Re: WPAC: NANMADOL - Typhoon (14W/Mina)
So the eye just moved inland to Cagayan. Been "patrolling" through Facebook and I saw updates stating that winds are already nasty in places far from the point of landfall like Baguio and Ilocos region. I just couldn't believe that these areas are only under Signal #1 (only TD-condition expected). Here in the metro, rains continue to pour with some gusty winds. I wish everyone has prepared well in spite of just a day given for preparation.
I can remember earlier this week, this storm was projected to move northwards all the way but see things have changed by then. Not blaming any agencies though, I understand that long-range forecasts tend to change, given the existing complex setup (possible Fujiwara effect and monsoon gyre). It's just that the agencies in the Philippines might need a day longer to get ready for evacuation procedures and others.

Nanmadol was kinda influenced by the topography of Luzon in terms of movement--sort of like what we usually see with typhoons suddenly becoming erratic once they reach the eastern coast of Taiwan... remember that we have numerous mountain ranges in Luzon as well--the closest to the Pacific being the Sierra Madre... simply put, this features can sort of like pull in the storm towards land--a movement that is not usually handled well by computer models...
based on the latest forecasts we could see this scenario repeating itself once Nanmadol reaches Taiwan... numerous models show a big time slowdown in speed as well as the movement becoming erratic.. GFS kinda downplays it as it still brings Nanmadol eventually northeastward... the rest puts Nanmadol towards the middle of Taiwan or at least brings it more to the north...
anyway... Laoag Airport which is about 150km southwest of Nanmadol has reported NNW (340) winds at 14 gusting to 30kts... pressure down to 996mb..

Yeah also here in Manila! Well I really have this feeling that this is a direct effect of Nanmadol's outer bands and not only because of enhanced SW monsoon because if it weren't, winds will not appear to be like this and the winds are coming from the northwest.

The wind is probably an effect of nanmadol...The rain on the other hand is most likely the effect of the SW monsoon...

TYPHOON (TY) 14W (NANMADOL), LOCATED APPROXIMATELY 580 NM SOUTH-
SOUTHWEST OF KADENA AB, OKINAWA, HAS TRACKED NORTHWESTWARD AT 03
KNOTS OVER THE PAST SIX HOURS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
270000Z IS 34 FEET. NEXT WARNINGS AT 270900Z, 271500Z, 272100Z AND

SUBJ/PROGNOSTIC REASONING FOR TYPHOON 14W (NANMADOL) WARNING NR 18//
RMKS/
1. FOR METEOROLOGISTS.
2. 12 HOUR SUMMARY AND ANALYSIS.
A. TYPHOON (TY) 14W (NANMADOL), LOCATED APPROXIMATELY 580 NM
SOUTH-SOUTHWEST OF KADENA AB, OKINAWA, HAS TRACKED NORTHWESTWARD AT
03 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS THAT LAND INTERACTION WITH LUZON HAS CAUSED THE EYE TO
BECOME CLOUD-FILLED WHILE THE EYEWALL ALONG THE NORTHERN SEMICIRCLE
HAS ERODED. A 262219Z SSMIS MICROWAVE IMAGE SHOWS THAT THE LOW LEVEL
CIRCULATION CENTER IS JUST SEAWARD OF THE NORTHEASTERN TIP OF LUZON,
WITH THE EASTERN HALF OF THE STORM REMAINING WELL ORGANIZED WITH
ABUNDANT DEEP CONVECTION. ANIMATED WATER VAPOR IMAGERY CONFIRMS THE
POLEWARD OUTFLOW CHANNEL IS STILL OPEN OVER THE NORTHEASTERN
QUADRANT, AND OUTFLOW IN THE OTHER QUADRANTS REMAINS VIGOROUS. TY
14W IS BEING NUDGED TO THE NORTHWEST BY THE WESTWARD EXTENSION OF
THE NEAR EQUATORIAL RIDGE.
3. FORECAST REASONING
A. THERE IS NO CHANGE TO THE FORECAST PHILOSOPHY.
B. THE NEAR EQUATORIAL RIDGE WILL BUILD OVER THE PHILIPPINE SEA
DURING THE NEXT 72 HOURS AND REMAIN THE DOMINANT STEERING INFLUENCE.
THE RIDGE WILL GUIDE TY 14W TOWARDS THE EAST COAST OF TAIWAN. ALONG-
TRACK ENVIRONMENTAL CONDITIONS ARE FAVORABLE FOR RE-INTENSIFICATION.
VERTICAL WIND SHEAR, CURRENTLY ASSESSED AT JUST 08 KNOTS, WILL
WEAKEN FURTHER OVER THE LUZON STRAIT, WHILE SEA SURFACE TEMPERATURES
WILL AVERAGE 31 DEGREES CELSIUS. THUS, TY 14W WILL RE-INTENSIFY
DURING THE NEXT 24 HOURS AS IT CLEARS THE LAND IMPEDIMENTS OF LUZON,
THEN WEAKEN AGAIN AS IT APPROACHES TAIWAN. THE EFFECTS OF LAND
INTERACTION WITH TAIWAN WILL BECOME EVIDENT BY TAU 36.
C. AFTER TAU 72, TY 14W WILL ENCOUNTER COMPETING STEERING
INFLUENCES BETWEEN THE NEAR EQUATORIAL RIDGE AND AN UPPER LEVEL
ANTICYCLONE SETTLING JUST WEST OF KYUSHU. ECMWF AND JGSM MOVE THE
SYSTEM ACROSS THE TAIWAN STRAIT AND TO LANDFALL OVER EASTERN CHINA,
WHILE THE REMAINDER OF THE TRACKERS KEEP TY 14W EAST OF TAIWAN. THE
JTWC TRACK FORECAST STAYS CLOSE TO CONSENSUS, WHICH PRESENTS A GOOD
MEAN BETWEEN THE DISPARATE MODEL SOLUTIONS. THE ENVIRONMENTAL
CONDITIONS ALONG THE TRACK WILL REMAIN HIGHLY FAVORABLE FOR
DEVELOPMENT, BUT LAND INTERACTION WITH TAIWAN WILL MITIGATE THOSE
FACTORS.//

Re: WPAC: NANMADOL - Typhoon (14W/Mina)
I understood all the previous tracks a couple of days ago had Nanmadol heading north towards Okinawa, yet is tracker WNW and hit the northern most tip of Philippines. So is it possible it continues on this track and actually heads towards the coast of China to the West of Taiwan instead or heading towards Taiwan?

Re: WPAC: NANMADOL - Typhoon (14W/Mina)
Amazing what a brush with with land can do...from a perfect
eye..
too this..phillippines did a decent number on Nanmadol and
may have spared Taiwan an even bigger hit in intensity.
