How often does that happen? When was the last time?

Oho has such a exceptional track forecast, should pay a visit to British Columbia :eek: .


NHC has never done that before since that's never happened ever since the NHC took over the EPAc in 1988. In 1982 (EPHC era), this happened, however.

Don't know why the CPHC is adding for BF when there is no comma tail band.

HURRICANE OHO DISCUSSION NUMBER 16
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI CP072015
500 PM HST TUE OCT 06 2015

THERE HAVE BEEN SUGGESTIONS OF AN EYE OFF AND ON IN THE COLD
OVERCAST CLOUD AREA OVER THE CENTER OF OHO FOR A WHILE. THIS FEATURE
BECAME WELL-ENOUGH DEFINED AT 06/2330 UTC FOR BOTH HFO AND SAB TO
USE AN EYE PATTERN FOR THEIR DVORAK ANALYSES. JTWC DID NOT USE AN
EYE PATTERN BUT CAME UP WITH THE SAME CURRENT INTENSITY OF 4.5/77 KT
AS HFO AND SAB. I HAVE KEPT THE INITIAL INTENSITY AT 75 KT FOR THIS
ADVISORY BASED ON THESE SATELLITE ESTIMATES.

THE REASONING BEHIND THE TRACK FORECAST REMAINS UNCHANGED. A DEEP
NORTHEAST TO SOUTHWEST TROUGH REMAINS NORTHWEST OF THE HURRICANE.
THE SOUTHWESTERLY STEERING FLOW ASSOCIATED WITH THIS TROUGH IS
EXPECTED TO CARRY OHO TOWARD THE NORTHEAST WITH STEADILY INCREASING
FORWARD SPEED. THE CURRENT TRACK...WHICH HAS BEEN COORDINATED WITH
THE OCEAN PREDICTION CENTER...OPC...REMAINS CLOSE TO THE PREVIOUS
TRACK BUT IS A BIT FASTER.

UW-CIMSS SHOWED A BIG INCREASE IN VERTICAL WIND SHEAR...VWS...TO 28
KT FROM THE SOUTHWEST...WHILE SHIPS SHOWED 7 KT OF VWS FROM THE
SOUTHEAST. SO FAR...THE SATELLITE CLOUD PATTERN OVER OHO DOES NOT
SHOW MUCH SHEARING. OHO IS FORECAST TO BE OVER 25-27 DEGREES CELSIUS
WATER FOR THE NEXT 24 HOURS WITH THE SEA SURFACE TEMPERATURES
DROPPING RAPIDLY AFTER THAT. OHO IS FORECAST TO WEAKEN SLOWLY OVER
THE NEXT 24 HOURS...THEN MORE RAPIDLY THROUGH 48 HOURS. IN
COLLABORATION WITH OPC I HAVE FORECAST EXTRATROPICAL TRANSITION TO
OCCUR WITHIN 48 HOURS...WITH OHO DISSIPATING WITHIN 96 HOURS.

HURRICANE OHO DISCUSSION NUMBER 17
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI CP072015
1100 PM HST TUE OCT 06 2015

THE DISTINCT EYE OF OHO IS EMBEDDED IN A RING OF COLD OVERCAST
CLOUDS OVER THE CENTER OF THE HURRICANE. THIS FEATURE IS EVIDENT
DESPITE STRONG SOUTHERLY ENVIRONMENTAL VERTICAL WIND SHEAR IN THE
VICINITY...WHICH IS ESTIMATED TO BE 13 KT ACCORDING TO SHIPS
AND MORE THAN 30 KT BASED ON THE UW-CIMSS GUIDANCE. THE LATEST
SUBJECTIVE DVORAK SATELLITE INTENSITY ESTIMATES FROM PHFO AND JTWC
ARE 5.0/90 KT...WHILE SAB IS 5.5/102 KT. AT THE SAME TIME...THE
UW-CIMSS ESTIMATE IS 4.6/80 KT. SINCE THE OVERALL APPEARANCE OF OHO
HAS IMPROVED SINCE THE PREVIOUS ADVISORY...WE WILL INCREASE THE
INITIAL INTENSITY TO 90 KT.

THE INITIAL MOTION IS 025/25 KT...WHICH IS THE RESULT OF STEERING BY
A DEEP NORTH-NORTHEAST TO SOUTH-SOUTHWEST ORIENTED TROUGH LOCATED
WEST-NORTHWEST OF THE HURRICANE. THE STRONG SOUTHWESTERLY STEERING
FLOW ASSOCIATED WITH THIS DEEP TROUGH IS EXPECTED TO CONTINUE
TRANSPORTING OHO RAPIDLY TOWARD THE NORTH-NORTHEAST WITH STEADILY
INCREASING FORWARD SPEED. DESPITE THIS RAPID MOTION...THE FORECAST
MODELS ARE IN AMAZINGLY GOOD AGREEMENT ON THE TRACK DURING THE NEXT
COUPLE OF DAYS. THE LATEST FORECAST TRACK HAS BEEN ADJUSTED TO THE
WEST AND ACCELERATED COMPARED WITH THE PREVIOUS FORECAST. THESE
ADJUSTMENTS WERE NUDGED TOWARD THE ECMWF MODEL OUTPUT...AS WELL AS
THE LATEST TVCN AND GFEX CONSENSUS GUIDANCE.

OHO IS CURRENTLY OVER SEA SURFACE TEMPERATURES /SST/ OF AROUND 27C.
THE CURRENT FORECAST TRACK TAKES THE HURRICANE ACROSS DECREASING
VALUES OF SST AND REDUCED OCEAN HEAT CONTENT /OHC/ ACCORDING TO THE
MOST RECENT GUIDANCE FROM CIRA DURING THE NEXT 12 TO 18 HOURS. THE
SST AND OHC DECREASE DRAMATICALLY AFTER THAT. AT THE SAME TIME...
SHEAR IMPARTED BY THE DEEP TROUGH WILL LIKELY INCREASE IN THE
VICINITY OF THE SYSTEM. AS A RESULT...THERE MAY BE A SMALL WINDOW
OF OPPORTUNITY FOR OHO TO INTENSITY SLIGHTLY LATER TONIGHT. AFTER
THAT...OHO IS FORECAST TO REMAIN NEAR THE CURRENT INTENSITY...THEN
GRADUALLY WEAKEN DURING THE 12 TO 24 HOUR TIME PERIOD. MORE RAPID
WEAKENING IS ANTICIPATED BEYOND 24 HOURS...WITH OHO EXPECTED TO BE
A TROPICAL STORM WITHIN 36 HOURS. THE WEAKENING WILL LIKELY CONTINUE
AS EXTRATROPICAL TRANSITION IS COMPLETED BY DAY 2. THIS LATEST
INTENSITY FORECAST CLOSELY FOLLOWS THE IVCN CONSENSUS AND SHIPS.


FORECAST POSITIONS AND MAX WINDS

INIT 07/0900Z 20.4N 147.2W 90 KT 105 MPH

Definitely one weird storm. Not sure how many east-moving storms we've had EAST of Hawaii in the satellite era... and this one's a fairly intense hurricane, at least per advisories. It's never looked as intense as the advisory intensity but yeah to see a pretty well defined eye moving northeast to the northeast of the Hawaiian islands in a storm that BEGAN in the CPAC is actually really bizarre.

I would love to see it stay tropical into the EPAC simply because why not, let's go for some satellite era records while we're at it. Not gonna hurt anything besides maybe an hour or two of sleep for NHC forecasters if that happens. And I wonder how much will be left of the post-tropical low when it makes it to Canada... would be interesting to see a still-trackable surface low at that point but doubt that will actually happen.

Look at the latitude that it will maintain hurricane status at; if we were having a more zonal flow across the Pacific (which is entirely possible in October as opposed to mid summer), could it have aimed at California as a TS rather than BC/SE Alaska as an extra-tropical storm? SST in San Diego are still in the mid 70s.

