No doubt. Would be tragic. Clear west trend (as anybody could see at 48 hours).

Not a trend. It has been bouncing 50-75 miles between runs. Regardless....all the latest runs across the models are putting Miami in a very bad spot

Apacoliptic euro run. 

Another thing to remember from Katrina is the huge dome of water that's already moving with the core. So even if we do see this weaken down to cat 4. (I think that happens before another burst back to 5 before landfall) there is a cat 5 surge with this thing aimed at MIA. That and wave run up which caused most of the damage during sandy will mitigate the lack of shelf.

Certainly the worst fears are possible. I don't envy emergency management officials, the nhc, nws, or anyone who has to make a life or death decision to leave. It's crazy that the models are overall not that far apart but such small differences are so HUGE when it comes to impact and where. And It's scary to think about but we all know there are going to be a lot of people who stay behind and don't evac.

The euro is scary indeed but even the more east models show no room for error in se florida if you are hoping the eastern eyewall doesn't come ashore.

Still some time to go, but given the model clustering, it's becoming increasingly difficult to envision a way out for Florida.  And with this 12z Euro run, it's at the point where even a slight eastward adjustment would do nothing good for the eastern part of the state.

Disagree -- GFS went west. HWRF -- west. GEFS -- west. Euro -- West. Want to take "never makes Florida landfall" and I take the other side for a cold beer?

At this point west trends help mitigate damage - far lower population densities on FL Gulf Coast.

No, this run puts Miami in the RFQ along with FLL and PBI because the winds are out of the South and the mean motion is to the North, so that verbatim the greater Miami area would experience the highest possible winds. If Irma tracks a bit further West, you're still keeping Southeast Florida in the strongest quadrant, and now you're putting places like Tampa, Orlando and Sarasota in play that otherwise wouldn't be.

Also worrisome is the short term impacts. Can't help but think of the few days after Andrew when there was basically little law enforcement in certain areas, lack of water, etc. and a degree of lawlessness and a breakdown in civil order. I would NOT want to be in some devastated area and have to deal with THAT, let alone the long term implications.

The fact that we have the ECMWF and the GFS [and for that matter, the cmc] 72 hour forecasts projecting the eye of this likely cat4 (or worse) monster passing within 100 miles of downtown Miami is tbh completely terrifying. I haven't been on this board long, but I've been tracking TCs as a hobby since I was a kid (spurred by Andrew), and the nightmare scenario of cat4-5 aiming at south florida within 72 hours is now real.

euro shows a near due west motion starting over the next 24-48 a lot moreso than the gfs. wont have to wait long to see which one has a better handle. for now irma is slightly ne of the nhc track.

UKMET has had this for days and it wouldn't be the first time the UK led the way for the Euro (and ultimately the storm) on something like this.

This is wrong.  The Euro, verbatim, keeps MIA and FLL out of the strongest winds and dissipates much of the storms energy over the Keys and Everglades.  It would be a best case outcome for a S FL landfall.  Obviously a miss altogether is better still, but if it has to hit you want it to hit west.

Remember - most landfalls don't do that much damage, especially if there's no freshwater flooding.

If that happens I wonder what kind of weakening we will see before this thing gets to Orlando or the Space Coast.  Charlie even did a number on the Orlando area as a compact storm.   It's inland has quite a bit more trees and some older houses :( 

Unfortunately the Hurricane is huge at this point and is starting to take off as it hits the keys. The N/NE side has the highest winds. If there was another worst case scenario, besides riding up the coast, this would be it.
