The Americans are regularly observing Ivan with the Hurricane Hunter aircraft. They fly into the eye and by finding the 700hpa height they can get an accurate fix on surface pressure.

Yes, I thought that one got down to 895hpa. It lingered east of Vanuatu for a few days.

Latest on Ivan is a central pressure 917hpa, sustained winds 140kts, Cat5.

Metars from Kingston, Jamaica.

The last time 3 hurricanes affected Florida in one season was 1964.

Ivan may still be a cat4 when it reaches southern Florida.

I dont think we should wish this sort of thing on anyone, Stormchaser. :( This forum is about enjoying weather, not being pleased that some people suffer by it.

i think you keep taking things out of context Tony
yes, this is a weather forum....and so a big powerfull Hurricane making a direct hit on a tropical island is interesting weather wise becuase then we will be able to see the power of that hurricane by the destruction it leaves behind....and watch the weather reports unfold...if people want to live in the caribean, then they are obviously used to hurricanes, and need to be ready to get one at some time....
it would be great for them if they always steered around every island...but that does not happen...
same for florida...they have goten to be a bit lax....its been a bit of a wake up call for them too...

but i dont and i dont think stormchaser03 does either wants people to die and property to be be destroyed....but if you live in an area that gets hurricanes then thats the risk you take.....you cant stop a hurricane...

just my thoughts

Sorry about the miss understanding!

Having an interest in stormchasing/watching and an extra interest in Hurricanes, Ivan reaching land on floridas coast and in the tropics provides us with that extra amount of information available on the net. It also shows us natures force that we would not be able to other wise see should it bypass land. 3 Hurricanes in a row is unfortunate and I am in no way 'wishing this sort of thing on anybody' or that Im 'pleased that some people suffer by it' How you manage to take that angle I dont know!


Imagine how much meteorological knowledge we wouldn't have now if we couldn't view material considered insensitive to any victims of a weather event-Gary Roberts

Looks like the power has gone in Jamaica. Surface obs plus radar have not been updated the last couple of hours. Damn. Just when the weather was going to get interesting. :(

You see, 03 isn't a totally mean bugger! He's just like all of us! ;)

Remember that one? Maybe it might play some relevance here…

Of course John didn’t wish harm on the people affected but from a meteorological and storm chasers point of view, “nobody got it on tape!”.

03, maybe best not to write "How you manage to take that angle I dont know!", because it can be taken that way even if you didn't mean it. We are all weather on this forum. People getting hurt is not what we, you or me want!

Lets end it there, back to weather!!!

Sorry about the miss understanding!

Hurricanes are most interesting when they are causing destruction and chaos. If Ivan was out in the middle of the Atlantic we wouldn't be so interested.

2.15pm today. looking real intense.

The elongation of Ivan is due to the hurricane running up against an upper ridge just the north. Looks like Ivan might pass just under Jamaica.
Jamaica has terrain upto about 2000m, it will be interesting to see what impact this has.
