Tropical Storm NARI (0711) in WPAC

[CrazyC83]

Nari has gone from a CI of T3.0 to T4.0 in just six hours so a STS now no doubt in the update in 30 min.

T4.0 supports a typhoon in terms of 1-min sustained winds...

Well, if you look close enough you can certainly figure out an eye-like feature.

[CherlynV]

Well, you would not know we have yet another tropical system on our doorstep by stepping outside -winds are 12 knots, with some patches of sky amongst the mid- and high-level BKN decks.

Will be interesting to see how this one pans out for us.

Wow, this thing rapidly intensified too! Took directions from Humberto perhaps???

[HURAKAN]

WOW:

[RL3AO]

TD to TY from the JMA in 24 hours.

[WindRunner]

JTWC is going to have a lot of catching up to do the next couple of hours . . . if it was 65kts before, it is definately more than that by now!

[CrazyC83]

TD to TY from the JMA in 24 hours.

That is almost the exact same rate as Humberto, considering that this is 10-minute sustained here...

[Matt-hurricanewatcher]

TD to TY from the JMA in 24 hours.

Slightly slower by about 6-8 hours from Humberto the record holder for depression to hurricane.

I'm sure in the WPAC there have been cases of faster intensification than Humberto...

[CrazyC83]

How fast did Nari go from TD to Typhoon according to the JTWC? I think we have a good comparison study here: Humberto vs. Nari...

[RL3AO]

JTWC advisories (every 6 hours)

1: TD
2: TD
3: TS
4: TS
5: TY

18 hours from TD to typhoon there too...

[Chacor]

Not really comparable, seeing how JTWC don't do intermediate and special advisories.

[HURAKAN]

FOR THE JTWC:
WAKE UP PEOPLE!!!
65 KNTS???

[Chacor]

JMA just went nuts on this. Up to 75 kt.

Has to be at least a solid Cat 2 in terms of 1-min winds.
