This may be a bit hard to read, but here is a storm surge map for the Tampa Bay area:

- Ocho Rios still blowing
Date: Sat, 11 Sep 2004 02:57:07 -0500

It is almost 3 am and Ivan is still howling out there. We have lost about 8
trees in our yard and from the reports on the radio, the worst is yet to
come. With the eye passing further south than predicted, we will be spared
some of the strongest winds. Give Thanks!

A lot of people have lost their homes, although I have not heard of any
casualties. Please keep all of us in your thoughts and prayers and we
weather this storm tonight.

- Ivan the terrible

Date: Sat, 11 Sep 2004 00:43:24 -0500 (Eastern Standard Time)

Ok folks it is 12:30am Saturday morning and Ivan is howling up a storm ... no pun intended! There are sounds outside that make gang wars and gun fights seem tolerable. The winds have definitely picked up here in Montego Bay and things like trees have learnt to walk freely. No vehicles on the road at this time, minimal rain it actually comes in waves of medium drizzles. The wind however, is constant, consistent and makes the Gilbert of 1988 seem as if it was a whirlwind by comparison ... the fact that this is all happening at night, without power does not make it any easier to bear.

In summary, I honestly can only write from what I hear outside, and from the sounds it doesn't sound like I will see much of anything in the morning. I can say that billboards that were in view of my house are gone with the wind. My car alarm has gone off numerous times just from the sheer force of the wind but I guess 140mph winds will do that to any vehicle!

The news has just indicated that Ivan has reduced its traverse speed to 17kmh and that it should become a CCAT5 hurricane before it actually makes landfall. I should note that with all the noise and wind and all I have mentioned here, the storm is still about 90 miles way from montego Bay ... so in a sense its only just begun!

For the persons who asked earlier about the hotels in Montego Bay, at this time I can just say that if they are by the sea, then they are going to be closed for a little while after Ivan is gone. The waves coming into Mobay were not small when the wind was lower, and now that it has really picked up I would imagine that the waves have also grown somewhat.

The scientist in me wants to say that Ivan is the perfect example of a well composed hurricane system ... a beautiful storm, on the other hand, my human side will ask what gate of hell it escaped from.

Ivan will then cross over Cuba during the predawn hours on Monday. Again, for much of this period between now and Monday, Ivan could be a Category Five hurricane. The disturbing thing is, the center of Ivan is projected to pass over or near the city of Havana!

That is disturbing indeed. From what I can see it seems like the track of the eye is a bullseye, first on Old Habana, and then straight over Havana. I only hope they have time and resources to take the needed precautions - though with 140-160 mph winds there is not much to do but get as far away as possible I guess.

And on 11. September, I hope the Floridans take Ivan as an omen not to mess up the electoral process once again. ;) Very good timing

There was a cartoon in the Washington Post along those lines, it showed Frances', Ivan's, and Charley's paths aiming at a section in Florida labeled convention center or something like that, with god sitting up on a cloud saying something like, "I wonder if they got the message?"


I'm glad I don't live in Florida, they're really gonna need help after Ivan...
 
Ivan is now Category 5 again, sustained winds of 165 mph. It is now projected to hit the Florida panhandle, not the main regions of Florida. Havana also looks like it will be spared the worst of the storm.

And apparently I just missed the two 1915 hurricanes on the list. Two Category 4 hurricanes made landfall in the US in one year once before, in 1915.

HURRICANE IVAN DISCUSSION NUMBER 38
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 PM EDT SAT SEP 11 2004

THERE HAVE BEEN SOME GRADUAL CHANGES IN THE STEERING PATTERN OVER
THE LAST DAY OR SO WHICH COULD RESULT IN THE HURRICANE MOVING ON A
TRACK NOT AS CLOSE TO SOUTH FLORIDA. WHILE THIS MAY BE GOOD NEWS
FOR SOUTH FLORIDA...IT IS NOT SO FOR OTHER REGIONS OF THE EASTERN
GULF COAST. WATER VAPOR IMAGES SHOW THAT A RIDGE OF HIGH PRESSURE
AT THE MID TO UPPER-LEVELS HAS DEVELOPED FROM THE GULF OF MEXICO
EASTWARD ACROSS FLORIDA. IT APPEARS THAT THIS RIDGE HAS BEEN
FORCING THE HURRICANE ON A MORE WESTWARD TRACK...DELAYING THE
EXPECTED NORTHWEST AND NORTHWARD TURN. ALTHOUGH THE NORTHWARD TURN
IS STILL FORECAST TO OCCUR AS A WEAKNESS DEVELOPS IN THE GULF OF
MEXICO...IT IS NOW EXPECTED TO OCCUR OVER EXTREME WESTERN CUBA AND
OVER THE OPEN WATERS OF THE GULF OF MEXICO. THIS TRACK INCREASES
THE HURRICANE RISK FOR THE NORTHEASTERN GULF OF MEXICO REGION AND
DECREASES IT FOR SOUTH FLORIDA. THE WESTWARD SHIFT OF THE OFFICIAL
FORECAST REMAINS IN AGREEMENT WITH GUIDANCE WHICH HAS ALSO BEEN
SHIFTING GRADUALLY WESTWARD.

