jasons Posted September 7, 2017 Share Posted September 7, 2017 Miami-Dade has a huge number of structures built before those building codes were in place. There's a lot of apartment complexes that are practically falling apart, especially in low-income areas. Not to mention all the high-rises. The skyline today is nothing like it was in 1992.

The nearby continental shelf and deepwater give the water pushed around by Irma somewhere to go. The biggest concern for surge will be on the barrier islands and along the Miami River. This will primarily be a wind event for Miami proper. The Georgia/SC Lowcountry is much more vulnerable to the water pushed around by a 3-day Cat 5 storm. Water is absolutely a concern for MIA. The city floods with a few inches of rain, and Irma will inundate the area, and surge will also be a factor. Peeps should refer to NHC and local forecast office discussions and public statements.

jpeters3 Posted September 7, 2017 Share Posted September 7, 2017 2 minutes ago, Buddy1987 said: Question for you guys. With those intense cloud tops expanding and exploding around the western and northwestern portion of the eyewall, wouldn't that be a signification that it is showing signs of wanting to strengthen again? I am assuming whatever shear it experienced earlier has relaxed, along with the bath water it is about to encounter, some strengthening is definitely possible correct? Or am I completely off here? The expansion looks somewhat minimal to me. There hasn't been a substantive enough change in the IR appearance since this morning to suggest strengthening. If anything, cloud tops have warmed slightly. Anyway, lets wait for the next recon pass or major changes to make the "strengthening" or "weakening" calls.

adiabatic13 Posted September 7, 2017 Share Posted September 7, 2017 cooling cloud tops at the time of the usual diurnal minimum are indicative of intensification, at least historically in every other Atl hurricane that has exhibited the same behavior...it's possible she's steady state, though at her current intensity I suppose it doesn't much matter sensible weather-wise...there's sufficient of recon to verify any structural changes, so I'll delete those intensification posts Link to comment Share on other sites More sharing options...
NJwx85 Posted September 7, 2017 Author Share Posted September 7, 2017 With the slight shift West on the 12z HWRF, it's now close to the worse case scenario. It's a tick West of the 12z GFS. Outstanding consensus now for a track from Miami-Dade to Palm Beach County and then offshore somewhere around Palm Bay or Melbourne. Link to comment Share on other sites More sharing options...
40/70 Benchmark Posted September 7, 2017 Share Posted September 7, 2017 26 minutes ago, Roger Smith said: Not sure if it was mentioned earlier in this long thread, but 12z GGEM also has the track inland over s.e. FL and the 12z Sunday position is roughly 25 miles west of MIA. From there it slowly emerges back over Atlantic near Cape Canaveral and makes a Monday landfall in western SC. The intensity depictions are clearly too conservative, from the upper component and past experience with GGEM, would estimate high end cat-4 landfall in s.e. FL, cat-2 east of JAX minimal cat-3 before cat-2 landfall in w SC. The Euro-GGEM similarity is not a good sign for Florida.

Agreed on the more considerable impact to GA/SC lowcountry, no question My point was that even though the building codes along So. Fla coast line are quite protective, there are other dangers from this storm that should not be ignored - with a ground surface elevation of 3-5 feet above mean sea level in greater Miami and a potential storm surge of 15-20 feet, one needs to be cognizant of the strong potential for storm surge flooding, because a surge of that nature will get into the city regardless of your shelf configuration Link to comment Share on other sites More sharing options...

The big danger will come from being trapped with rising water while sustained winds are around 120 mph, and no chance of rescue for at least 12-18 hours. Edit - wanted to add that storm surge will be an enormous problem south of Miami proper. Link to comment Share on other sites More sharing options...

bdgwx Posted September 7, 2017 Share Posted September 7, 2017 You'll have to pardon me if this was already posted. Sometimes it's hard to follow along with the banter. Anyway, here is the 12Z GEFS mean at 72 hours right at landfall. Now that we're getting to the D3 lead times we can probably start fine turning the track. There's still below average confidence in the track due to the timing of the turn, but obviously the GEFS track is...umm...not the most desirable for Miami.

Also, Andrew wasn't a Cat 5 for a week before landfall moving across the Caribbean coming in from a south/south eastern angle. That surge has had plenty of time to build.

Wind doesn't stop instantaneously. You would need a yield similar to that of the Czar Bomba , 50 megatons, to "disrupt" the circulation. All the fall out would be spread through the atmosphere at a super accelerated rate.

But, in my defense, I just don't want this turning into a media bashing thread when they were just quoting the mayor of a town down in FL. On another note that isn't banter related, at what time is it expected for Irma to start heading into the very warm waters? Link to comment Share on other sites More sharing options...