:uarrow: Seems the CPHC forgot to remove some of their template text with the "*** [PLACE EXPECTED MOTION INFO HERE] ***". I don't think I've seen this mistake from the CPHC or NHC before. Anyone else?

It's being ripped apart this evening. LLC is around 25N/146.5E, MLC is way up north near 28.5N and accelerating away from the low-level center.

At the rate it's being affected by its obviously less favorable environment, and with its strong northward component of motion, one wonders whether it will even be tropical enough once it clips the EPAC to warrant the unprecedented advisories by the NHC. I honestly hope so just to see what they'd say, but I suspect they will declare it post-tropical really near the 140 line.

Yep, last several hours' worth of satellite images clearly indicates that this is very much the case. Clearly vertically disjunct storm, mid and upper levels rapidly racing ahead and forming the classic broad comma shape of an extratropical cyclone. In a race with Joaquin to see who becomes post-tropical first.

HURRICANE OHO DISCUSSION NUMBER 20
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI CP072015
500 PM HST WED OCT 07 2015

SATELLITE IMAGERY SHOWS THE COLD...HIGH TOPS THAT HAD COVERED THE
CENTER OF OHO HAVE BEEN SHEARED OFF TO THE NORTH-NORTHEAST
REVEALING THE LOW LEVEL CIRCULATION CENTER. THE LATEST SUBJECTIVE
DVORAK SATELLITE INTENSITY ESTIMATES WERE 4.0/65 KT FROM JTWC AND
4.5/77 KT FROM HFO. SAB JUDGED THE SYSTEM TO BE EXTRATROPICAL WITH
NO DVORAK ANALYSIS POSSIBLE. I HAVE SET THE INITIAL INTENSITY AT 75
KT.

STRONG VERTICAL WIND SHEAR...VWS...CONTINUES OVER OHO. UW-CIMSS
SHOWED AN EXTREMELY HIGH VWS OF 49 KT FROM THE SOUTH...WHILE SHIPS
DATA SHOWED 42 KT FROM THE SOUTH-SOUTHWEST. SST IS DOWN TO 24
DEGREES CELSIUS. MODEL GUIDANCE SHOWS GRADUAL WEAKENING OVER THE
NEXT 24 HOURS AS OHO STARTS TO BECOME EXTRATROPICAL.
HOWEVER...ENERGY FROM A DIGGING JET STREAM IS FORECAST TO CAUSE
THE LOW TO STRENGTHEN AGAIN AFTER BECOMING EXTRATROPICAL. IN
COLLABORATION WITH THE OCEAN PREDICTION CENTER...OPC...WE HAVE
FORECAST OHO TO BE POST-TROPICAL/EXTRATROPICAL IN 24 HOURS. AS OHO
BECOMES EXTRATROPICAL...ITS WIND FIELD WILL EXPAND AND BECOME
ASYMMETRIC...EXTENDING MUCH FARTHER OUT ON THE EAST SIDE OF THE
SYSTEM.

THERE HAS BEEN LITTLE CHANGE IN THE TRACK FORECAST. OHO IS EXPECTED
TO CONTINUE RACING TOWARD THE NORTH-NORTHEAST GUIDED BY STEERING
FLOW ASSOCIATED WITH A DEEP TROUGH NORTHWEST OF THE HURRICANE. THE
FORECAST TRACK SHOWS OHO CROSSING EAST OF 140W INTO THE AREA OF
RESPONSIBILITY OF THE NATIONAL HURRICANE CENTER...NHC...IN MIAMI
FLORIDA AROUND 18 HOURS FROM NOW. IT IS POSSIBLE THAT NHC MAY TAKE
OVER RESPONSIBILITY FOR FORECASTS ON OHO BEFORE IT BECOMES
EXTRATROPICAL. WHEN THE SYSTEM DOES BECOME EXTRATROPICAL IT WILL
BECOME THE RESPONSIBILITY OF OPC AND WILL BE COVERED BY THE OPC HIGH
SEAS FORECASTS.

