I just think these are a cluster of storms between 96 and 97 but im not a pro so i could be wrong..lol

[KWT]

Yeah this area really isn't impressive, not too sure what they are tracking to be honest!

[Typhoon10]

PAGASA is now saying that 96 and 97W have merged and developed into a Tropical Storm!!!

There is nothing there from a brief look, what on earth are they playing at?

Residents living in low lying and mountainous areas under signal # 1 & 2 are alerted against possible flashfloods and landslides.

Tropical Storm Domeng has enhanced the Southwest Monsoon that will generate moderate to rough seas as well as bring rains which may also trigger flashfloods and landslides in other areas of the country.

The public and the disaster coordinating councils concerned are advised to take appropriate actions and watch for the next bulletin alert to be issued at 11 PM today.

*****************************************
I was expecting that PAGASA will just let this system to be a tropical depression (since they are the ONLY agency classifying this as one). Now, this surprised me even more. They even upgraded it to a TS and stated the merging of a low pressure area (I assume they are talking about 97W) and this system.

On the other note, I observe thick cloud clusters in and out of the Philippine archipelago, associated with strong ITCZ activity (or the monsoon trough) and the strong surge of southwest monsoon. There are reports of strong rains in the metro and some areas in the country.

Yeah, I am not a expert, but checking all other sites, NOTHING!

But if PAGASA have got it right, along with the track, could be interesting. Has 2 Invests/TD/TS's ever merged before? Is it rare? Does it usually mean more intensity?

There was a programme on TV sometime ago that featured Hong Kong about 2 systems developing, turning into a Super Typhoon and what devastation it could do to a major city. I believe it was on Nat Geo

[KWT]

Yeah thats what I'm surprised about, the facyt they've gone a step further and actually called it a TS!

[KWT]

Oh it certainly can happen, Colin in the Atlantic developed through a merger of different invests.

[StormingB81]

What path do they have it on?

[Typhoon10]

What path do they have it on?

Westward, inbetween Taiwan and Philippines

[KWT]

I just don't understand what they are seeing...looking at the loops the region they've pinpointed for this mythical system is just about the least convective part in the entire region of the Pacific at the moment...

Oh and did I mention the large ULL thats a little to the NW of that supposed system.

[StormingB81]

I dont know i cant tell where its moving it looks huge but just a cluster..im confused for once..lol

[P.K.]

This makes no sense. As everyone in here can see there is nothing there so I have no idea what they are up to. Looking at a loop I'm not even sure what they are tracking.

The only thing that is close to that is....a nice big ULL...I sure hope they aren't trying to follow that feature, because that is just basic stuff really!

[oaba09]

Ok...I'm seriously confused LOL....We had some heavy rains earlier but it was mainly caused by the monsoon.....
