Bob McDavitt's ideas for sailing weather around the South pacific

22 January 2016

TC VICTOR starting it unwind as it dances around Nuku'alofa

The gales of VICTOR are tonight unwinding  as the cyclone slowly unravels  and dances around Nuku'alofa. 

 

VICTOR has been giving low pressures (below 1000hPa)  and strong and gusty winds to NIUE all week, with wind slowly swinging from a southerly to a northerly as VICTOR travelled slowly south.

 

NIUE weather data for past week  may be seen at Weather Underground at http://www.wunderground.com/history/airport/NFTF/2016/1/22/WeeklyHistory.html?req_city=Fuaamotu&req_statename=Tonga&reqdb.zip=00000&reqdb.magic=2&reqdb.wmo=91879&MR=1

 

Then VICTOR started to move to the southwest, getting closer to the equator-ward entrance region of the Jetstream—a  place favorable for further formation and surface pressure fall.

  However tonight VICTOR has gone too far to the southwest and is now encountering the increasing shear of the Jetstream, so will “have its top knocked off”.

 

 

Here is the latest text report about VICTOR from the Fiji Met Service at http://www.met.gov.fj/aifs_prods/20032.txt

 

TROPICAL DISTURBANCE ADVISORY NUMBER A36 ISSUED FROM RSMC NADI Jan 220746 UTC.

And this evening’s threat  map from Fiji Met Service may be seen at http://www.met.gov.fj/aifs_prods/65648.html

 

VICTOR has managed to dissipate a lot of energy from the ocean/atmosphere  as wind and rain (and swell , and mostly this has been done over the open sea,  and thus not been too been too damaging.
