Can you define "lightning speed"...I'm not seeing that. I do see plenty of solutions...some of which are very strong. If a system organizes it can intensify very rapidly if the stars align. OHC in the Gulf and Caribbean is record highs for this date per McNoldy's data. Otis went from a cat 1 to a 5 in 12 hours last year with similar rocket fuel. Explosive development should be a consideration even if that outcome isn't most likely.


I just go by where the models are showing the system every 6 hours. Also remember this system initially didn't suppose to hit land until next Sunday or Monday and now it's showing late Thursday and Friday. That's quite a difference in speed. I mean to get from where it is right now to the north gulf coast in only 4 and 1/2 to 5 days can only happen with a very quick mover. And that's also probably why the other models are keeping it much weaker than the GFS.


Yes according to the models this should be moving pretty quick once it turns to the northeast. Seems to happen a lot with these storms that approach Florida from the SW. Frances felt like it went on forever but Wilma was just a horrifying couple of hours.

Michael’s first forecast had a 60 kt peak at landfall. Obviously that was grossly underestimated and ended up being 80 kt too low.



Never use Michael as a comparison to other storms. In my opinion, Michael was a one off anomaly. A quirk if you will :)


No, given the changes in climate Michael is more of a glimpse into the future than a fluke.

GFS not like the others.



Thanks Steve for highlighting this!

Since it won't have time to get to an ERC, the trough could ventilate the storm and the storm will be moving too fast for upwelling, I think a storm that is RI'ing like the GFS is VERY reasonable right up to landfall.

It can happen in situations but this would be a big score for the GFS if it does. I wouldn’t bet on anything near 930’s yet.

Very bizarre this isn't an invest yet, when we're at 40/80 and near universal model support for tropical storm winds impacting land in less than 72 hours

Looks like 12z GFS and ECMWF both landfall about 0z or 7 pm Thursday evening within 40-50 miles of each other (Panama to Apalachicola).

Thanks Steve for the break down. So close to Pensacola to not be nervous but being just on the west side would be good for Metro P'cola. I just don't like the North then NW turn. Gonna be tight

It has been sent to my inbox two threads that were above this one in posts so this thread has not broken record of most posts in pre invest status. It was in 2010 with pre Nicole and pre Danielle. Thanks to Ubuntwo for sharing the links to those threads.
