Bob McDavitt's ideas for sailing around the South Pacific.
Disclaimer: Weather is a mix of pattern and chaos; these ideas are from the
patterned world.
Compiled Sunday 14 November 2021

NZ immigration has reduced the required managed hotel isolation Q time from
14 days to 7 days for those flying in , and to 10 days for yachts with
time-spent-at-sea counting, so this will help those sailing into NZ from
overseas.
Tomorrow the South Indian Cyclone season nominally starts and lasts until 30
April 2022.
Last Wednesday the equatorial westerly winds in the Indian Ocean helped
produce a twinning of lows near 10degrees north and 10 degrees south

The Flooding of Australia
It has only taken a week and one muggy and windy low to bring wind and rain
affecting half of Australia as reported here

r-second-day-of-heavy-rain-with-potential-of-more-flooding-and-hail/e61b0587
-f468-4334-b820-710b8645dec1
the Low broke many rainfall records, even Alice Springs got over 100mm in a
day, Perth got a double monthly average rainfall in one day and top weekly
accumulation was 440mm at Samuel Hill in coastal Queensland,

TROPICS
We are having the typical mid -November hiatus with no cyclones around at
present.

WEATHER ZONES
SPCZ=South Pacific Convergence zone.
The SPCZ is stretching from PNG across Solomon Islands and northern Vanuatu
to Samoa.
A convergence zone over French Polynesia is expected to fade by mid-week.
A low, L3, is likely to form between New Caledonia and Fiji by Saturday and
then travel southeast to be east of the North Island by Monday 22 Nov.
Looks Ok to sail to NZ from the tropics this week or next week, but avoid
L3.

HIGHS and LOWS
HIGH H1 between Fiji and NZ is moving east along 32S.
LOW L1 980 in south Tasman Sea-the one that flooded much of Australia - is
travelling ESE across the south of NZ, making a zone of strong westerly
winds over NZ until Tuesday turning SW on Wednesday and Thursday.
HIGH H2 is expected to form east of New South Wales on Wednesday and then
travel east across the North Island on Friday.
LOW L2 is expected to be in the Australia Bite by mid-week, cross Tasmania
on Thursday and turn into a trough reaching the Tasman Sea to South Island
by Saturday.
