SUBJ/PROGNOSTIC REASONING FOR TYPHOON 10W (MARIA) WARNING NR
30//
RMKS/
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TYPHOON (TY) 10W (MARIA), LOCATED APPROXIMATELY 153 NM SOUTH-
SOUTHWEST OF KADENA AB, HAS TRACKED WEST-NORTHWESTWARD AT 15 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS GRADUAL WEAKENING OF DEEP CONVECTION WITH A 30NM
OBLONG EYE, WHICH PROVIDES GOOD CONFIDENCE IN THE CURRENT POSITION.
A 092201Z SSMIS 91GHZ IMAGE REVEALS CONCENTRIC RINGS AND A DEFINED
MOAT INDICATIVE OF THE ONGOING EYEWALL REPLACEMENT CYCLE. THE
INITIAL INTENSITY IS ASSESSED AT 110 KNOTS BASED ON THE DVORAK
CURRENT INTENSITY ESTIMATES FROM KNES AND PGTW RANGING FROM 5.5 TO
6.0 (102-115 KNOTS) AND A SATCON ESTIMATE OF 106 KNOTS. THE 10/0110Z
ADVANCED DVORAK TECHNIQUE ESTIMATE IS SLIGHTLY LOWER AT 5.2 (95
KNOTS). UPPER-LEVEL ANALYSIS INDICATES NEAR-RADIAL OUTFLOW,
HOWEVER, POLEWARD OUTFLOW HAS WEAKENED OVER THE PAST 24 HOURS.
ADDITIONALLY, SST VALUES HAVE COOLED SLIGHTLY AS WELL AS A
SIGNIFICANT DECREASE IN OCEAN HEAT CONTENT VALUES. TY MARIA IS
CURRENTLY TRACKING WEST-NORTHWESTWARD ALONG AN EXTENSION OF THE DEEP
LAYERED SUBTROPICAL RIDGE (STR) WHICH IS LOCATED TO THE NORTHEAST.
3. FORECAST REASONING.
A. THERE IS NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE
PREVIOUS PROGNOSTIC REASONING MESSAGE.
B. TY 10W IS FORECAST TO CONTINUE TRACKING WEST-NORTHWESTWARD
ALONG THE SOUTHWESTERN EXTENSION OF THE AFOREMENTIONED STR. TY 10W
IS FORECAST TO WEAKEN SLOWLY THROUGH TAU 12 UNDER GENERALLY
FAVORABLE CONDITIONS. AFTER TAU 12, THE SYSTEM IS EXPECTED TO WEAKEN
SIGNIFICANTLY, AS IT TRACKS JUST NORTH OF TAIWAN, DUE TO INCREASING
FRICTIONAL EFFECTS. TY MARIA WILL MAKE LANDFALL NEAR TAU 24 AND WILL
WEAKEN RAPIDLY AS IT RECURVES OVER EASTERN CHINA WITH DISSIPATION
FORECAST BY TAU 72. NUMERICAL MODEL GUIDANCE REMAINS IN TIGHT
AGREEMENT, THEREFORE, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST
TRACK.//

