Much appreciate your FWIW... the "gusts" you mention are much more in line with my expectations of "gusts". I'll be more careful and double check what I "think" I'm seeing before I post. Still praying for something unexpected to occur to knock her block off before SO FL approach. Peace Link to comment Share on other sites More sharing options...

Simple enough, but the southeast Florida pass can be further simplified to the first part of what you originally stated, which is quoted above. To say it slightly differently, the further south track has a more west component so it travels further west over the same amount of time and feels the trough--which is coming in from the north--later. As a result she recurves later and makes LF in/near Miami. The GEFS clusters clearly show this as well. Gven the euro's far superior verification scores for the short term track thus far, I'm hedging strongly in favor of a LF in southeast Fla. and won't begin to question this forecast until/if Irma's short term movement deviates notably north of the 0z euro's track over the next 48 hrs.

Even though the model spread amongst the 4 major global models (Euro, UK, CMC, and GFS) was more than it was at 12Z, given that the Euro solution didn't really change from 12Z to 0Z, maintaining that probably catastrophic track right up the SE FL coast, and given the superior Euro verification scores in the 3-4 day timeframe, I'm thinking there's no way the NHC changes their forecast track at 5 am. i..e., that's a long way of saying I agree with you, lol.

mempho Posted September 7, 2017 Share Posted September 7, 2017 I'm somewhat surprised that they didn't go with a hurricane watch on the SE FL coast in the last package. I know it would be early but I was sort of expecting the NHC to go with extra lead time. Sent from my SM-G950U using Tapatalk Link to comment Share on other sites More sharing options...
Snowman99 Posted September 7, 2017 Share Posted September 7, 2017 Eh..6 hours isn't that much of a difference at this rate. They'll be issued late this morning. Everyone knows they're coming, a lot of people are already leaving. NHC usually does everything by the book. Link to comment Share on other sites More sharing options...

This is what BBC said: "The Dutch navy has posted a video taken from a helicopter above Saint Martin which shows widespread damage on the island.They also said that the island's airport is unreachable, and they are prioritising deliveries of help and supplies.Saint Martin is divided between the Netherlands and France."

lakeeffectkid383 Posted September 7, 2017 Share Posted September 7, 2017 Did anyone else notice the NHC finally dropped down Irma's wind speeds at the 5am advisory...? Down to 180mph lol. Link to comment Share on other sites More sharing options...
Random Chaos Posted September 7, 2017 Share Posted September 7, 2017 I did notice. IR showed the eye briefly occluding, and 248nm radar shows an inner/outer eyewall. I suspect the poor eye appearance is due to an ERC. Storm is probably weaker than 180mph, but with the ERC several hours in and the eye clearing, should be strengthening again. I suspect we will see it back to 185mph sometime during this morning's recon. Link to comment Share on other sites More sharing options...

delijoe Posted September 7, 2017 Share Posted September 7, 2017 I don't get it.... 0z Monday on the Euro the center is over Vero Beach. On the GFS it's about 100 miles ENE of that. Shouldn't these models be in closer agreement this close in... Looks like landfall around Charleston, SC on the GFS Link to comment Share on other sites More sharing options...

I'd say that's fair agreement in all honesty given the complexity. The eventual location will be dependent on track to that area and then the shape, location, and strength of the trough over the NE.

The problem is this 100 miles is the difference between total devastation of the Florida east coast and dodging a bullet. If the eyewall misses the coast it'll make a huge difference in damage and lives... and hopefully before it reaches SC it weakens enough that it won't be nearly as devastating...

You cannot expect better agreement given the complexity. Both sets of solutions (and others) are possible given the players on the field. You may not know if it'll hit MIA until it does or does not. Unfortunately, planning for Irma will be a PITA. Link to comment Share on other sites More sharing options...

CoastalWx Posted September 7, 2017 Share Posted September 7, 2017 You guys need to take it easy, on some of the posters asking questions. It's OK to ask questions if someone does not know. Yes it is perfectly natural, for 100 mile differences to occur in models when you are four or five days out. Link to comment Share on other sites More sharing options...

TPAwx Posted September 7, 2017 Share Posted September 7, 2017 The Euro, along with the GEFS, should be enough to convince official/people in Miami Dade to accelerate evac protocols. Very tough around and up to say Ft Myers, which is still east of the projected track but it won't take much of a shift to spell disaster for those areas. Not sure about other areas but here in Tampa gas stations are low or out. It's going to be sheer panic if the Euro or GFS shift West and cause the NHC to adjust the track significantly.

TPAwx Posted September 7, 2017 Share Posted September 7, 2017 The motion portion of the NHC 5am discussion gives a good sense of the upcoming dilemma. Weighting Euro at this point. The initial motion is 290/15. The hurricane is currently being steered by the subtropical ridge to the north, and for the next 48 h or so this motion is expected to continue with a decrease in the forward speed. After 48 h, a mid- to upper-level trough digging into the eastern United States is expected to create a break in the ridge and allow Irma to turn northward. The timing of the turn is the most important question and one still filled with uncertainty. The UKMET, UK Ensemble mean, and the NAViGEM are the models showing the latest turn, and they forecast Irma to move into the southeastern Gulf of Mexico and near the west coast of the Florida Peninsula. The ECMWF and ECMWF Ensemble mean are in the middle of the model pack and show Irma moving over the southeastern portion of the Florida Peninsula. The GFS, Canadian, and GFS Ensemble mean show the earliest turn and show Irma moving east of the coast of Florida toward the southeastern United States. The new forecast track will best follow the ECMWF, as well as the Florida State Superensemble and the HFIP Corrected Consensus, and it calls for the center to move over portions of the southeastern Florida Peninsula between 72-96 h and then across the Atlantic into southern South Carolina by 120 h. Users are again reminded not to focus on the exact track since the average NHC track errors at days 3, 4, and 5 are about 120, 175, and 225 miles, respectively.
