I watched John Hope discuss Andrew in legendary fashion. I just couldnt stop watching the videos over and over because I had this weird feeling that months later a Category 5 hurricane would be staring down South Florida and as we all know, Irma threatened South Florida as a Cat 5 and that brought flashbacks to me having this funny feeling 5 months before Irma hit. Luckily, SE Florida dodged a major bullet but my gut was right...something was gonna come for South Florida.

Fast forward to 2020, and I developed another one of those gut feelings. This time, I am constantly drawn to Hurricane Wilma and Hurricane Irene (1999) videos on Youtube. I cant stop watching them. I have this deep feeling in my gut that Florida will get hit this year from a big hurricane coming from the SW Caribbean.

Maybe I am just being silly, but my gut feeling was right in 2017 and I fear it may be right again in 2020. The pattern and atmosphere just seem to be screaming for a FL hit from the Caribbean this year

Interesting WeatherEmperor. If we do manage to get hit this year I really think it would be from a Caribbean system recurving through Florida maybe in October or late September. For some reason I don’t have that feeling we will get hit this year. I did not have a good feeling about 2017 though. I see a busy season but no direct hits for South Florida from any hurricanes. I see a lot of recurving hurricanes east of the islands and the US and some west runners in the Caribbean impacting Central America, the Yucatán and the GOM.


Thing is, it takes a lot to "go right" for a storm to hit South Florida. SFL is kind of protected by Cuba and the Caribbean islands which weaken anything that come through it, and then you have the Bahamas in front of FL which typically take the brunt of storms recurving away from FL. South Florida is a bit tricky for a storm, even look at Irma.


That's mostly a false sense of security, some of the most intense hurricanes that have hit S FL have tracked over Cuba and the Bahamas, have re-intensified quickly before striking FL. Good example is Charlie in 2004.
The exceptions like Irma that moved very slowly over the coast of northern Cuba, if not stalled for a few hours, causing it to weaken. Other storms that have moved right over the Island of Cuba almost on its entire length have definitely weakened before hitting FL. Their track over the greater Antilles will definitely dictate what strength they are before hitting FL.
A majority of the MHs that have hit SE FL have tracked over the Bahamas first and did not weakened them much if any because of their flat stip topography.

From the central Caribbean to the SAHAL area is almost one continues cloud of dust this morning.

Yes Orlando, West Palm Beach, Fort Lauderdale, and Miami metropolitan areas really lucked out over the past four seasons when it came to Matthew, Irma, and Dorian. Though Miami got some decent storm surge from Irma. One of these days our luck will run out!


Orlando? I would put Tampa way before Orlando which is protected inland. Tampa Bay is way overdue for a MH, 99 years since last hit, if hit directly from the SW the storm surge will be catastrophic, it is estimated that over a hundred thousand homes would flood from the storm surge.

I was referring to metropolitan areas that did not receive sustained hurricane-force winds over the past four seasons with Matthew, Irma, or Dorian. Yes I too believe Tampa/St. Petersburg is way overdue for something significant. Storm surge would be insane if something were to come in between Clearwater and St. Petersburg.

There are good discussions about the Bermuda High and here is one more nugget to add.

Very little recurves.
Pretty much on track so far.

The NAO is forecast to go negative next week. Will it stay negative or will it go positive in the future? Something to think about as we discuss stearing patterns later in the season

During the past month it has not been performing too well on both sides and over all it turnes to be near neutral.

Not sure what Webb is trying to insinuate here. Is it that he doesn't believe the West bast Atlantic basin track pattern because of this emerging modeled move away from a +IOD?

This is coming from a VERY good source on potentially hyperactive season.

Sure seems like it, at least in recent times. Of course, such hits were brutally common from 1920s-1950.

I think that if we'd had more hurricane activity between 1950 (King) and 1992 (Andrew), Miami and the rest of South Florida would not be what it is today. IMO......a lot of the population and economic growth of Southeast Florida has been made possible by a half-century of no-hits, and in some cases just brushes from stronger storms. Betsy and Donna were significant, but not true threats given their landfall locations in the upper and middle Keys. Cleo was a cat 1 and nothing even 1964 Miami couldn't handle. Yet after Betsy, we went almost 30 years before even sniffing a hurricane. No coincidence a lot of our explosive growth happened in the 70s and 80s....there was nothing but a mild scare from David.

Cat 5 Irma was an existential threat to the entire tri-country metro area, and especially Miami proper had it taken that nightmare 880mb GFS track right up the gut. Some of the newer post-Andrew condo buildings may have survived that, but not a whole lot else would have. More than likely, millions of us would have been forced to seek out a new life elsewhere. We owe Cuba one for that, big time.

I think modern Miami is about as well-equipped as it can be to take on a major hurricane, but not an 880mb 195-205mph storm.

Oh yeah, I remember Irma’s <900 mbar GFS runs. Wasn’t there something about the possibility of it reaching ~200 mph if it went over the extremely warm waters of the Florida straights instead of making landfall in Cuba?

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

They're also mentioning that the high pressure pattern is a little further north than previous years.. anyone get that? and if so, let's discuss what that could mean.

That is probably one of the biggest SAL outbreaks I've seen since registering to this forum. Looks like no end in sight either since stronger SAL is still coming off Africa.
