South Florida needs that track to shift since they aren't remotely prepared  for a hurricane of this magnitude.

He talks about the worst case, and storm surge for Miami:

Quote

What, in your mind, is the worst-case scenario for a South Florida hurricane?

There are two kind of worst-case scenarios for Greater Miami-Fort Lauderdale. One is Hurricane Andrew coming ashore 10 to 12 miles farther north so that the destruction corridor includes South Beach, the Port of Miami, the banking district, the Miami International Airport, and the Coral Gables and Doral business districts. Besides the unimaginable destruction and widespread homelessness, it would be dagger to the economic heart of the region. Tourism and business would be incapacitated for an indeterminate length of time. With no jobs and housing, people would have to leave. It is impossible to imagine how the region would resurrect itself and how long it would take.

The other worst-case scenario is exactly the Great Miami Hurricane of 1926. Because of its size — covering all of Miami-Dade and Broward Counties — that storm would incapacitate the entire region of nearly 5 million people. The estimate is that damage would approach $200 billion.

In addition, there is a little-mentioned threat from a storm that generates a storm surge in the range of 10 feet along the oceanfront. Tens or hundreds of thousands of people would likely be stranded and immobile in their buildings after the storm. People staying in high-rise buildings would be safe, if they rode out the storm in a lower-level hallway. But the grounds and streets around the buildings within range of the storm surge would be deep in sand and debris — as happened in 1926. So people will be stuck in buildings with no power, no water, likely little or no communications, and no way to get out or get people in with supplies and aid for an extended time after the storm.

I think what you're talking about are the gravity waves.

18z GFS might have ticked East which is probably just noise and will wobble back and forth with every run. Takeaway for me isnt track but much deeper than past 4 runs in general MIA vicinity. 

Have to wounder if those skyscrapers will hold up against CAT5 winds.... Catastrophic run after run!

A wave cannot be higher than the water is deep. At about 80% of the water's depth the wave has no choice but to break. This is why large ocean waves never reach the coast. If you can get a good vantage point with good visibility you can even see "near shore" waves break on the horizon before reforming to become final beach breakers.

And that's why 100 feet rogue waves occur out at sea not near the shore.

This has been consensus for a day or two.  Scrape Miami and then target the southern most SC coast.

Euro and GFS seem to have this locked in now. Still some time to change but the consensus has grown for a major impact from Florida to the Carolinas
