This is the strongest looking cat3 storm I have ever seen. Its hard for me to believe the winds are still 125 mph.

Sounds like good news that it did not intensify more. And you're probably right about Dennis exiting the column of warmer water. That may level out the intensification to landfall.

Well, our nephew's new house is almost finished in Mobile but he couldn't get insurance to close in the last ten days because of the storms. He might not have any thing to close on come Monday. Oh I asked him if the builder at least put the code required storm panels up. He said that their code doesn't require them!!! I was SHOCKED in dis belief!!! :eek:

TCDAT4
HURRICANE DENNIS DISCUSSION NUMBER 23
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
10 PM CDT SAT JUL 09 2005

AFTER DEEPENING AT A RATE THAT BORDERED ON INSANE DURING THE
AFTERNOON...DENNIS HAS CONTINUED TO STRENGTHEN AT A MORE NORMAL
RATE THIS EVENING. REPORTS FROM AN AIR FORCE RESERVE HURRICANE
HUNTER AIRCRAFT SHOW THAT THE CENTRAL PRESSURE HAS FALLEN TO 941
MB...WITH MAXIMUM FLIGHT-LEVEL WINDS OF 122 KT IN THE NORTHEAST
QUADRANT. BASED ON THIS...THE INITIAL INTENSITY IS 110 KT. IT IS
EXPECTED THAT WHEN THE AIRCRAFT AGAIN SAMPLES THE NORTHEAST EYEWALL
THAT IT WILL FIND STRONGER WINDS THAT WILL JUSTIFY UPGRADING DENNIS
TO A CATEGORY FOUR HURRICANE. IT SHOULD BE NOTED THAT ALTHOUGH
DENNIS HAS A VERY LARGE OUTER WIND FIELD... THE HURRICANE FORCE
WINDS ARE CONFINED TO A VERY SMALL AREA NEAR THE CENTER.

THERE IS NO CHANGE TO THE TRACK FORECAST PHILOSOPHY. DENNIS IN ON
THE SOUTHWEST SIDE OF A MID/UPPER LEVEL RIDGE EXTENDING FROM THE
WESTERN ATLANTIC NORTHWESTWARD INTO THE OHIO VALLEY...AND EAST OF A
MID/UPPER-LEVEL TROUGH EXTENDING FROM ARKANSAS SOUTH-SOUTHWESTWARD
TO JUST OFF THE TEXAS COAST. THIS COMBINATION SHOULD KEEP DENNIS
ON A GENERAL NORTHWESTWARD TO NORTH-NORTHWESTWARD TRACK FOR AT
LEAST 2 DAYS...WITH THIS MOTION BRINGING THE STORM INLAND ON
SUNDAY. TRACK MODEL GUIDANCE IS TIGHTLY CLUSTERED IN CALLING FOR
LANDFALL IN THE PENSACOLA FLORIDA-PASCAGOULA MISSISSIPPI AREA...AND
THE OFFICIAL FORECAST TRACK IS BASICALLY DOWN THE MIDDLE OF THE
CLUSTER JUST A LITTLE TO THE LEFT OF THE PREVIOUS FORECAST. AFTER
LANDFALL...DENNIS SHOULD SLOW AND GRADUALLY RECURVE INTO THE
WESTERLIES OVER THE MID-MISSISSIPPI AND OHIO VALLEYS.

THE COMBINATION OF TIGHT INNER CORE...GOOD TO EXCELLENT OUTFLOW OVER
THE NORTHEASTERN SEMICIRCLE...WARM SEA SURFACE TEMPERATURES...AND
COLD CONVECTIVE TOPS SUGGESTS THAT DENNIS HAS NOT YET FINISHED
STRENGTHENING. THE INTENSITY FORECAST CALLS FOR THE SYSTEM TO
REACH 120 KT IN 12 HR. AFTER THAT...CONCENTRIC EYEWALL CYCLES
ALONG WITH POSSIBLE DRY AIR INTRUSION AND POSSIBLY INCREASING SHEAR
WILL LIKELY END STRENGTHENING. DENNIS WILL WEAKEN AFTER LANDFALL
AND EVENTUALLY BECOME A LOW PRESSURE AREA.

34 KT WINDS IN THE SOUTHEASTERN QUADRANT HAVE BEEN REVISED OUTWARD
BASED ON OBSERVATIONS AT KEY WEST.

FORECASTER BEVEN


FORECAST POSITIONS AND MAX WINDS

INITIAL 10/0300Z 26.6N 85.3W 110 KT
12HR VT 10/1200Z 28.2N 86.6W 120 KT
24HR VT 11/0000Z 30.6N 87.9W 120 KT...INLAND
36HR VT 11/1200Z 32.9N 89.0W 65 KT...INLAND
48HR VT 12/0000Z 34.8N 89.8W 30 KT...INLAND
72HR VT 13/0000Z 37.5N 89.0W 25 KT...INLAND DISSIPATING
96HR VT 14/0000Z 38.0N 86.5W 20 KT...INLAND REMNANT LOW
120HR VT 15/0000Z 38.5N 82.5W 20 KT...INLAND REMNANT LOW

This is no 125 mph cat3....This looks like a strong cat4 hurricane of between 140 to 145 mph winds....Unless the wind field is still messed up.

There has not been a plane since 8 PM.For sure when the plane goes in it will find stronger winds.

He may be about to undergo an ERC, which is probably not a good thing. He's about to head over that warmer water, and he has plenty of time to build up an even stronger head of steam. It would be better if an ERC didn't take place until close to landfall--he might have become a little disorganized and lost some steam right before he hit land.


This is not the last ERC the storm will go under until landfall. I would count on 2 more.


ERCs don't happen that often. This storm has less than one day left over water. There will probably be no more ERCs.


AH, I was always under the assumption that they occured approx. every 12 hours?


As I understand it, the eye continues to shrink as the storm gains intensity--until the inner eye can no longer support the storm. The inner eye collapses and the outer, larger eye becomes the new center of circulation. I have heard that, generally speaking, the more powerful a storm is, the more ERCs you can expect. I don't know if that is exactly true or not, but it makes sense. Ivan certainly went through a considerable amount of ERCs. But, as has been mentioned, we're less than 24 hours until landfall, and ERCs take time. So if he is about to start an ERC, he likely does not have enough time to go through another one prior to landfall. If he did, God help us all--because in order for him to go through another ERC that quickly, he would probably be approaching Cat 5 intensity.

This storm looks like Ivan southeast of Jamaica as it became a cat5 for the first time. I'm waiting for the recon an I'm having a hard time waiting.