1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TYPHOON (TY) 10W (MARIA), LOCATED APPROXIMATELY 165 NM SOUTHWEST
OF
KADENA AB, OKINAWA, JAPAN, HAS TRACKED WEST-NORTHWESTWARD AT 16
KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
(MSI) SHOWS THE SYSTEM HAS MAINTAINED A LARGE AND RAGGED 30-NM EYE,
THE RESULT OF A PREVIOUS EYE WALL REPLACEMENT. SPIRAL BANDS HAVE ALSO
REMAINED TIGHTLY WRAPPED AND FEEDING INTO THE EYE WITH MINOR SIGNS OF
FRAGMENTATION AND WARMING ALONG THE CONVECTIVE TOPS. THE INITIAL
POSITION IS PLACED WITH HIGH CONFIDENCE SLIGHTLY BEHIND THE EYE
FEATURE IN THE MSI LOOP TO ACCOUNT FOR A SMALL SLANT AS EVIDENCED BY
A WELL-DEFINED MICROWAVE EYE IN THE 100449Z ATMS PASS SLIGHTLY
TRAILING THE 100450Z 1KM VIS EYE. THE INITIAL INTENSITY OF 110 KNOTS
IS BASED ON AN OVERALL ASSESSMENT OF AGENCY AND OBJECTIVE DVORAK
ESTIMATES. UPPER-LEVEL ANALYSIS INDICATES NEAR-RADIAL OUTFLOW WITH A
WEAKENING POLEWARD CHANNEL. ALONG-TRACK SST VALUES REMAIN WARM AND
CONDUCIVE AT 29 CELSIUS. THE CYCLONE IS TRACKING ALONG AN EXTENSION
OF THE DEEP-LAYERED SUBTROPICAL RIDGE (STR) THE NORTHEAST.
3. FORECAST REASONING.
A. THERE IS NO CHANGE TO THE FORECAST PHILOSOPHY SINCE THE
PREVIOUS PROGNOSTIC REASONING MESSAGE.
B. STEERED BY THE STR, TY MARIA IS FORECAST TO CONTINUE TRACKING
WEST-NORTHWESTWARD FOR THE REMAINDER OF THE FORECAST. AS OUTFLOW
WEAKENS AND SSTS BEGIN TO COOL, THE SYSTEM WILL GRADUALLY WEAKEN AND
NEAR TAU 18, AFTER IT MAKES LANDFALL NEAR FOZHOU, CHINA, WILL RAPIDLY
ERODE AS IT TRACKS ACROSS THE RUGGED TERRAIN OF INLAND CHINA. BY TAU
48, IT WILL BE REDUCED TO A 30-KNOT DEPRESSION OVER LAND. NUMERICAL
MODEL GUIDANCE REMAINS IN TIGHT AGREEMENT, THEREFORE, THERE IS HIGH
CONFIDENCE IN THE JTWC FORECAST TRACK.//

Impressive...
Closeup of the expected landfall. Now zeroing on +2.8 million Ningde. Not far north from Fuzhou.

Re: WPAC: MARIA - Typhoon
I think Maria is attempting to go Annular before landfall - I don't know if she had enough time to pull the trick but what I'm sure is that she carries a massive storm surge potential- she has the size, strength, speed, right angle of approach and favorable bathymetry.

Re: WPAC: MARIA - Typhoon
Not sure if this is a major hurricane anymore but regardless, this poses a 3 way storm threat of surge, winds, and flooding rains. Eyewall starting to brush the China coastline.

1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TYPHOON (TY) 10W (MARIA), LOCATED APPROXIMATELY 76 NM NORTH-
NORTHEAST OF TAIPEI, TAIWAN, HAS TRACKED WEST-NORTHWESTWARD AT 19
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY DEPICTS A GRADUAL WEAKENING SYSTEM WITH DEEP
CONVECTIVE BANDING WRAPPING AROUND A 30NM OBLONG EYE. EIR ALSO
INDICATES SOME EROSION OF DEEP CONVECTION OVER THE SOUTHWEST
QUADRANT DUE TO THE INITIAL INTERACTION WITH TAIWAN. OVERALL, THERE
IS GOOD CONFIDENCE IN THE INITIAL POSITION. THE INITIAL INTENSITY IS
ASSESSED AT 100 KNOTS BASED ON DVORAK CURRENT INTENSITY ESTIMATES OF
5.5 (102 KNOTS) FROM BOTH PGTW AND RJTD. UPPER-LEVEL ANALYSIS
INDICATES RADIAL OUTFLOW, HOWEVER, TY 10W CONTINUES TO WEAKEN DUE TO
INCREASING NORTHERLY VERTICAL WIND SHEAR (15 TO 20 KNOTS), SLIGHTLY
COOLER SST (28C) AND VERY LOW OCEAN HEAT CONTENT VALUES. TY MARIA IS
CURRENTLY TRACKING ALONG THE SOUTHWEST PERIPHERY OF THE DEEP-LAYERED
SUBTROPICAL RIDGE (STR).

Re: WPAC: MARIA - Typhoon
Using the lowest pressure from Miyakojima that I found (945 mb), I end up with a range from 95 kt (background pressure adjusted AH77) to 105 kt (KZC). The one place where I've found AH77 to shine is in concentric eyewall situations, hence its use here. Wind reports definitely seemed on the lower end of the spectrum (highest gust I saw was only about 88 kt). I probably wouldn't go any higher than 95 kt for the intensity when Maria crossed Miyakojima, which was around 06Z yesterday.
