Hurricane Ivan: Now A CAT 4/Models Shift Again
NHC | 9-07-2004 | my favorite headache

Posted on 09/07/2004 5:45:54 PM PDT by My Favorite Headache

Hurricane Ivan has become a Category 4 Hurricane again! Winds over 130 mph and gusts up to 160 currently. The models have shifted the last 36 hrs like never before. My fellow Floridians might not like the 8 pm model that has just come out:

Actually my back started to spasm and quit. Back and legs braced against the corner of the pier were the sorest. Each big fish that came over the deck was shooting milt. They were going a little crazy because it was like a 20 year tide. The whole of Treasure Island was submerged. But they were gentle swells. Little wind. Absolutely the perfect confluence of weather conditions for an epic bull red run in the pass. Have yet to see it replicated. the reason they were there in force is the flooding of the salt marsh. The eggs attached to freshly submerged salt grass. If we get a big hurricane south of us, it could happen again. Unfortunately the pass pier is down right now. A storm last year put it under. It survived a lot before that happened. Guess it was a weird storm coming in at a bad angle. Hell I was on the pier during Chantal and Jerry and on one of those I had to tell the pier guy to shut it down. 2 by 6's were bouncing up and down like typewriter keys in the middle of the pier. Not safe. I used to always make it a point ot be at the beach when the easier storms came ashore. Something about that weather that makes you feel "alive". Or maybe it was the Budweiser. Not sure.

Allen was the monster, as big as the gulf and it scared people nearly to death. It ended up being a non event for everywhere except a lonely stretch of King Ranch.

King Ranch and my parents house. Large, large pine trees, high winds and roofs don't mix well

Hurricane Ivan Discussion Number 25


Statement as of 11:00 am EDT on September 08, 2004


Last fix from a reconnaissance plane earlier this morning indicated
that the pressure increased to 955 mb but flight-level winds were
still 133 knots in the northern eyewall. Since then...high
resolution visible satellite images reveal that the eye is not as
distinct as earlier but still visible. Initial intensity remains at
120 knots. Because the hurricane will have to fight some shear and
will be moving just north of the south American coast...there may
be some weakening during the next 12 to 24 hours. Thereafter...the
hurricane will be over the northwestern Caribbean Sea where there
is high oceanic heat content and lower shear. So...Ivan is expected
to intensify before reaching Cuba. Neverthereless...these are
basically fluctuations in intensity and the bottom line is that
Ivan is expected to remain a very dangerous hurricane.
Satellite and earlier reconnaissance fixes indicate that Ivan is
moving toward the west-northwest or 285 degrees at 14 knots. During
the next 24 to 48 hours...the subtropical ridge to the north of
Ivan is expected to change little...forcing Ivan to move toward the
west-northwest. Thereafter...the ridge is forecast to weaken and a
broad mid-level trough will likely become established over the Gulf
of Mexico. This pattern should move the hurricane on a northwest
and north-northwest track with a decrease in forward speed. It must
be emphasized that the forecast track beyond 72 hours is highly
uncertain since steering currents will be weak and are currently
not well-defined in the forecast models. In fact...some reliable
models bring Ivan over Florida and another reliable group move the
hurricane toward the Gulf of Mexico. There is no apparent reason to
favor one scenario over the other at this time. Therefore...the
official forecast remains near the global model consensus and
presumes that there will be enough ridging to keep the hurricane on
a northwest to north-northwest track... bringing dangerous Ivan
over western Cuba in 4 days and into the eastern Gulf of Mexico by
day five.

History Of Category 5 Hurricanes

Category 5 hurricanes were a lot more frequent in the past. It is a mystery why the frequency of these cat 5's dropped off beginning 1,100 years ago.

Thanks for the reply, interesting story. One year we went, a weaker hurricane had previosuly dredged the 1st cut well over our heads, and made the the 1st bar so high the fish couldnt swim over it. Made fishing real hard from the bank. We probably should have fished a pier that time. I hope not to fish chocklate milk and riptides, and that the seaweed doesnt come in.

Most of all I hope it doesnt hit the US.

That Labor Day hurricane of 35 was one of the worst.
I was in the eyewall of Andrew, in 92, but thought it was a cat 4. I guess there's still some controversy over that, since it blew away all the wind instruments rather quickly. Anyway, if there're less cat 5's, I can only say that it's a great thing.

This morning's models, bad as they look for FL, are a slight improvement over yesterday afternoon's, at least in terms of the outlook for So FL.
Only slight, though.

I'm curious how anyone could know the frequency of Cat 5's 1,100 years ago as opposed to today...

No sense worrying too much--it probably is lack of communication ability.

The Red Cross and Salvation Army use amateur radio to transmit "Disaster Welfare Inquiries" into the stricken area, and back out again.

Time to short nutmeg futures. In all seriousness, they aren't used to getting hurricanes that far south in the Caribbean, let alone Cat 3 storms.

There are a bunch of different phonetic alphabets running around out there. ICAO (the one most of us know; Alfa-Bravo-Charlie), the police's (David-King-George), the old WWII (Abel-Baker-Charlie-Dog)...

"I'm curious how anyone could know the frequency of Cat 5's 1,100 years ago as opposed to today..."

The study I read about dealt with sand grain size in the sediment of coastal lakes. Apparently only a cat 5 can carry certain grain sizes of sand far enough to fall into these coastal lakes. I only remember Lake Shelby as one of the lakes used in the study.

the NOGAPS was the model that held the most consistency during the 72 hours prior to landfall on the east coast of FL.
FYI -- The European forecast model over it's past 6 runs (3 days) has had the storm kiss the FL keys and then run up, off the coast, toward NC. The other models are now coming in line with it's predictions
