Typhoon Hunter, that is really an impressive radar imagery of Typhoon Saola...90 knots seems about right...very dangerous typhoon headed for taiwan which is already soaked and more flooding occuring...Taipei is in for a ride!

WDPN31 PGTW 011500
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TYPHOON 10W (SAOLA) WARNING NR 19//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TYPHOON 10W (SAOLA), LOCATED APPROXIMATELY 100 NM SOUTHEAST OF
TAIPEI, TAIWAN, HAS TRACKED NORTHWESTWARD AT 05 KNOTS OVER THE
PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS
COOLING CLOUD TOPS ASSOCIATED WITH BUILDING CONVECTION OVER THE
SOUTHERN PORTION OF THE LOW-LEVEL CIRCULATION CENTER (LLCC). THE
CURRENT POSITION IS BASED ON THE ABOVE MENTIONED IMAGERY WITH HIGH
CONFIDENCE. THE CURRENT INTENSITY IS BASED ON DVORAK ESTIMATES OF
90 KNOTS FROM PGTW, KNES, AND RJTD. UPPER-LEVEL ANALYSIS INDICATES
A POINT SOURCE OF DIVERGENCE DIRECTLY OVER THE SYSTEM WHICH IS
PROVIDING FOR WEAK (05-10 KNOTS) VERTICAL WIND SHEAR AND EXCELLENT
DIVERGENCE ALOFT. ANIMATED WATER VAPOR IMAGERY SHOWS ROBUST
EQUATORWARD OUTFLOW AND POLEWARD OUTFLOW CONTINUES TO SPREAD
NORTHWARD. INDUCED UPPER-LEVEL TROUGHING RESIDES IN BETWEEN THE
SYSTEM AND AN EXTENSION OF THE SUBTROPICAL RIDGE FURTHER TO THE
WEST. A 011246Z AMSU 89 GHZ IMAGES REVEALS THE DEEPEST CONVECTION
IS OVER THE SOUTHWESTERN QUADRANT OF THE LLCC. THIS ASYMMETRY IN
CONVECTION COMBINED WITH STRONG (60 KNOT) 500 MB SOUTHEASTERLY
FLOW, EVIDENT IN THE 011200Z ISHIGAKIJIMA SOUNDING, CAN ACCOUNT FOR
THE RECENT TRACK MOTION TOWARDS THE NORTHWEST. THIS SOUNDING, ALONG
WITH OTHERS IN THE AREA, CONFIRMS THAT TY 10W IS NOW STEERING ALONG
THE SOUTHWESTERN PERIPHERY OF THE BUILDING SUBTROPICAL RIDGE
CENTERED OVER JAPAN.
3. FORECAST REASONING.
A. THERE IS NO SIGNIFICANT CHANGE TO THE FORECAST PHILOSOPHY
FROM THE PREVIOUS PROGNOSTIC REASONING.
B. TY 10W IS FORECAST TO GRADUALLY INCREASE IN TRACK SPEED IN A
GENERAL NORTHWESTWARD DIRECTION UNDER THE INFLUENCE OF THE STR FOR
THE REMAINDER OF THE FORECAST PERIOD. INTENSIFICATION SHOULD
CONTINUE UNDER FAVORABLE UPPER-LEVEL AND SEA SURFACE CONDITIONS
ALLOWING TY 10W TO PEAK AT 95 KNOTS BY TAU 12. LANDFALL IS EXPECTED
BETWEEN TAUS 24 AND 36 AND GRADUAL DETERIORATION OF THE LLCC WILL
OCCUR THROUGH TAU 72 WHERE IT WILL HAVE DISSIPATED OVERLAND. MODEL
GUIDANCE IS TIGHTLY GROUPED UP TO LANDFALL WITH THE EXCEPTION OF
THE GFDN WHICH REMAINS THE RIGHT MOST OUTLIER. THE TRACK FORECAST
IS IN AGREEMENT WITH THE MODEL CONSENSUS UP TO TAU 36 WHERE IT THEN
REMAINS SLIGHTLY LEFT OF AND SLOWER TO OFFSET THE GFDN. THERE IS
HIGH CONFIDENCE IN THE TRACK FORECAST BASED ON THE TIGHT MODEL
ENVELOPE WHILE OVER WATER.//

Well, it is 85 knots now from the NRL... As it is now near the coast of Hualien County, it is impossible to become a category 3 typhoon at all.

News article about Typhoon Saola and the impact on Taiwan
http://www.washingtonpost.com/world/asi ... story.html

Points of Interest:
Typhoon Saola, which killed at least 14 people in the Philippines, has already been blamed for four deaths in Taiwan, with the toll expected to rise.

Authorities ordered offices and businesses closed throughout northern Taiwan, including in Taipei. Normally busy streets in the capital were deserted during the morning rush hour, as cleanup crews labored to clear them of hundreds of trees and branches felled during the night by Saola’s ferocious approach.

Dozens of flights were canceled at Taipei’s main international airport, and rail transport throughout the island was disrupted.

So, now Taiwan is 'enjoying' a Typhoon Holiday and we clean up & check on neighbors, there remains only one question: How can (all) the models have the track so wrong? What happened to cause that abrupt left turn late last night?

An excellent question and I do not have answers but I will state that this is the second major typhoon recently for which the models were wrong
Typhoon Vicente "bombed" and made landfall near Macau

i believe the topography of Taiwan may have contributed to that wobble... i posted about two days ago how models were suggesting continuous formation of weak vortices west and southwest of Taiwan... this may have pulled in the system closer to the coast--clearly observed on radar last night.. we've seen this time and again how systems meander just east of Taiwan, and some even make loops as they interact with the island.. right now, the LLCC seems to have moved back to the ocean and should slowly begin to inch northwestward...

i believe lee cyclogenesis is the right term (?)

Impressive amount of rainfall, even in central Taiwan. My in-laws in Taichung usually don't see much impact from typhoons but they got drenched. Highest rain total I have seen so far is 1,044mm in Taipingshan (太平山) in Yilan county. My retirement plan was to buy a house along the east coast of Taiwan somewhere but every year I lean more towards living on the other side of the mountains. Tough choice!
