Thankfully Jamaica did not get the bad part of the hurricane however torrential rains for another 12 hours will cause flooding and mudslides but they dodged the worse.

Rapid intensification, just like Charley. Holy crap. O_O

Rapid Intensification is a decrease in pressure at a RATE of 44MB/day for at least 24 hours.

Not quite there yet.

If that is true then Charley did not RI. I believe it should be 20 millibars for 24 hours.

Which is
10 millibars per 12 hours
5 millibars per 6 hours
2.5 millibars per 3 hours
1.25 milibars per 90 minutes.

His winds increased from 90 to 130 MPH ALREADY???

That's what the NW Carribean does for you.

Does it also help you lose weight??? :lol:

I know it was anitcipated that he would become a cat 3, but not until he reaches the Gulf. Hopefully, as he goes over Cuba he'll weaken. I'm praying for those poor people there right now.

According to this site, RI is *42* MB/day (I was wrong, I said 44 :O )rate decrease over 12 hours. Not too sure how "official" that reading is, but another site claims RI to be 30kt increase/day is the onset of RI.

So either it has, or it hasn't undergone rapid intensification, depends on who you ask. /shrugs

This thing has went from a 75 mph hurricane to 130 mph hurricane. In 24 to 25 hours. That 55 mph increase.

Thats is bombing.

Thats like a hurricane heading for land going from let say.
90 mph cat1 to 145 mph cat4 hurricane...

Going fromn 75 to 130 makes me a little nervous.. Makes me wonder what it'll be when it slams into Fla/Alabama whatever..

wow 6 hours ago the SHIPS model projected 130mph winds in 48 hours... hmmm well it happened 36 hours sooner...

Dennis is actually lookin pretty good for being squeezed between two landmasses.

Some of the definitions that the NHC uses regarding hurricane intensification are so vague that they are infuriating.

Examples:

Explosive Deepening:

A decrease in the minimum sea-level pressure of a tropical cyclone of 2.5 mb/hr for at least 12 hours or 5 mb/hr for at least six hours.

So does that mean that since a hurricane pressure drops by 33 mb in six hours that it isn't explosive? And why is it that a 30 mb drop in six hours, or a 30 mb drop in 12 hours represents the same thing? Isn't just a little more sane to say this if the pressure drops 30 mb or more in 12 hours or less that it represents explosive deepening? Why make something simple more complicated?

Rapid Deepening

A decrease in the minimum sea-level pressure of a tropical cyclone of 1.75 mb/hr or 42 mb for 24 hours.

So are you saying that if the hurricane pressure drops 6 mb in three hours it is rapid deepening? That's more than 1.75 mb/hr. Or do you mean that the pressure has to drop 42 mb in 24 hours or less? What's with the 1.75 mb/hr OR 42 mb for 24 hours? Again, can't you speak English? We don't understand gobbledy-gook so well...

SHIPS model now projecting 141 mph winds in 24 hours before weakening over Cuba... Im not so sure... I dont doubt that Dennis will reach 141mph... probably higher even... but first, I wouldnt be suprised to see Dennis at 141mph tomorrow morning, and second, judging by the track Dennis is taking on satellite (plus the continued track of NW said by the NHC) I would say Dennis will be over Cuba by the 11am update tomorrow

This is probably the best I've seen Dennis so far!

Thats looks like we got a cat4 hurricane about ready to make its first landfall. How many people live there?

I bet Cat5 doesn't seem quite so far fetched now, does it? :eek:

My biggest fear is that Dennis will be one of those unstoppable hurricanes.Intensifying to strong cat 4-cat 5 before a US hit

(shades of Andrew) :eek:
