Feel free to move to active storms, but TCWC Wellington/RSMC Fiji haven't picked up on this, and neither has NRL.

Moving ENE into more tropical areas.

It reminds me of the 95 Mediterranean hurricane. Looks pretty decent given where it is.

[StormspinnerD2]

The convection looks to have deepened in the last couple hours.

[StormspinnerD2]

Deepened a bit.

That looks quite amazingly like Vince did when it was a hurricane now, small region of deep convection around the eyewall with a nice eye present, very interesting little system!

It says "98P" in the sat page of the Pacific. http://www.ssd.noaa.gov/PS/TROP/mtsatfloat1.html

[Chacor]

Losing a bit of convection on the northern side now. Shear in the area is >40 kts.

[HURAKAN]

Convection returning to the northern part of the storm.

[Derek Ortt]

advisories should be issued. Not sure why they are not. It appears to be borderline tropical if anything

[HURAKAN]

07/1430 UTC 29.8S 164.7E ST3.0/3.0 98P -- South Pacific Ocean
07/0830 UTC 31.2S 163.8E ST3.0/3.0 98P -- South Pacific Ocean
07/0230 UTC 32.4S 162.4E ST3.0/3.0 98P -- South Pacific Ocean

Should we move this to the Active Storms forum?

[Chacor]

It's not an official NRL invest.

Derek I guess it's because they don't do subtropical advisories in this basin (TCWC Wellington). Maybe if it becomes more tropical and reaches 25S (enters Fiji's area).

[Derek Ortt]

even so, in the Atlantic this would likely have been classified as tropical (both north and south Atlantic). However, we do use a more liberal definition as to when TT has occurred

[HURAKAN]

Vince, this storm and the Mediterranean cyclones or hurricanes are very similar.

[Chacor]

Looking at the loop, appears to have taken a northern jog.

[HURAKAN]

Losing convection.
