Las agencias tiene un consensus, posibile impactando a Luzon Central (practicing my Spanish :D )

Now trending away from a recurve which MU/GFS predicted

MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/PROGNOSTIC REASONING FOR TROPICAL STORM 06W (NOUL) WARNING NR
07//
RMKS//
1. FOR METEOROLOGISTS.
2. 6 HOUR SUMMARY AND ANALYSIS.
TROPICAL STORM 06W (NOUL), LOCATED APPROXIMATELY 95 NM EAST OF
YAP, HAS TRACKED WEST-SOUTHWESTWARD AT 03 KNOTS OVER THE PAST SIX
HOURS. THE CURRENT POSITION IS BASED ON RECENT MICROWAVE SATELLITE
DATA INCLUDING A 040923Z SSMIS PASS AND A 041141Z METOP-B IMAGE.
THE INTENSITY OF 45 KNOTS IS CONSISTENT WITH DVORAK SATELLITE
ESTIMATES FROM MULTIPLE REPORTING AGENCIES AS WELL AS SCATTEROMETER
DATA FROM A 041141Z ASCAT PASS. TS 06W HAS TRACKED SLOWLY WEST-
SOUTHWESTWARD UNDER THE STEERING INFLUENCE OF WEAK SUBTROPICAL
RIDGING TO THE NORTH OVER THE PAST SIX HOURS. DEEP CONVECTION HAS
INCREASED OVER A TIGHTLY-WRAPPED BAND SITUATED ALONG THE WESTERN
PERIPHERY OF THE LOW LEVEL CIRCULATION CENTER. MODERATE EASTERLY
VERTICAL WIND SHEAR AND A FAVORABLE OUTFLOW PATTER CONTINUES TO
INFLUENCE THE SYSTEM, WHICH IS SITUATED EQUATORWARD OF AN UPPER-
LEVEL RIDGE AXIS.
3. FORECAST REASONING.
A. THERE IS NO SIGNIFICANT CHANGE TO THE FORECAST PHILOSOPHY FROM
THE PREVIOUS WARNING.
B. TS 06W IS EXPECTED TO TRACK SLOWLY WESTWARD OVER THE NEXT 36
HOURS UNDER THE CONTINUED STEERING INFLUENCE OF SUBTROPICAL RIDGING
TO THE NORTH. AFTER TAU 36, THE SUBTROPICAL RIDGE IS EXPECTED TO
BUILD AND REORIENT AS A MID-LATITUDE TROUGH THAT HAS WEAKENED RIDGE
MOVES EASTWARD. THIS REORIENTED RIDGE WILL ACCELERATE THE SYSTEM
ALONG A WEST-NORTHWESTWARD TRAJECTORY. THE CYCLONE SHOULD STEADILY
INTENSIFY OVER THE NEXT 72 HOURS DUE TO PASSAGE OVER VERY WARM WATER
AND MODERATELY FAVORABLE UPPER-LEVEL CONDITIONS. NUMERIC MODEL
GUIDANCE IS IN FAIR AGREEMENT THROUGH TAU 72. THERE IS SOME
DIVERGENCE AMONG SOLUTIONS, BUT ALL MODELS WITH THE EXCEPTION OF
GFDN INDICATE A WESTWARD TO WEST-NORTHWESTWARD TRACK OVER OR
SLIGHTLY TO THE NORTH OF YAP. THE CURRENT JTWC FORECAST LIES CLOSE
TO THE MULTI-MODEL CONSENSUS, NEAR THE CENTER OF THE PRIMARY MODEL
GROUPING.
C. IN THE EXTENDED PERIOD, TS 06W IS EXPECTED TO MOVE WEST-
NORTHWESTWARD INTO THE PHILIPPINE SEA. THE SYSTEM SHOULD MAINTAIN
INTENSITY OR PERHAPS INTENSIFY FURTHER AS ENVIRONMENTAL CONDITIONS
REMAIN GENERALLY FAVORABLE. MODEL TRACK FORECAST SOLUTIONS DIVERGE
MORE NOTICEABLY AFTER TAU 72, WITH A GROUPING CONSISTING OF GFS,
GEFS, HWRF, AND COAMPS-TC DEPICTING A MORE POLEWARD TRACK AND A
SECOND GROUPING CONSISTING OF ECMWF, NAVGEM, THE UKMET MODEL, AND
THE JAPANESE TC-EPS DEPICTING A FLATTER TRACK TO THE WEST-NORTHWEST.
THE CURRENT FORECAST FAVORS THE LATTER GROUPING BASED ON ANTICIPATED
EVOLUTION OF THE SUBTROPICAL STEERING RIDGE. HOWEVER, GIVEN CURRENT
MODEL SPREAD, THERE IS LOW CONFIDENCE IN THE JTWC TRACK FORECAST.//

Low chance next 24 hours.

AN AREA OF CONVECTION HAS PERSISTED NEAR 5.4N 156.0E,
APPROXIMATELY 160 NM SOUTHWEST OF POHNPEI. ANIMATED MULTISPECTRAL
IMAGERY DEPICTS AN INTENSIVE AREA OF DEEP CONVECTION ASSOCIATED WITH
AN ILL-DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC). A 042021Z SSMIS
REVEALS FRAGMENTED CONVECTIVE BANDING BROADLY WRAPPING INTO THE
LLCC. UPPER-LEVEL ANALYSIS INDICATES THE DISTURBANCE IS LOCATED IN A
MARGINALLY-FAVORABLE ENVIRONMENT WITH LOW TO MODERATE VERTICAL WIND
SHEAR AND GOOD DIFFLUENCE ALOFT. ADDITIONALLY, WARM SEA SURFACE
TEMPERATURES ARE CONDUCIVE FOR DEVELOPMENT. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.

Similar storm to this was Ruby 1988. Caused significant flooding over Luzon particularly the capital Manila

System appears to be almost stalling as per the GFS forecast solution before the recurve.

But never predicted the SW jog too :lol: So, maybe not a recurve for now. Agencies in WPAC in general agreement on Central Luzon impact. Moving at 11 kph so not stalling

The recurve as depicted by the computer models and agency forecast tracks is too close for comfort for PI. A slight nudge can make a difference, besides a cyclone isn't just a dot to affect only those along the trackline. The east coast of Luzon could be affected and should keep an eye on it IMO.

Why would it recurve? :roll: Wouldn't the ridge rebuild? It would steer the system more westwards the more powerful it becomes and the break would make a slight NW turn before resuming its normal track. What is likely is that the Philippines would still have at least moderate impact.

Maybe something like Rammasun 2014 but like Ivan 1997, which would mean the best analog typhoon for both track and intensity would be Ruby 1988 as mentioned.

IMO and its amateur like yours is to this system's center wont make landfall in the PI.



I get it, we all have our insights (amateur or sounded) and we are responsible not to wishcast nor to show lack of vigilance in our own forecasts. My only point is that based on available model guidance, the likely point of recurve (if the recurve scenario pans out) is still quite close to land and the east coast of Luzon could still see some nasty weather, whether it makes landfall or not..just my amateur insight. :)

I can't say this will be similar to Ruby 1988 trackwise given the time of year when it occurred (STR in North Asia is somehow weaker at this point compared to last quarter of the year, plus the ongoing El Nino episode tends to have stronger digging troughs, resulting the weaker STR)
