How many hours out did the Euro start to peg Harvey on the Texas coast consistently?

Which model did the best at predicting the landfall of Harvey? I live in SE Fl and the Euro is not favorable for us but the GFS makes me less nervous. I have been watching this page for so many years. Frances, Jean and Wilma were horrible but this storm could be even worse so it concerns me.

Not Cycloneye but I am in PR. IF there's one forecast I take seriously it's yours (long time time lurker).
We already started our preparations..

If I am not mistaken it is not officially a major yet, cat 2 as of now.

It's hard to compare Harvey to Irma. When the models were trying to nail down Harvey's track it wasn't very well formed yet. Irma is already well established so I would guess that the long range forecast track will be more reliable than what Harvey's was.

A major at 5 or 11 is almost a guarantee.

The bad part is that if Irma is doing an EWRC now, then the wind field will expand, and she will have plenty of time to strengthen more

I wouldn't be surprised if the run at cat 5 occurs after a 2nd Ewrc.

It would be lights out in PR and/or Hispanolia, too. A lot of people on both islands..

yeah and wsw to SW dips in track often are a result of the right conditions being present for that to happen... many examples.. but wilma and katrina come to mind..

Irma may have time to go through 2 complete EWRC cycles before reaching PR. Look at the moisture tap to the south and the inflow from that. This is key to growing a large hurricane in addition to the EWRC that will happen in the coming days.

Also Isabel when she got that perfectly round eye, although she never really took a wsw dip.

Looks like numbers have increased significantly... so seems highly possible IMO.

Ah thats the unknowable, it could end up having multiple EWRC one after another, equally it may have a couple of really rapid EWRC and you'd barely know its even happened, abit like Harvey.

NEW - WEATHER WATCH HURRICANE IRMA: Could Strengthen into an Extremely Dangerous Category 4 System

31 Aug 2017
Published in Soualiga News
:rarrow: http://www.soualiganewsday.com/local/so ... ystem.html

SINT MAARTEN/CARIBBEAN – The National Hurricane Center (NHC) out of Miami reported on Thursday that Hurricane Irma strengthened rapidly to a Category 2 system due to some weather elements in its current area.

Irma is expected to move over some cooler waters on Friday and further strengthening hopefully according to NHC will level off. Thereafter, over the weekend and into Monday, September 4, Irma will move over warmer waters which is expected to promote further strengthening of the hurricane making it an extremely dangerous Category 4 system East of the Caribbean island chain on Tuesday, September 5.

A high ridge weather system to the north of the hurricane will influence its track towards the Caribbean island keeping it moving westward towards the Leeward/Windward Islands. It’s still too far out and too early to say where exactly Irma will end up and how big the hurricane will be when it’s about 500 miles away from the islands.

Crown Weather said on Thursday that, “First and foremost, Irma is a MAJOR threat to the central and northern Lesser Antilles, Virgin Islands and Puerto Rico from Tuesday through Wednesday. The southward shifts in the forecast track by the European operational and European ensemble guidance are very worrisome as it is looking increasingly more likely that the core of a major hurricane will move directly over the northeastern Caribbean around Tuesday into Wednesday. Irma is a very serious threat to the central and northern Lesser Antilles, Virgin Islands and Puerto Rico.”

Crown Weather adds, “The islands I am most concerned with right now for a major hurricane impact are Guadeloupe, Antigua, Barbuda, St. Martin, Anguilla, the entire US & British Virgin Islands and Puerto Rico. Please monitor the progress of Irma extremely closely and it may be a good idea to go through your hurricane prep kit and be prepared for a major hurricane impact.”

Now is a good time to review your hurricane preparatory kit.
