Tropical Disturbance Advisory Number A5 issued from RSMC NADI

Nov 22/2013 UTC 2006 UTC.

Tropical Cyclone YANI 04F [985hPa] centre was located near 12.9S

162.8E at 221800 UTC moving south-southeast about 03 knots but

expected to turn west. Position fair based on HRES MTSAT EIR imagery

with animation. Maximum 10-minute average winds estimated at 50 knots

increasing to 60 knots in the next 12 to 24 hours. Winds over 47

knots within 30 miles of centre and over 33 knots within 120 miles of

centre in the southeastern semicircle and within 90 miles of centre

in the northwest semicircle.

Organisation steadily increasing though appearing sheared. Primary

band still wrapping tightly around llcc. Outflow good to south and

west but restricted elsewhere. Dvorak based on curved band wrap of

0.85 on log10 spiral yielding DT=3.5, MET and PAT agree. Final T

based on DT thus T3.5/3.5/D1.5/24hrs. Cyclone is located just south

of a 250-hPa ridge axis in a divergent and weak shear region. SST

around 28-29C. Yani expected to move west under strong mid level

ridge to east and south. Global models generally agree on a westward

track with gradual intensification.

Tropical Disturbance Advisory Number A7 issued from RSMC NADI

Nov 23/0738 UTC 2006 UTC.

Tropical Cyclone YANI [CAT 3] 04F [965hPa] centre was located near

13.1S 163.0E at 230600 UTC. Position fair based on HRES MTSAT VIS/EIR

imagery with animation. Cyclone moving south about 04 knots but

expected to turn towards southwest in the next 12 to 24 hours.

Maximum 10-minute average winds estimated at 70 knots increasing to

80 knots in the next 12 to 24 hours. Winds over 63 knots within 30

miles of centre, and winds above 47 knots within 50 miles of centre,

and winds above 33 knots within 120 miles of centre in the

southeastern semicircle and within 90 miles of centre in the

northwestern semicircle.

Organisation steadily increasing. Ragged eye is again becoming cloud

filled on both EIR and VIS imageries. Outflow good to south and west

and fair elsewhere. Dvorak based on Eye Pattern yielding 5.0 with a

white eye with black surrounds. This yields a DT=5.0, MET=5.0 and

PAT=4.5. Final T based on PT thus T4.5/4.5/D1.0/24hrs. Cyclone lies

just south of a 250-hPa ridge axis in a divergent and weak-shear

region. SST around 28-29C. Yani currently steered south by a

mid-level ridge pushing from the east but is however expected to

eventually drift west under strong mid level ridge to south. Global

models generally agree on a southwestward track with gradual

intensification.

FORECAST:

12hrs valid 231800UTC near 14.0S 162.7E mov SSW at 05kt with 75kt

[Somerset Squall]

Another unusual storm!

[P.K.]

In what way is this unusual? This area should be active this season given the current ENSO conditions.

[Supercell Hunters]

LOL it dying now, now it usual haha!

Well I meant uncommon really, looking back the last time storms formed in this area in Oct/Nov was 2001. 2003 was the last year for a late year storm in this area, the action is usually towards the beginning of the year as far as I can tell.
