REMARKS:
Embedded centre pattern with Black surround, giving a DT of 5.0. MT and PT both
suggest 4.5. FT based on PT and supporting ship observations.
Severe Tropical Cyclone Zelia has rapidly intensified during Saturday evening
while in a favourable environment with weak wind shear and high sea surface
temperatures. Recent IR satellite imagery has indicated that a ragged eye
pattern may be developing.

Re: SPAC: ZELIA (10U/07P) - Tropical Cyclone
Core at 2C. PV just about at the surface.
Moving into a very strong anti-cyclone.
Strong cell just about ontop of the COC.
IMHO, could RI if a hot tower fires off.

100kts almost certainly looks like a good call right now!
Its a very tight system with a small core and the Sat.estimates if anything maybe a little on the low side.

Re: SPAC: ZELIA (10U/07P) - Tropical Cyclone
No doubt it is a major now, I hope that the agencies take into account that Dvorak may be conservative given its small size as you said.

Re: SPAC: ZELIA (10U/07P) - Tropical Cyclone
This got upgraded a while ago, can someone update the thread title please?
For comparison I've just looked at all the latest Dvorak bulletins. These suggest probably now a bit stronger than it was in the 18Z advisory. I'd suggest we are looking at 90kts now compared with 80kts in the 18Z advisory. Won't be long until the 00Z advisory and they may well upgrade to a cat 4.
BoM at 18Z - T5.0/5.0/D2.0/24HRS
SAB at 2030Z - T5.5/5.5/D2.0/24HRS
CIMSS ADT at 2230Z - T4.3
Can anyone find the JTWC bulletins? The usual archives don't seem to be picking them up.
