SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 06W (NIDA) WARNING
NR 05//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM (TS) 06W (NIDA), LOCATED APPROXIMATELY 258 NM EAST-
NORTHEAST OF MANILA, PHILIPPINES, HAS TRACKED NORTHWESTWARD AT 19
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS A CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC)
WITH IMPROVED DEEP CONVECTIVE BANDING WRAPPING INTO A CENTRAL DENSE
OVERCAST FEATURE. A 301009Z AMSU 89GHZ IMAGE INDICATES THAT THE LLCC
IS BECOMING MORE SYMMETRIC AND DEFINED. THE CURRENT INTENSITY IS
ASSESSED AT 40 KNOTS BASED ON AN AVERAGE OF DVORAK INTENSITY ESTIMATES
RANGING FROM T2.5 (35 KNOTS) TO T3.0 (45 KNOTS). OVERALL, ENVIRONMENTAL
CONDITIONS APPEAR CONDUCIVE WITH WARM SST (30 TO 31C), HIGH OCEAN HEAT
CONTENT VALUES, LOW VERTICAL WIND SHEAR AND GOOD DIFFLUENCE. TS 06W IS
CURRENTLY TRACKING ALONG THE WESTERN PERIPHERY OF THE LOW-LEVEL
SUBTROPICAL RIDGE (STR).
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TS 05W IS FORECAST TO TRACK NORTHWESTWARD TO WEST-NORTHWESTWARD
AS IT BEGINS TO TRANSITION TO THE STEERING INFLUENCE OF A DEEP STR
ENTRENCHED OVER EASTERN CHINA. THE SYSTEM IS FORECAST TO TRACK NEAR
HONG KONG AS IT TRACKS ALONG THE SOUTHERN
PERIPHERY OF THE STR. THE STR OVER EASTERN CHINA IS EXPECTED TO
REMAIN STRONG THROUGH TAU 72 DUE TO THE PRESENCE OF A STRONG HIGH
OVER MONGOLIA AND LACK OF ANY SIGNIFICANT MIDLATITUDE SHORTWAVE
TROUGHS. DYNAMIC GUIDANCE REMAINS IN TIGHT AGREEMENT, THEREFORE,
THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK, WHICH IS
POSITIONED NEAR BUT JUST SOUTH OF THE MODEL CONSENSUS. ENVIRONMENTAL
CONDITIONS ARE EXPECTED TO REMAIN FAVORABLE THEREFORE THE SYSTEM
SHOULD INTENSIFY TO A PEAK INTENSITY OF 75 KNOTS BY TAU 36 AND
PERHAPS HIGHER BEFORE MAKING LANDFALL NEAR HONG KONG BY TAU 60.
C. IN THE EXTENDED TAUS, TS 06W SHOULD WEAKEN RAPIDLY AS IT
TRACKS WESTWARD INTO CHINA AND WILL DISSIPATE NEAR TAU 96.//

It didn't look like an eye to me. Rather, it looked like an enhanced V signature of a prominent overshoot.

MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL DEPRESSION 06W (SIX) WARNING
NR 06//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM 06W (NIDA), LOCATED APPROXIMATELY 214 NM EAST-
NORTHEAST OF MANILA, PHILIPPINES, HAS TRACKED WEST-NORTHWESTWARD
AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
IMAGERY DEPICTS DEEP FLARING CENTRAL CONVECTION FORMING A DENSE
OVERCAST OBSCURING THE LOW LEVEL CIRCULATION CENTER (LLCC). THE
INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON A 301729Z
AMSR2 37 GHZ IMAGE SHOWING IMPROVING CONVECTIVE BANDING WRAPPING
TIGHTLY INTO THE LLCC. OTHER RECENT MICROWAVE IMAGERY CONFIRMS THE
POSITION AND A 301501Z GMI 37 GHZ IMAGE SHOWS VERY LITTLE MOVEMENT
IN THE LAST 3 HOURS. THE SUBTROPICAL RIDGE TO THE EAST PREVIOUSLY
STEERING TS 06W TO THE NORTH-NORTHWEST IS TRANSITIONING TO A WELL
ESTABLISHED DEEP-LAYER RIDGE TO THE NORTH; RESPONSIBLE FOR THE
RECENT DEACCELERATION AND ERRATIC TRACK OBSERVED OVER THE LAST 24
HOURS. THE CURRENT INTENSITY IS ASSESSED AT 45 KNOTS AND IS BASED ON
BOTH AUTOMATED AND OBJECTIVE DVORAK FIXES FROM MULTIPLE AGENCIES.
THE ENVIRONMENT IS BECOMING INCREASINGLY FAVORABLE WITH WIND SHEAR
VALUES NEAR 5 TO 10 KNOTS, SSTS IN EXCESS OF 30 CELSIUS WITH
SUBSTANTIAL OCEANIC HEAT CONTENT, AND A NEAR ANTICYCLONE FORMING
OVER THE SYSTEM.
3. FORECAST REASONING.
A. NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
PROGNOSTIC REASONING MESSAGE.
B. TS 06W IS EXPECTED TO ACCELERATE NORTHWESTWARD IN THE NEXT 12
HOURS AS THE STEERING RIDGE TO THE NORTH REORIENTS. INTENSITY IS
EXPECTED TO REACH 60 KNOTS BEFORE MAKING LANDFALL OVER LUZON AROUND
TAU 18. THE SYSTEM IS EXPECTED TO MAINTAIN ITS STRUCTURE FAIRLY WELL
AS IT INTERACTS WITH THE COASTLINE OF LUZON AND RESURFACES OVER
WATER IN THE SOUTH CHINA SEA. ANOTHER PERIOD OF INTENSIFICATION IS
EXPECTED AS TS 06W CONTINUES ON ITS NORTHWESTWARD TRACK, PEAKING AT
75 KNOTS. LANDFALL IS EXPECTED AROUND TAU 60 NEAR HONG KONG.
C. IN THE EXTENDED TAUS, TD 06W SHOULD WEAKEN RAPIDLY AS IT
TRACKS WESTWARD INTO CHINA AND WILL DISSIPATE BY TAU 96. DYNAMIC
MODEL GUIDANCE IS IN VERY TIGHT AGREEMENT AND HAS BEEN OVER THE LAST
24 HOURS SHOWING A WEST-NORTHWESTWARD TRACK UNDER THE INFLUENCE OF
THE DEEP LAYERED RIDGE ANCHORED OVER CHINA, AND EACH SOLUTION SHOWING
LANDFALL NEAR HONG KONG. SLIGHT DIFFERENCES IN THE SHORT-TERM
FORECAST TRACK ARE DUE TO THE UNEXPECTED ERRATIC TRACK OBSERVED OVER
THE LAST 24 HOURS AS THE PRIMARY STEERING RIDGE TRANSITIONS. THE
FORECAST TRACK IS PLACED NEAR THE MULTI-MODEL CONSENSUS TRACK. DUE
TO THE TIGHT AGREEMENT OF MODEL SOLUTIONS, THERE IS HIGH CONFIDENCE
IN THE FORECAST TRACK.//

OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS DEEP FLARING CENTRAL CONVECTION FORMING A COLD DENSE
OVERCAST OBSCURING THE LOW LEVEL CIRCULATION CENTER (LLCC). THE
INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON A 302241Z
SSMIS 91 GHZ IMAGE SHOWING A STRONG BAND OF CONVECTION ON THE
WESTERN PERIPHERY WRAPPING TIGHTLY INTO THE LLCC. CONVECTIVE
ACTIVITY AND WIND SPEEDS ARE CURRENTLY BEING INFLUENCED BY
INTERACTION WITH THE TOPOGRAPHIC FEATURES OF EASTERN LUZON. THE
INTENSITY IS ASSESSED AT 55 KNOTS AND IS BASED ON OBJECTIVE DVORAK
ESTIMATES FROM ALL AGENCIES REPORTING T3.5 (55 KNOTS). THE STEERING
MECHANISM FOR TS 06W IS CURRENTLY TRANSITIONING TO A SUBTROPICAL
RIDGE TO THE NORTH, AND THIS TRANSITION IS RESPONSIBLE FOR THE
DECREASE IN TRACK SPEED OVER THE LAST 12 HOURS. RECENT DATA SHOWS
THE SYSTEM HAS BEGUN ACCELERATING, SUGGESTING THE RIDGE IS BEGINNING
TO TAKE HOLD. THE ENVIRONMENT IS FAVORABLE WITH WIND SHEAR VALUES

B. TS 06W WILL CONTINUE TO ACCELERATE WEST-NORTHWESTWARD IN THE
NEXT 12 HOURS AS THE STEERING RIDGE TO THE NORTH REORIENTS.
INTENSITY IS EXPECTED TO INCREASE DUE TO THE FAVORABLE ENVIRONMENT,
BUT INTENSIFICATION WILL BE LIMITED AS THE SYSTEM SKIRTS THE
COASTLINE OF NORTHERN LUZON THROUGH TAU 18. THE SYSTEM IS EXPECTED

Making landfall over a remote area of Cagayan, Nida has reemerged back over water, the Babuyan Channel, southwest of Santa Ana...

It's currently tracking more south and west of the forecast track...

Though its structure was clearly disrupted by the terrain of Luzon, it still looks pretty good on sat imagery with a developing ragged eye.

Vicente looks worse when it was on the same location.
BTW, Vicente was the last storm where HKO hoisted Signal Number 10 in HongKong (There were only 14 instances since 1946)

Here is the latest Tropical Cyclone Bulletin issued by the Hong Kong Observatory.

The Standby Signal, No. 1 is in force.

This means that a tropical cyclone now centred within about 800 kilometres of Hong Kong may affect us.

At midnight, Severe Tropical Storm Nida was estimated to be about 750 kilometres east-southeast of Hong Kong (near 19.0 degrees north 120.5 degrees east) and is forecast to move northwest or west-northwest at about 25 kilometres per hour edging closer to the coast of Guangdong and intensifying gradually.

Nida does not look very impressive on satellite at the moment, and I wonder how much it can intensify prior to landfall. It will still be a significant threat to Hong Kong, though.