AS WAS THOUGHT POSSIBLE...IVAN HAS REGAINED CATEGORY FIVE STRENGTH.
A RECONNAISSANCE PLANE JUST MEASURED 161 KNOTS AT 700 MB AND AN
EXTRAPOLATED PRESSURE OF 914 MB. THE DROP MEASURED 918 MB BUT IT
HAD 29 KNOTS AT THE SURFACE. INITIAL INTENSITY HAS BEEN INCREASED
TO 145 KNOTS. THERE ARE NO SKILLS IN PREDICTING CHANGES IN
INTENSITY WITH SUCH EXTREMELY INTENSE HURRICANES...SO IVAN IS KEPT
AT 145 KNOTS UNTIL LANDFALL IN CUBA. THEREAFTER...THE SHEAR IS
FORECAST TO INCREASE...SO A GRADUAL WEAKENING IS INDICATED.
NEVERTHERLESS... IVAN IS EXPECTED TO REACH THE UNITED STATES AS A
MAJOR HURRICANE.


FORECASTER AVILA

I'm sitting up here in Mobile with a strange bacterial infection. My girlfriend convinced me to go the doctor, and I told her, "Okay, I'll go, because I don't want to be sick when a major hurricane strikes." Chances are looking better that it's coming my way. :sad:

Havana also looks like it will be spared the worst of the storm.

Please keep in mind that the worst weather in a hurricane is almost always in the right-front quadrant with respect to motion. That would keep Havana in the danger zone, even if the eyewall did not pass over the city. Think of it like this. Ivan is traveling north at 10 miles per hour, with max sustained winds of 150 mph. To the west of the center, the winds are blowing against the direction of the storm, for a net wind of 140 mph. Quite often in a major hurricane, the sea will be pushed back, to reveal the sea floor, in such an area. But to the east of the center, winds are sustained at 160 mph (150 due to storm + 10 mph due to motion). This area is in the greatest threat of all, with storm surge and extreme winds the main dangers.

The eye of Ivan barely missed Jamaica, but since Jamaica was in Ivan's right-front quadrant, I am still expecting reports of mass devastation to come out of the island. Of course, they will need to get power restored.
 
Below is a list of intense hurricanes that have affected U.S. territory. Gilbert is included because of its effects on Texas. Please note that Ivan would rank 5th on this list...

At least 38 dead on the islands.. :undecide:

I had the sneaky feeling it was gonna go up the gulf. Are any members in it's predicted path? :confused:

UK sends aid to Grenada and Jamaica, but will anybody help Cuba? :confused:

Three Royal Navy ships. Two with technicians and medical staff to providing aid to Jamaica, and the other is in Grenada. The government has humanitarian experts on standby. Oxfam (British charity) is flying staff out and said providing drinking water would be the priority.

Is that total for Jamaica only, or the Caribbean as a whole?

I am in it's possible path. :sad: :cool: :shakehead: See the bottom of post #57 :gripe: :aargh: on page 3 :eek: :mad:

You can see I am having mixed emotions about all this. Plus, I am kinda sick right now. :vomit: I haven't eaten in 4 days...
 
Quasar1011 said:

AFAIK it's the current figure for the Caribbean as a whole (the figure reported on the Dutch news was 39, but that doesn't differ so much).

Most of them were on Grenada.
 
Quasar1011 said:

Total confirmed losses in the Caribbean, though I think some people are still unaccounted for.

I did know that :lol:

Should have said so. It's just that I kind of assumed that you would assume that I had remembered your post. Oops!

Quasar1011 said:
I hope that's coincidental, and not a reaction to big scarey storms coming your way.
 
Back down to 155 mph wind and pressure up to 918 mb / 27.11 in. Grand Cayman looks like it is about to get nailed.

If Ivan does what he is forecast to do... inland places like Dothan AL could get hurricane force winds... and Atlanta GA could get tropical storm force winds. Check out this chart:

Possibly a stupid question: Is rain from a hurricane saltier than 'regular' rain?
