REMARKS:
220300Z POSITION NEAR 18.9N 124.7E. TYPHOON 22W (LUPIT), LOCATED
APPROXIMATELY 340 NM NORTHEAST OF MANILA, PHILIPPINES, HAS TRACKED
WEST-SOUTHWESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. THE SYSTEM
REMAINS IN A WEAK STEERING ENVIRONMENT TRANSITIONING BETWEEN THE
SUBTROPICAL RIDGE (STR) TO THE EAST AND THE STR TO THE WEST.
ANALYSIS SHOWS NORTHWESTERLY FLOW BEGINNING TO WEAKEN THE WESTERN
RIDGE WHICH MAY ALLOW FOR THE STR TO THE EAST TO BECOME THE DOMINANT
INFLUENCE. NUMERICAL MODEL GUIDANCE HAS BEEN ERRATIC AND CURRENTLY
OVERWHELMINGLY FAVORS A POLEWARD TURN BY TAU 24. HOWEVER, CURRENT
ENVIRONMENTAL ANALYSIS OF THE REGION DOES NOT REVEAL A CLEAR PICTURE
OF THE SYNOPTIC STEERING FLOW. IT IS LIKELY THAT THE SYSTEM WILL
REMAIN IN A WEAK ENVIRONMENT THROUGH THE NEXT FEW DAYS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 220000Z IS 30 FEET. NEXT WARNINGS AT
220900Z, 221500Z, 222100Z AND 230300Z.//

You're quite right about the "fun" and "lot of next times" part. Me, I just caught interest in met just after Ondoy (Ketsana) hit the metro, and here I am, going crazy figuring out what Lupit would do and can't get enough of it.

I guess if I weren't in dialysis treatment, I could go storm-chasing just for the hell of it.. 8-)


I became fascinated w/ typhoons when I was young...I believe this is because of Super Typhoon Angela in 1995......We were practically at the direct path of the thing....I believe it's the strongest typhoon to ever hit the country...

Ok, but then why is the storm still moving SW? I'm not doubting you, just worried...

Thanks for the image and annotation, ozonepete. So if I'm reading this right, Lupit would eventually turn and blown NE?


That's the most likely scenario. But remember that the image I showed is the way conditions are now. In forecasting, it is much more important in getting a good handle on what's to come. That is where meteorology has a long way to go. From other prognostications I can look at, it does seem more likely that LUPIT will get caught in that eastern ridge flow in the next 12-24 hours.

Here's a chart of the current steering flow for storms of the calibre of LUPIT. It's from CIMSS, a weather forecasting/research group from the University of Wisconsin here in the U.S. They are an extremely talented group.

I just got the latest text explanation from the JTWC. Look at this:

REMARKS:
220300Z POSITION NEAR 18.9N 124.7E. TYPHOON 22W (LUPIT), LOCATED APPROXIMATELY 340 NM NORTHEAST OF MANILA, PHILIPPINES, HAS TRACKED WEST-SOUTHWESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. THE SYSTEM

NUMERICAL MODEL GUIDANCE HAS BEEN ERRATIC AND CURRENTLY OVERWHELMINGLY FAVORS A POLEWARD TURN BY TAU 24. HOWEVER, CURRENT ENVIRONMENTAL ANALYSIS OF THE REGION DOES NOT REVEAL A CLEAR PICTURE OF THE SYNOPTIC STEERING FLOW. IT IS LIKELY THAT THE SYSTEM WILL REMAIN IN A WEAK ENVIRONMENT THROUGH THE NEXT FEW DAYS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 220000Z IS 30 FEET. NEXT WARNINGS AT 220900Z, 221500Z, 222100Z AND 230300Z.//
NNNN

They're saying that most of the models now forecast the western STR to weaken and the flow of the eastern STR to get dominance over the storm. That would mean LUPIT should move to the north within 24 hours. I knew they would come around.

But that could be REALLY bad for N. Luzon? It could mean alot of rain for the north provinces, right?

That is a tiny, insignificant amount. Those are changes of 1/10 of a degree. The storm has been basically stationary, which JTWC is finally willing to take into consideration.

No, not if the storm remains nearly stationary and then moves north. Most of the heaviest rainfall will never get over the country.

We had a lot of rainfall, here, last night. Wow...so this may not look good for us then? Anyone have any guesses on how much or IF this storm would strengthen when it starts making its way back North? I'm wondering what we could expect on Okinawa.

For October storms, it may be true that the heaviest rains will miss Luzon, however, I call your attention to the track of STY Rita in the 1972 ATCR from JTWC and note that Clark AB received 89 inches of rain during the duration of that storm which never hit the Philippines also TY Mary in August 1974 which caused flooding rains in Luzon. Storms do not have to hit Luzon to cause rain problems there. STY Angela was the strongest storm to hit the Bicol region and Manila but I think there have been stronger ones up north.

So Steve, you are saying optimistic caution is still best? Thank you BTW for your comment.

Great advice, Steve. There have been disastrous rains from "nearby" typhoons or huricanes that never made landfall. that's why I said earlier that you can't let up your guard until the last advisory and your LOCAL office says all is clear.

Most of the models now move it pretty sharply northeast out to sea. You look in the clear for now.
