Bob Blog 25 July 2021

Bob McDavitt's ideas for sailing around the South Pacific.

Compiled Sunday 25 July 2021

Regarding last week's blog, with its checklist for handling a squall, it has
been suggested that the mnemonic for remembering it be replaced with the
word PRICK (rather than APRICOT), dropping the A (Anticipate) and O (Over),
and replacing the T for Thunder with K. Rather rude but more memorable.

Also, this week I would like to share with you a link to a COMPRENDIUM OF
WEATHER INFORMATION FOR FRENCH POLYNESIA
(svsoggypaws.com/files/French%20Polynesia%20Weather%20Compendium.pdf) as
prepared by David Vogel and available with a host of other information at
svsoggypaws.com/files/. This is a must read for yachts visiting French
Polynesia and useful for those planning to get from there westwards across
the South Pacific.

TROPICS
The latest cyclone activity report is at tropic.ssec.wisc.edu and Tropical
Cyclone Potential is from www.ssd.noaa.gov/PS/TROP/TCFP/index.html

In-Fa is making landfall onto China. Cyclone NEPARTAK is heading towards
Japan, and expected to weaken (a little) on Tuesday. So, the outlook is for
wet and windy conditions mid-week for the Tokyo Olympics.

WEATHER ZONES
SPCZ=South Pacific Convergence zone.
The SPCZ is expected to be about average stretching from Solomon Islands to
Fiji/Tonga, and a convergence zone s expected near Samoa occasionally over
Southern Cooks and Tahiti area.

HIGHS and LOWS
1 Active trough is crossing NZ tonight and on Monday followed by squally
west to southwest flow until Tuesday. Avoid.
2 LOW traveling east along 30S south of Southern Cooks early this week
bringing light winds to French Polynesia FP.
3 HIGH 1020+in Northern Tasman Sea by Tuesday expected to travel east along
30S and reach south of FP by end of the week. Good trade winds with this
High.
4 Active trough in Tasman Sea by Thursday. LOW 995 expected to form in this
trough over northern NZ on local Friday and then travel east along 30S until
early next week bringing westerly winds as far north as Samoa. Good for
getting east but wait until early Aug if going west from FP.
