I'll say they'll change the motion to NNW.

BULLETIN
HURRICANE DENNIS INTERMEDIATE ADVISORY NUMBER 22A
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
8 PM CDT SAT JUL 09 2005

...DANGEROUS CATEGORY 3 DENNIS CONTINUING TO STRENGTHEN RAPIDLY...

A HURRICANE WARNING REMAINS IN EFFECT FOR PORTIONS OF THE
NORTHEASTERN GULF COAST FROM THE STEINHATCHEE RIVER FLORIDA WESTWARD
TO THE MOUTH OF THE PEARL RIVER AT THE LOUISIANA-MISSISSIPPI
BORDER.

A TROPICAL STORM WARNING REMAINS IN EFFECT ALONG THE FLORIDA WEST
COAST FROM EAST OF THE STEINHATCHEE RIVER SOUTHWARD TO FLAMINGO...
AND FOR THE LOWER FLORIDA KEYS WEST OF SEVEN MILE BRIDGE. A
TROPICAL STORM WARNING IS ALSO IN EFFECT FOR THE SOUTHEASTERN
LOUISIANA COAST WEST OF THE MOUTH OF THE PEARL RIVER TO GRAND
ISLE...INCLUDING METROPOLITAN NEW ORLEANS AND LAKE PONCHARTRAIN.

A HURRICANE OR TROPICAL STORM WARNING MEANS THAT HURRICANE OR
TROPICAL STORM CONDITIONS...RESPECTIVELY...ARE EXPECTED WITHIN THE
WARNING AREA WITHIN THE NEXT 24 HOURS. PREPARATIONS TO PROTECT LIFE
AND PROPERTY SHOULD BE RUSHED TO COMPLETION IN THE HURRICANE
WARNING AREA.

FOR STORM INFORMATION SPECIFIC TO YOUR AREA...INCLUDING POSSIBLE
INLAND WATCHES AND WARNINGS...PLEASE MONITOR PRODUCTS ISSUED
BY YOUR LOCAL WEATHER OFFICE.

AT 8 PM CDT...0100Z...THE CENTER OF HURRICANE DENNIS WAS LOCATED
NEAR LATITUDE 26.3 NORTH...LONGITUDE 85.1 WEST OR ABOUT 275 MILES
SOUTH OF PANAMA CITY FLORIDA AND ABOUT 365 MILES SOUTHEAST OF
BILOXI MISSISSIPPI.

DENNIS IS MOVING TOWARD THE NORTHWEST NEAR 13 MPH AND A GRADUAL TURN
TOWARD THE NORTH-NORTHWEST IS EXPECTED TONIGHT OR SUNDAY. THIS
MOTION WILL BRING THE CENTER OF DENNIS NEAR THE NORTHERN GULF
COAST ON SUNDAY.

REPORTS FROM AN AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT INDICATE
THAT MAXIMUM SUSTAINED WINDS ARE NOW NEAR 125 MPH...WITH HIGHER
GUSTS. THIS MAKES DENNIS A CATEGORY 3 HURRICANE ON THE
SAFFIR-SIMPSON SCALE. ADDITIONAL STRENGTHENING IS EXPECTED...AND
DENNIS COULD BECOME A CATEGORY 4 HURRICANE BEFORE LANDFALL ON THE
NORTHERN GULF COAST.

HURRICANE FORCE WINDS EXTEND OUTWARD UP TO 40 MILES...FROM THE
CENTER...AND TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP
TO 175 MILES.

THE LATEST MINIMUM CENTRAL PRESSURE REPORTED BY THE HURRICANE HUNTER
IS 942 MB...27.82 INCHES.

DENNIS IS EXPECTED TO PRODUCE TOTAL RAINFALL ACCUMULATIONS OF 4 TO
8 INCHES ACROSS THE FLORIDA KEYS...THE FLORIDA WEST COAST...THE
FLORIDA PANHANDLE...SOUTHERN ALABAMA...AND SOUTHERN MISSISSIPPI.
ISOLATED TOTALS NEAR 12 INCHES ARE POSSIBLE NEAR WHERE DENNIS MAKES
LANDFALL ALONG THE GULF COAST. ADDITIONAL RAIN ACCUMULATIONS OF 3
TO 6 INCHES ARE POSSIBLE ACROSS CENTRAL CUBA...WHICH COULD PRODUCE
LIFE-THREATENING FLASH FLOODS AND MUDSLIDES.

STORM SURGE WILL GRADUALLY DECREASE ALONG THE LOWER FLORIDA KEYS
TONIGHT. A STORM SURGE OF 2 TO 4 FEET IS POSSIBLE ALONG THE
SOUTHWESTERN COAST OF FLORIDA TONIGHT AND SUNDAY MORNING. A STORM
SURGE OF 12 TO 14 FEET...ACCOMPANIED BY LARGE AND DANGEROUS
BATTERING WAVES...IS POSSIBLE NEAR AND TO THE EAST OF WHERE
THE CENTER OF DENNIS CROSSES THE NORTHERN GULF COAST ON SUNDAY.

ISOLATED TORNADOES WILL BE POSSIBLE OVER THE CENTRAL AND SOUTHERN
FLORIDA PENINSULA AND THE FLORIDA KEYS THIS EVENING...AND ACROSS THE
FLORIDA PANHANDLE TONIGHT AND SUNDAY.

REPEATING THE 8 PM CDT POSITION...26.3 N... 85.1 W. MOVEMENT
TOWARD...NORTHWEST NEAR 13 MPH. MAXIMUM SUSTAINED
WINDS...125 MPH. MINIMUM CENTRAL PRESSURE... 942 MB.

THE NEXT ADVISORY WILL BE ISSUED BY THE NATIONAL
HURRICANE CENTER AT 10 PM CDT.

I'm predicting Dennis will make landfall the same strength he was before landing on Cuba

So apparently over the last hour its tracked .2N and .1 West...What angle would that be at? Not very good at calculating angles.

[wxwatcher91]

This is like Andrew only I'd say it will be even stronger pretty soon

look at the satellite!!!! ITS ALMOST PERFECTLY SYMMETRICAL!
Dennis has gotten a LOT smaller =higher winds

[gkrangers]

Sorry, but its not Andrew.

[Lowpressure]

Doubtful it gets over 160 at landfall as per your Andrew statement, and smaller does NOT equal stronger. Be careful with your comments, too many people are watching, be reasonable.

i'd guess nnw

[Stratosphere747]

What is scary, is the fact that is so much more impressive looking than Ivan was at this point nearing the coast..

We can only hope that it begins to lose some strength.

[Mac]

From the lastest IR sat images, it appears to me as though his eye in contracting and a double eyewall may have formed. 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.

Oh I know that it is way not Andrew and I'm comparing the strength wise not with when it actually hit land... I know its not a Andrew... I just compared the contracting with him

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.

[Brent]

Conference call just ended...

125 mph intensity

140 mph near Mobile Bay at 7pm tomorrow

Recon hasn't sampled NE quadrant yet, will likely find stronger winds, intensification has slowed from earlier "insane" rate(NHC quote).

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

[sprink52]

This is very serious. I hope no one has stayed behind to watch this "snake" bite!! Move away and let it come. Come back Monday and start clean up and recovery. Thankfully help is on the way. We are a strong people and we will recover.

[mtm4319]

30.6, 87.9 is near Daphne... looks like the forecast was moved slightly west.
