Re: WPAC: TS Kalmaegi (JTWC: TD 08W, PAGASA: TS Helen)

Well Shanghai is certainly with the cone of uncertainty at the moment so I though I'd post a comparison of what the regional agencies are forecasting at the moment. As Chacor just said JMA have now upped Kalmaegi (from now on KM since it's hard to type) to 40kts.

JMA, HKO, CWB and Pagasa are all going for a similar track at the moment. JTWC have swung more poleward in their latest warning #6 but are still the most westerly of all forecasts at the moment.

Here's the 12z JMA track which suggest Zhejiang/Shanghai area could be at risk:
Image

And here's the 09z track from HKO, similar to what JMA are forecasting:
Image

And a similar scene from CWB at 12z:
Image

And Pagasa who originally were predicting a westerly track have swung to the north in their 09z update:
Image

And finally the most western track of them all the 12z from JTWC, it still blobs a tropical depression over me at the weekend!
Image

It's certainly shaping up to be a very interesting week tracking Kalmaegi.
Mods if I've posted too many pics or they're too large for the forum please let me know and I'll zap them. Cheers.

Looking decent right now, I was wondering when the WPAC would pump out its next system. Anyway its got nice deep convection as evidenced by the IR images in this thread, I see no reason why this won't strengthen unless it gets too close to land.

Hmmm 3.5, thats pretty impressive that supports a pretty strong tropical storm. I thinkits strength at least in the next 24hrs will be totally dictated by how close it gets to land in that time period.

Looks like its close now to being upgraded, very impressive looking system. Really large are aof deep convection with this system right now, probably will strengthen pretty rapidly now.

Not common for JTWC to have it as a TD when JMA already have it as a storm.

The Last Kalmaegi was a TD by the JTWC!! But that was yesterday.

Hi Ed.

I won't be flying to Taiwan for this since I'm in Shanghai at the moment and it could be passing very close to the city. I think JMA are doing hourly updates now.