No way in the world this is a hurricane. It's fully ET and there aren't likely any hurricane force winds. LLC may be completely gone now.

I'm not sure why the CPHC was so bullish on Oho throughout its life as they seem to be rather conservative usually, but this looks even less tropical than Joaquin, which is of course post-tropical at this point.

It was hard to even find a surface circulation in microwave and visible images yesterday and I suspect it has spun down rather quickly. Not sure why they've suggested it has held on as a full fledged hurricane. Ah well.

POST-TROPICAL CYCLONE OHO DISCUSSION NUMBER 22
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI CP072015
500 AM HST THU OCT 08 2015

OHO IS NO LONGER A TROPICAL SYSTEM. SATELLITE PRESENTATION
CONTINUES TO DEGRADE...WITH ANY REMAINING DEEP CONVECTION PUSHED FAR
TO THE NORTH NORTHEAST WITHIN UNRELENTING 45 TO 55 KT OF SHEAR.
SHIPS ANALYSIS DEPICTS THIS SYSTEM PASSING OVER 22C WATER. THIN
LAYERED CLOUDS PARTIALLY OBSCURE THE LOW LEVEL CIRCULATION
CENTER...LLCC...BUT ANIMATION KEEPS FIX CONFIDENCE QUITE HIGH. WITH
NO DEEP CONVECTION ANYWHERE NEAR THE LLCC...RELIABLE SATELLITE
INTENSITY ESTIMATES ARE BASED ON MET DECREASING ACCORDING TO THE
CONCEPTUAL MODEL. THEREFORE...IT SEEMS REASONABLE TO ASSIGN AN
INITIAL INTENSITY OF 60 KT FOR THIS FINAL ADVISORY BASED ON THE
WEAKENING TREND.

INITIAL MOTION IS 020/37 KT...WITH THE DEEP TROUGH NORTHWEST OF
THIS SYSTEM PROVIDING THE ONLY MAIN INFLUENCE. WE COLLABORATED WITH
THE OCEAN PREDICTION CENTER...OPC...FOR ALL POINTS ALONG THE
FORECAST TRACK. OPC CONTRIBUTED WIND AND SEAS RADII AS WELL. THE
CURRENT FORECAST TRACK KEEPS OHO HEADED TOWARD BRITISH COLUMBIA AND
THE ALASKAN PANHANDLE THROUGH 24 HOURS...THEN CURVES THE TRACK
NORTHWESTWARD AT 36 AND 48 HOURS AS THIS SYSTEM MOVES ALONG THE
NORTHEASTERN FLANK OF A LARGE POLAR LOW FORMING ACROSS THE
ALEUTIANS. AS AN EXTRATROPICAL STORM LOW...ITS WIND FIELD WILL
EXPAND AND BECOME HIGHLY ASYMMETRIC.

THE INTENSITY FORECAST HAS CHANGED VERY LITTLE FROM LAST TIME.
EXTRATROPICAL OHO WILL WEAKEN THROUGH 24 HOURS...SPINNING DOWN AT
THE MET RATE. HOWEVER...BAROCLINIC FORCES WILL STRENGTHEN THE
REMNANTS OF OHO BACK TO NEAR-HURRICANE STRENGTH...BUT STILL AS AN
EXTRATROPICAL STORM LOW...BETWEEN 24 AND 36 HOURS. THIS STORM LOW
WILL THEN WEAKEN AGAIN BY 48 HOURS AS IT INTERACTS WITH THE ALASKAN
PANHANDLE...THEN DISSIPATE INLAND BY 72 HOURS.

THIS IS THE LAST DISCUSSION ISSUED BY THE CENTRAL PACIFIC HURRICANE
CENTER ON THIS SYSTEM. FUTURE INFORMATION ON THIS SYSTEM CAN BE
FOUND IN HIGH SEAS FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE
OCEAN PREDICTION CENTER...OPC...UNDER AWIPS HEADER HSFEP1 AND WMO
HEADER FZPN01 KWBC.
