You just never know. But on a more realistic note, he is entering much cooler waters tomorrow and that dry air will sink along with it.

Very dry and stable air and cooler sst,s are on the doorstep. It has been remarkable that at this point is this strong,but from now is all downhill.

HURRICANE DANIEL DISCUSSION NUMBER 16
NWS NATIONAL HURRICANE CENTER MIAMI FL EP042012
800 PM PDT SAT JUL 07 2012

DANIEL HAS CONTINUED TO STRENGTHEN...WITH A WELL-DEFINED EYE FORMING
AROUND THE TIME OF THE LAST ADVISORY. DVORAK CURRENT INTENSITY
ESTIMATES WERE 77 KT AND 90 KT AT 00 UTC FROM TAFB AND SAB...
RESPECTIVELY...AND THE LATEST ADT ESTIMATE FROM UW-CIMSS IS ABOUT
105 KT. GIVEN THE WIDE RANGE OF ESTIMATES...THE INTENSITY IS
CONSERVATIVELY RAISED TO 90 KT.

DANIEL WILL BE CROSSING THE 26C ISOTHERM WITHIN THE NEXT 6 TO 12
HOURS...SO THE HURRICANE IS LIKELY NEAR ITS PEAK INTENSITY AND
SHOULD BEGIN TO WEAKEN ON SUNDAY. THE NHC FORECAST ASSUMES A
GRADUAL DECAY IN WINDS...FOLLOWING THE SHIPS MODEL DURING THE FIRST
2 DAYS AND THE LGEM GUIDANCE ON DAYS 3 THROUGH 5. THE NEW INTENSITY
FORECAST IS SLIGHTLY HIGHER THAN THE PREVIOUS ONE SINCE DANIEL HAS
STRENGTHENED A LITTLE MORE THAN EXPECTED.

THE INITIAL MOTION IS 275/10 KT. DANIEL SHOULD CONTINUE TO MOVE
WESTWARD OVER THE NEXT 5 DAYS AS A MID-LEVEL RIDGE TO ITS NORTH
BUILDS WESTWARD. WITH THE EXCEPTION OF THE UKMET...THE TRACK
GUIDANCE HAS SHIFTED TO THE NORTH ON THIS CYCLE...LEAVING THE
PREVIOUS FORECAST ON THE SOUTHERN EDGE OF THE ENVELOPE. ALSO...IN
DIRECT CONTRAST TO PREVIOUS DAYS...THE ECMWF MODEL IS NOW ON THE
NORTHERN SIDE OF THE GUIDANCE. GIVEN THE OVERALL SHIFT IN THE
MODELS...THE NHC FORECAST IS ADJUSTED A BIT NORTH OF THE PREVIOUS
ONE THROUGH DAY 4.


FORECAST POSITIONS AND MAX WINDS

INIT 08/0300Z 14.9N 121.2W 90 KT 105 MPH
12H 08/1200Z 15.3N 123.0W 90 KT 105 MPH

Yea, well, the next question should be is this system a threat to Hawaii? I'm gonna say no, not as a TC at least.

They have it going SW as a weakning system. If it can somehow maintain strength (lol) then it may get pulled north.

TropicalAnalystWx13,

Daniel doesn't look to be weakening at all. Past hour ADT #'s going back up.

Looks to be a low major hurricane.

Well, I said Daniel peaked twice already, and both times I was incorrect, so you are not the only one who called the peak too early.

Based on all avalable data and satellite presentation, i would place the peak of hurricane daniel at 100 knots tied with hurricane bud for strongest this east pacific season...

Sounds fair, but intensity is measured by pressure not winds (most of the time).

Looks like Daniel may make it to the next advisory as a major hurricane.

UW-CIMSS has 110kts. :double:

Daniel remembers its 2006's self and is trying its best to copy. Everytime I think the NHC is about to lower its strength, they either leave it alone or increase it and that has happened 4 times now! It's possible it is or was a major hurricane which is unbelievable but assuming 90 knots...that's close and just think, the NHC at one point was calling for this NOT to become a hurricane! Same with Bud.

I notice Daniel is trying to get smaller as it enters this new environment. The convection around the eye has been extremely active and causing the eye to fluctuate often. It won't make it to Hawaii obviously but a basin crosser is becoming likely and the timeframe in which the NHC puts remnant low at keeps shifting at 120 hours for days now.

As Daniel entered the environment with lower SST, weak vertical wind shear, and is now losing its rainband, it may become an annular hurricane.

Annular hurricanes generally have large eyes... Will see if that happens. It seems unphased with all that dry air around it.

...DANIEL STILL STRENGTHENING...NOW A MAJOR HURRICANE...

HURRICANE DANIEL DISCUSSION NUMBER 17
NWS NATIONAL HURRICANE CENTER MIAMI FL EP042012
200 AM PDT SUN JUL 08 2012

DANIEL HAS STRENGTHENED SOME MORE SINCE THE LAST ADVISORY.
GEOSTATIONARY SATELLITE IMAGES INDICATE THAT THE CLOUD TOPS
SURROUNDING THE EYE HAVE COOLED TO NEAR -75C AND THE EYE HAS BECOME
MORE DISTINCT OVER THE PAST COUPLE OF HOURS. BASED ON THE LATEST
SATELLITE INTENSITY ESTIMATES...THE INITIAL WIND SPEED IS INCREASED
TO 100 KT...MAKING DANIEL A MAJOR HURRICANE. IT IS SOMEWHAT
SUPRISING THAT DANIEL IS STILL GAINING STRENGTH AS THE EYE HAS
CROSSED THE 26C ISOTHERM. I CAN ONLY ASSUME THAT THE HURRICANE HAS
REACHED ITS PEAK INTENSITY AS THESE LOW WATER TEMPERATURES
TYPICALLY CAUSE THUNDERSTORM ACTIVITY TO LESSEN...RESULTING IN A
DECREASE IN THE WIND SPEED. THE OFFICIAL FORECAST FOLLOWS THE TREND
OF THE LGEM AND SHIPS MODELS AND SHOWS DANIEL STEADILY WEAKENING
THROUGHOUT THE FORECAST PERIOD AS IT MOVES OVER EVEN COOLER WATER
AND INTO A MORE STABLE ENVIRONMENT.

THE HURRICANE IS MOVING WESTWARD AT ABOUT 10 KT. THIS GENERAL
MOTION WITH AN INCREASE IN FORWARD SPEED IS FORECAST FOR THE NEXT 5
DAYS AS A SUBTROPICAL RIDGE REMAINS IN PLACE TO THE NORTH OF THE
CYCLONE. THE OFFICIAL TRACK FORECAST IS A TAD SLOWER THAN THE
PREVIOUS ONE AND IS CLOSE TO THE MULTI-MODEL CONSENSUS.

THE 34-KT AND 50-KT WIND RADII WERE MODIFIED BASED ON AN ASCAT PASS
AT 0554 UTC. THIS SCATTEROMETER PASS CONFIRMED THE COMPACT WIND
FIELD OF DANIEL.
