf

Posted: Updated:

The cold front that moved through Acadiana early this morning will continue to drift south into the Gulf of Mexico later this week.

Behind this front we will see an usually early strong shot of cool and dry air move over much of the southeast United States and into the Gulf.

Not only will this front bring us a nice taste of fall-like weather, it will be a big factor in why Irma will eventually turn up the east coast of Florida.

Strong hurricanes like Irma need warm, moist air to continue to fuel them.

Thus as Irma heads towards Cuba and south Florida later this week it will begin to run into the cool, dry air that will be located in the Gulf. 

As this happens Irma will not want to head for these less favorable conditions but rather turn back to the north to stay over the warm and humid environment located on the east coast of Florida.

It is for this reason that the latest forecast track from the National Hurricane Center and most models now project Irma to make the hard turn to the north and make landfall near Miami this weekend as a strong category 4 hurricane.

Irma should then begin to slowly weaken as it continues up the east coast of Florida and heads for Georgia and the Carolinas early next week.
