I read somewhere cant remember where right now but it claims over water there is no real difference between 1min/10min its over land where there's friction is when it comes into play.

JMA's only presence is to the asian countries in the WPAC where they even have their own Meteorological Agency

Everyone knows that here.

What i meant is Guam is US Territory as far as i know by my way of thinking its a cat1 .If it was close to japan prolly been upgraded yesterday by the JMA .


It wouldn't matter on location. Dvorak already indicating a typhoon with an eye. Just because it's near a certain land doesn't mean a quicker upgrade to typhoon. You have valuable imagerys that can see through regular ones to reveal an eye, ASCAT, microwave and radar etc.

So based on this is now a typhoon.

JMA upgraded Tapah to 55 kts. I thought they'd upgrade to a typhoon or at least 65 kts.

Tapah has just peaked. It is forecast to weaken according to both JMA and JTWC due to unfavorable conditions along its path. No longer expecting a typhoon Tapah from JMA.

This is hilarious!

Tons of evidence including an eye but still only STS? What more do they want?

Official doesn't mean right...

Robert Speta even agreeing with JTWC...

Tapah has just peaked at 65 knots and expected to weaken from now on...



WDPN31 PGTW 291500
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TYPHOON 06W (TAPAH) WARNING NR 09//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TYPHOON (TY) 06W (TAPAH), LOCATED APPROXIMATELY 151 NM NORTHEAST
OF SAIPAN, HAS TRACKED NORTHWARD AT 08 KNOTS OVER THE PAST SIX
HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY AND A
291057Z METOP-B MICROWAVE PASS BOTH DEPICT A SLIGHTLY-WEAKENED DEEP
CONVECTION, YET CONVECTIVE BANDING REMAINS TIGHTLY-WRAPPED INTO THE
LOW-LEVEL CIRCULATION CENTER (LLCC). THE CURRENT POSITION IS
ASSESSED WITH HIGH CONFIDENCE BASED ON THE EIR ANIMATION, ABOVE
MICROWAVE IMAGE AS WELL AS A 291057Z ASCAT PASS SHOWING A WELL-
DEFINED LLCC. THE INITIAL INTENSITY OF 65 KNOTS IS BASED ON
CONGRUENT DVORAK CURRENT INTENSITY ESTIMATES FROM PGTW AND RJTD.
UPPER-LEVEL ANALYSIS INDICATES THE GOOD POLEWARD OUTFLOW PERSISTS;
HOWEVER, TY 06W HAS MOVED INTO A MARGINAL ENVIRONMENT WITH MODERATE
TO STRONG (20 TO 30 KNOT) VERTICAL WIND SHEAR (VWS) WHICH BEGINS TO
WEAKEN THE SYSTEM THROUGHOUT THE FORECAST PERIOD.
3. FORECAST REASONING.
A. NO CHANGE TO FORECAST PHILOSOPHY SINCE THE PREVIOUS PROGNOSTIC
REASONING MESSAGE.
B. TY 06W IS EXPECTED TO TURN NORTH-NORTHWESTWARD AS THE
SUBTROPICAL RIDGE TO THE EAST EXTENDS WESTWARD OVER THE NEXT 36
HOURS. BY TAU 48, THE SYSTEM WILL CREST THE RIDGE AXIS AND IS
FORECAST TO RE-CURVE NORTHEASTWARD AHEAD OF AN APPROACHING SHORTWAVE
TROUGH. BY TAU 72, THE COMBINED EFFECTS OF INCREASING VWS,
DIMINISHING OUTFLOW, AND COOLING SEA SURFACE TEMPERATURES WILL
SIGNIFICANTLY IMPACT THE SYSTEM AS IT CONTINUES TRACKING
NORTHEASTWARD.
C. FOR THE REMAINDER OF THE FORECAST PERIOD, UNFAVORABLE
CONDITIONS AND THE INTERACTION WITH THE COLD BAROCLINIC ZONE WILL
RAPIDLY WEAKEN THE SYSTEM, DISSIPATING IT BY TAU 96 OR EVEN SOONER.
THE DYNAMIC MODEL GUIDANCE REMAINS IN GOOD AGREEMENT, LENDING HIGH
CONFIDENCE IN THE JTWC TRACK FORECAST WHICH IS POSITIONED CLOSE TO
THE MULTI-MODEL CONSENSUS.//
