She'll be cat 5 then, as still plenty of time for intensification, and I doubt that will slow down.

Think you could be right

[Gray-Wolf]

If we are seeing EWRC then there WILL be further intensification once complete & Cat 5 is not out of the Question (IMHO?)

Thanks, it's a bit of a bug-bear with me when acronyms are used without an explainer against them.

No, there will not be enough time for the core to consolidate and retighten back up, however the existing wind field will get pushed outward.

Surge about to get a lot worse

Quite a coincidence that on this day 2005 Katrina made its second landfall as a cat 3.

[MAF]

Full landfall expect in the next hour. 1300BST

Just back down to a Cat 3 as it makes landfall, due to the EWRC taking place.

A built has been dodged due to the timing of that. Would have been much stronger, but still going be bad re strong winds and storm surge.

Really no difference between a strong Cat 3 and weak Cat 4 tbh

True but without the EWRC we'd probably be looking at strong Cat 4, maybe even Cat 5. This is what happened with Charley and Michael, which were able to strengthen all the way up to landfall.

Most damage from hurricanes in Florida comes from the flooding (with a few exceptions.) The big concern here is the storm surge in in apalachee bay which doesn’t have a recorded historical precedent. My understanding is that the area is quite rural which might lessen human impacts in that regards.

Landfall made at 12:52BST NHC confirm,

According to the National Weather Service, Idalia's landfall took place near the town of Keaton Beach, in Florida's Big Bend area, at around 0745 local time (1245 BST).

The service warned that Idalia - now a Category 3 storm - has struck with maximum sustained wind speeds of 125 mph (201 kph). (BBC)

The last 15 minutes of this looks quite bad.

Quite a bit of damage https://www.webcamtaxi.com/en/usa/florida/fortmyersbeachpier.html

My first ever shot at an eye landfall Forecast I'm extremely chuffed with this especially at 2 plus days out as Idalia was yet to develop

Cat 1 now

I disagree. As wind speed increase the force on buildings and objects increases by three times. So it's exponential. Even a 25mph increase means it can be nearly 75% more force being applied against buildings etc. 

Additionally as wind speed increases suction on the leeward side of structures increases, so you can get sides of buildings pulled out if they are not up to hurricane standard.

What may stand up to a Cat 3, may not in even a weak Cat 4.

What was the highest gust recorded in Florida today? I checked meteologix in the Florida and Georgia region. No stations where she made landfall. The highest gust I saw was 66mph from the limited amount of stations.

Much like the hurricana itself this thread has gone from cat 4 to tropical storm. No posts in ages

It seems Idalia is coming towards Franklin with the remnants of Gert and a newly formed storm of Jose are getting close to each other. Don't know if there is going to be a Fujiwhara Effect between any of those storms?
