Summary:
1) satellite shows one low
pressure area that is spiraling to the S of the
Chatham Islands, slowly
moving off to the E
a) which will allow the complex surface and upper level low
pressure areas
that are approaching NZ from
the W to continue to slide off to the E
b) in addition, a "tropical" low is still forecast to be
pulled S from the
Fiji area to be wrapped into
the approaching low/cold front centered near
39S/170E by 12utc on the 8th
c) if the position of this low and the cold front (stretching N along
170E) verifies on the 8th,
your winds will still be out of the NW and a
little more stable than once
the cold front passes and you get into the
blustery and cooler W-SW
winds
2) latest timing shows the
W-SW winds to move in between 18utc on the
8thand 00utc on the 9
th
a) expect about 24-36hours of gusts winds and higher seas through
00utc on
the 10th
b) then easing conditions as you continue N and the low continues
E
3) once conditions improve,
you should be able to head on a rhumbline toward
Savusavu, probably on the
11th
Routing:
1) recommend continued
routing toward the N until the 11th
a) can then head on a NNE course toward Savusavu as winds and seas
ease
