Yeah this is the one that GFS has been consistently developing for a week now. It also shows on other models including ECMWF. They only differ by strength of this system.

Last night's 12z model has it back to Bicol-CALABARZON-Manila. It has been consistent with that over the last few days runs.

Manila hasn't been hit by a Major (Cat3 above) Typhoon since Milenyo in 2005.

Did u mean 2006? There was no storm that hit Manila last 2005.

Anyways, we have to be careful and DON'T PANIC. PANIC may cause chaos there in Manila!

[OFF TOPIC: We experienced a 5.2 magnitude aftershock. It was Intensity V on the MIS.]

GFS shifts further south. Making landfall in Southern Samar, traversing over Northern Cebu, Panay. Reminds me of FENGSHEN/FRANK last 2008, except that this will hit Southern Vietnam and ''will be a powerful cyclone over the Indian Ocean'' - NOT FINAL .

I guess this might shift to the south again, but the main thing is that, VISAYAS - we - ARE still experiencing powerful aftershocks!

Shifts in model tracks don't matter as long as an actual cyclone hasn't formed yet. But even in that track, CALABARZON area will still be in the northern periphery of a strong typhoon. That's still some nasty scenario for areas from Southern Luzon down to Visayas. Bicol hasn't seen a strong typhoon since Durian in 2006. Definitely keeping an eye on this one!

Guess what guys and gals, it has now been upgraded to MEDIUM!

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 5.4N
161.7E, IS NOW LOCATED NEAR 6.1N 158.6E, APPROXIMATELY 45 NM SOUTH-
SOUTHEAST OF POHNPEI, FSM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
REVEALS A BROAD LLCC WITH RAPIDLY CONSOLIDATING FORMATIVE BANDS.
UPPER-LEVEL ANALYSIS INDICATES THE SYSTEM IS JUST SOUTH OF A
SUBTROPICAL HIGH IN AN AREA OF LOW VWS AND EXCELLENT RADIAL OUTFLOW
WITH A STRONG EQUATORWARD CHANNEL. SSTS IN THE AREA ARE PERENNIALLY
WARM (28 TO 30 DEGREES CELSIUS) FOR DEVELOPMENT. DYNAMIC MODELS
INDICATE THE DEVELOPMENT OF A WELL-ORGANIZED TROPICAL CYCLONE WITHIN
THE NEXT 48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1006 MB. IN VIEW OF THE IMPROVED ENVIRONMENT, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.

this invest really looks seriously ominous.
my guess... it will add up 20+ ACE points.. and that's very conservative

What's interesting is that the bulk of the GFS ensemble members has the track passing through batangas and Cavite provinces while the deterministic GFS track is on the southern edge of the ensemble. Anyway this looks to be a really threatening system for the Philippines.

99W is moving west, too far to affect your area. Models are already shifting south...
