She's going fishing. I'm not an expert, I've just been watching storms long enough to know that when models are shifting east this early, the trend usually keeps going east. In fact, it's probably going to be sunny and a little bit windy for the Carolinas and FL.

But with that said...I already stocked up on hurricane supplies LAST FRIDAY and I booked rooms at two different hotels for Monday-Tuesday and Tuesday-Thursday. Trying to cover all possible scenarios.

TIP: If you reserve a hotel through a third party site and you need to push the days back, you'll have to cancel the rooms and re-book which means that if the great unwashed masses are all booking rooms at this time, you're SOL. So just book multiple rooms for multiple days and then cancel the ones you don't need. Hopefully you don't need any of them.



Is there any science to back up your theory? What makes the models shift further to the east? How far? Remember Irma is over 400 miles wide.


None it looks like. A feeling. Sorry, not good enough with the empirical science gains we have made in the last few hundred of years LOL.

Fully aware this could take an eastern track -- but the other scenario is much more destructive and right now the NHC forecast. It's hard but sometimes we have to trust the experts.


I want to add, too, that with so many lives at stake, I cannot for the life of me, figure out what one gains by telling so many reading here that it's OK to sound the all clear at this point.

You could, literally, be dooming thousands to a very bad fate.

What does one hope to gain in doing this? Is it just the sense of "being right" about something? IDK

Still lots of time for it to change, figure we won't know direct impacts in our neck of the woods until Sat night/Sunday

Believe me, I am taking this storm very seriously since I literally live on an ECFL sandbar, but I thought maybe a little levity could help. This was posted in our local newspaper this morning. I'm sure Floridians can relate.

My heart and prayers are with the island nations currently experiencing this B*TCH and those that are in her path.

Or go to the NHC site and turn the Lat/Lon on the satellite loop.

NHC tends to keep high intensity longer in operational advisories for warning purpose. This happens often in landfalling weakening hurricanes. They may downgrade the intensities in post-season best track if no higher winds were found.

NHC didn't have data from the RFQ when the advisory went up, may lower slightly with the intermediate advisory.

Based on the recon data pass through the NE eyewall, I'd say this has weakened some to 165-170mph range; still a formidable and incredibly dangerous category 5.

Ok, one more time. This time for the stubborn or blockheads. Cuba disruption looks off the table today and Florida is most likely to take the full brunt of one of the strongest hurricanes. Don't think of your house as a person because it can be replaced. Look at being away from your for a few days as a vacation(less stress) and if everything turns out good then you come home and your home is still there and it survive the few days out of 365 this year without you. Worse case you have to repair the damage but you are alive to do so.. I'm no evacuation expert just my 2 cents.

Those were extrapolated values from the aircraft, the dropsonde actually measured 923 with 7 knots, which could translate to 922.

From the NHC:

An Air Force
reconnaissance aircraft that performed a single pass through the eye
this morning reported SFMR winds of 152 kt in the northwestern
eyewall around 12Z. Assuming there are stronger winds in the
northeastern eyewall, the initial intensity remains 160 kt for this
advisory. Another Air Force aircraft is currently entering the
storm.

still pretty much supports 180 to 185. they would wait for more passes before doing anything and especially a eyewall drop..

If this NHC track verified it would be a worst case scenario. Mia would deal with the N and S eyewall, while Ft Lauderdale and WPB metro area would see the NE/RFQ.

Has she been at 185mph the entire night as per NHC or has there been fluctuations in speed ?
