JTWC has a habit of going 135kt when a storm gets a T7.0 for the first time. We will see what they say. IMO its 140kt.

Since 00Z, the JTWC Best Track has not been updated, same goes with the ACE which solely relies on that BT.

Gang, can we quit with embedding mega file sized animations? Links will do fine for those who want to view them.

Another low end 140 knots category 5...When will recon return?

I know Wilma is the strongest in the Atlantic but why even mention her? There have been countless of other similiar typhoons that intensified at this rate plus highest Wilma got up to based on dvorak is only 6.5...Recon?

Wow so it did become a cat 5 after all. What a turnaround.

Wilma is being bought up because it intensified VERY quickly in 24 hours.

I compared it to Wilma solely on the rate of intensification. 48 hours from depression to cat 5.

Well record for 24 hours is Super Typhoon Forrest which dropped 100 mb from 976 to 876 mb...Record at that time...

But anyways back to Genevieve...

Looking very impressive...

Wilma's Dvorak was later adjusted to 7.8 and then it is one of the few modern-day (2000 up) cyclones to have that.

Amazing storm. Going from a weak tropical storm to a Cat 5 in only 48 hours...

Could Genevieve recurve back across 180 before becoming extratropical? In that case, CPHC takes back control?

As for the central pressure, if the storm is 140 kt, I would guess it to be around 935mb (higher than Dvorak due to the ridge nearby). At the previous advisory supporting 130 kt, I would guess 944mb at that time.

Becoming Annular?

WDPN32 PGTW 071500
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR SUPER TYPHOON 11W (GENEVIEVE) WARNING
NR 42//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
SUPER TYPHOON (STY) 07E (GENEVIEVE), LOCATED APPROXIMATELY 692 NM
WEST OF JOHNSTON ISLAND, HAS TRACKED WEST-NORTHWESTWARD AT 14 KNOTS
OVER THE PAST SIX HOURS. STY 07E HAS RAPIDLY INTENSIFIED OVER THE
PAST 24 HOURS INCREASING 75 KNOTS FROM 65 KNOTS TO 140 KNOTS.
ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY DEPICTS A COMPACT
SYSTEM WITH A 15 NM EYE, THEREFORE, THERE IS GOOD CONFIDENCE IN THE
CURRENT POSITION. EIR DEPICTS AN ANNULAR SIGNATURE WITH A SYMMETRIC
RING OF UNIFORM CONVECTION.
A 071231Z TRMM IMAGE INDICATED A 60 NM
DIAMETER EYEWALL WITH A CONVECTIVE BAND OVER THE SOUTH QUADRANT.
ANIMATED WATER VAPOR IMAGERY REVEALS RADIAL OUTFLOW WITH EXCELLENT
POLEWARD OUTFLOW INTO THE STRONG TUTT POSITIONED TO THE NORTH AND
NORTHEAST. THE CURRENT INTENSITY IS ASSESSED AT 140 KNOTS BASED ON
DVORAK INTENSITY ESTIMATES OF 140 KNOTS FROM PGTW AND KNES. STY 07E
IS CURRENTLY TRACKING ALONG THE SOUTHWEST PERIPHERY OF A DEEP
STEERING RIDGE POSITIONED TO THE NORTHEAST.
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. STY 07E IS FORECAST TO TRACK WEST-NORTHWESTWARD THROUGH TAU 12
BUT IS EXPECTED TO TURN POLEWARD AS THE RIDGE BUILDS TO THE EAST AND
BECOMES POLEWARD ORIENTED. THE SYSTEM IS FORECAST TO INTENSIFY TO A
PEAK OF 145 KNOTS BY TAU 12 BUT SHOULD MAINTAIN SUPER TYPHOON
STRENGTH THROUGH TAU 36 DUE TO FAVORABLE ENVIRONMENTAL CONDITIONS.
AVAILABLE DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT AND SUPPORTS
THE JTWC FORECAST TRACK.
C. IN THE EXTENDED TAUS, THERE IS INCREASED UNCERTAINTY DUE TO
THE PASSAGE OF A FAST-MOVING MIDLATITUDE SHORTWAVE TROUGH TO THE
NORTH. DYNAMIC GUIDANCE IS IN CLOSER AGREEMENT BUT STILL SHOWS TWO
DISTINCT CLUSTERS. NAVGEM, GFDN, GFS AND COAMPS-TC TRACK THE SYSTEM
NORTHWESTWARD AND DECREASE THE TRACK SPEED WHILE UKMO,ECMWF AND THE
JGSM ENSEMBLE (JENS) TRACK THE SYSTEM FASTER AND MORE WESTWARD UNDER
THE STEERING INFLUENCE OF A BUILDING SUBTROPICAL RIDGE. THE JTWC
FORECAST FAVORS THE ECMWF, UKMO AND JENS SOLUTIONS AS THE MODEL
FIELDS INDICATE A ZONAL MIDLATITUDE PATTERN AND ALSO SHOW THE
FRONTAL SYSTEM QUICKLY TRANSITING EAST AWAY FROM STY 07E. STY 07E IS
FORECAST TO WEAKEN SIGNIFICANTLY AFTER TAU 72 AS IT ENCOUNTERS
COOLER SST (25-26C). OVERALL, THERE IS LOW CONFIDENCE (HIGH
UNCERTAINTY) IN THE FORECAST DUE TO THE LARGE MODEL SPREAD AND
RAPIDLY EVOLVING SYNOPTIC STEERING PATTERN IN THE EXTENDED PERIOD.//
