Both Irene and Irma were used before the establishment of current lists in 1979: Irene in 1959 and 1971 and Irma in 1978. And yes, I know the lists are reused every 6 years in the Atlantic and Eastern Pacific (out to -140°). Other basins just continue through a long list, and when they reach the end of the list they start over again and thus no Greek letters are used, such as in the Western Pacific (with Guchol being named today only 5 names remain before getting back to the start).
Supporter of the construction of several running gags, including I-366 with a speed limit of 85 mph (137 km/h) and the Hypotenuse.

Please note that I may mention "invalid" FM channels, i.e. ending in an even number or down to 87.5. These are valid in Europe.

Latest track shifted Irma to hit Miami, then go back offshore before land-falling somewhere along the southeast Atlantic coastline from Georgia to North Carolina

That's exactly right, a double landfall. More specifically, Miami and points south should be prepared for landfall of a ridiculously strong cat 5 hurricane (the model average is a strong cat 4, but 5 is very possible and should be the focus of preparations. Irma has outperformed her forecasters' predictions for a couple days now). Much of Florida's eastern coastline may be spared a direct hit but instead take a long ride through the western half of the storm after it re-enters the Atlantic Ocean north of Miami. Coastal Georgia and South Carolina, particularly from Savannah to Charleston, should be prepared for a cat 3 or 4 landfall.

Oh, lovely. Just checked the NHC track and Irma's projected to exit Florida right where I live (Brevard County). Lovely.

The track I saw showed the eye passing more or less right over my brother-in-law's area of Broward County and then the storm exiting near my sister-in-law's area in Brevard.

Brevard County has just ordered a mandatory evacuation of the beaches and Merritt Island, starting at 3 PM Friday. The latest track shows Irma passing right over KSC. (I live 15 miles west of KSC).

The NHC forecast shows landfall near Miami as a cat 4. Why? I've seen several TV meteorologists say they think it will be a 5, and on the Weather Channel they keep showing the water temperature map, which clearly indicates warmer water off the southern coast of Florida than what Irma is presently churning through in the Atlantic. The NHC track doesn't put the storm over any major land masses before Florida, and there's all that hot water off the Florida coast. I can't imagine what they're thinking is gonna weaken this monster.

Other forces are at play. Namely, the front that is causing Irma to turn north in the first place.

There may be some effect from interaction with land.  It's been over tiny islands but is now closer to Hispaniola and, soon, Cuba.  That disrupts the wind pattern, which may weaken it.  As long as the eye and most of the core remain over water the effect should be fairly small.  The forecast shows gradual weakening.  In addition to interaction with land, there's the cold front that was mentioned.  That will likely come along with less upper-level outflow and more shear.  Also, when that cold front is approaching there may be some dry air intrusion.  A hurricane is a precision machine.  Many components can contribute to or detract from a storm's intensity.

Yeah, that must be it. I suppose it would do so with an influx of dry air? Meteorologists are not entirely in agreement about whether that front will weaken the storm much. Some don't think it will be enough to counteract the hot water that surrounds Florida, and so they say that if it does anything at all it will strengthen before landfall. I've also heard the idea that the front won't approach fast enough to impact Irma all that much. She'd still turn north because the general trend is toward the poles, and she's gonna turn that way as soon as the strong Bermuda high will allow it. I have no formal knowledge of the subject, but as an interested layman it makes less sense to me that it might weaken.

Yeah, while our forecasts are not quite so precise, haha. The models have always done a better job of forecasting a storm's path than they've done of forecasting its intensity.

More than likely, the incoming trough that'll help direct Irma will also bring in a bit of shear which hurricanes do not like hence the slight weakening to a cat 4 possibly. Reason why Irma has thrived as a 170-185 mph storm is the lack of shear.

Best wishes to everyone in Irma's path! It looks like, according to the latest model runs, that the storm will go right up the peninsula from the Keys up to the Georgia line and beyond. And as I was saying in another forum I belong to, if Irma should want to blast through Orlando (with all its tourist attractions such as Disney World), Tinkerbell could sprinkle all the pixie dust in the world; it ain't gonna do a damn bit of good.

And Katia just hit Mexico as a cat 2. Mexico just had that 8.4 magnitude earthquake so not looking good for them either.

The latest forecast track says Key West, Naples and Tampa could all see the eye of cat 5 Irma. On TV they said that Key West High School is filled to capacity with evacuees, yet emergency management experts are saying the high school may not be safe. A few days ago I said that in the end Irma might make Harvey seem tame by comparison, and the storm still seems to have that potential. I'm happy to say that the several people I know who live in South Florida have either left the state or evacuated to Orlando.


DeaconG

Yes, that track shifting west just enough to get Irma off from over me...but my extended family in the Tampa metro area are about to have issues. I'm looking at tropical storm winds by Monday versus Cat 3 several days ago.

The 11:00 update for Irma's track showed it had turned somewhat directly to the north. Looks like a direct track towards the area of Fort Myers where our relatives live. They won't be going anywhere any time soon because the one road that leads in and out of their neighborhood (Briarcliff Road) will surely flood. It floods during ordinary thunderstorms.

I'm not sure whether to applaud our relatives staying in Fort Myers. But I'm chuffed they're OK so far (21:11 Sunday).....

QuoteWe feel we are safe - and made it! Some trees and screens that we can see, street is flooded but just at end of driveway here so hopefully won't be an issue - storm surge is still to come so we won't know till later or tomorrow about mom and dads. Thank you for all the prayers and support we'll continue to send updates when the sunshines! ❤️

Her parents live closer to the coast and flooding was a serious worry.
