![]() To borrow that well-traveled title. The electricity is back on! My area was in the first ten percent restored. There's something 3 million South Florida residents without power would like to say to the National Hurricane Center. Getting the track right is NOT a successful effort when the intensity is completely botched. I don't care how many qualifying statements or disclaimers they made. During the critical time period, about two days before landfall, when the decisions are made on what to expect. They were telling us the shear would weaken it to a cat 1, then weaken further after landfall. To us down here in Florida a poorly organized cat 1 that is dissipating is no big deal. Barely miss a day or two of work. But a TWO HUNDRED AND FIFTY MILE WIDE Category 3 is something entirely completely.... a couple order of magnitudes.... BIGGER. We were only one category away from a hundred billion dollar catastrophe. Everyone down here was completely taken by surprise on the intensity and especially the scale of this storm. There's another thing I'd like to say to the NHC. I know their political leaders disdain any talk of global warming. But there's an important trend that must be discussed even if it leads to their taboo subject. Wilma was a super-massive vortex. Last year saw an unprecedented number of land-falling hurricanes. No one could imagine a season worse, as last year saw about as many hurricanes as you can fit into one season. But all that energy has to go somewhere so the hurricanes are simply getting BIGGER in size. Forget the intensity for now, they are growing larger in scale. Much larger. We saw the incredible size of Katrina when it was a cat 5 in the gulf. And now Wilma. The large size of the eye usually indicates a weak hurricane, as they strengthen the eye tightens. So the NHC sees the large eye which shouldn't have time to tighten before landfall. And with the shear of the turn all computer projections show weakening. Wrong. It spun up without the eye tightening much.. That NEVER happens. It had an eye half the size of the Montana for chrissakes. This is an unprecedented and significant change in hurricane behavior. It's almost hundred mile wide southern stream of air feeding the vortex was a most impressive event to witness. You could almost set your watch by the timing of the lulls and explosive gusts. It had a symmetry and mass to it that boggles the imagination. For crying out loud the gusts literally shook the ground. No kidding, the ground was swaying back and forth under my feet. But the NHC will not want to talk about it. Why? Because someone might then ask why are they bigger. Their 20 year hurricane cycle won't explain it, were they bigger the last few cycles? Being near a peak solar cycle won't fully explain it either. We've had both those cycles operating for ages. But if you add a new variable, global warming, on top of those other two causes, then you get a more complete answer. So the NHC won't go down that road since it leads to somewhere their political leaders wish to avoid. Meanwhile, the NHC pops a few corks over their accurate track, while completely missing the true story. Jonathan s |
