YOTREPS

Compiled Sun 22 March 2020

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.

Voyaging in a COVIDI9 world:

Most countries have now implemented strict controls at ports of entry for visiting yachts in reaction to COVID-19 Coronavirus with many closing their borders and some enforcing a 14-day quarantine on arrival. The only places that are “open for yachts” in the South Pacific at present are American Samoa, Fiji, and Solomon Islands.

World Met Day 2020.

This year’s World Water Day and World Meteorological Day, on 22 and 23 March respectively, share the theme “Water and Climate Change”. They are being celebrated under extraordinary circumstances as The UN family comes together to tackle the coronavirus pandemic, with each institution playing its part.

One of the most effective ways to slow down transmission is to wash or sanitize our hands. However, globally three billion people do not have access to even basic hand washing facilities at home. Lack of access to clean water affects vulnerability to disease and ill health. It is especially acute among those living in extreme poverty in rural areas, as well as in informal urban settlements. Access to safe water is an essential component of the 2030 Agenda for Sustainable Development..

The 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

 

No cycones around at present.

The MJO is now weakening in the South Pacific, but keeps a potential area north of PNG. However this may be too close to the equator to form a cyclone.

 

WATHER ZONES

SPCZ=South Pacific Convergence zone.

The SPCZ is expected to stay much the same from Solomon Islands to north Vanuatu to Fiji.

Trough travelling across Fiji and Tonga between now and Tuesday.

 

Subtropical ridge (STR)

HIGH over Tasmania Tuesday night is expected to travel NE across the Tasman Sea this week and fade over northern NZ wed/Thu.

Another High is expected to cross Tasmania on Thursday night and reach southern NZ for the weekendby Friday local.

 

Tasman Sea /NZ/Aus

Trough crossing North Island on Monday followed by cool SW flow on Tuesday. Weak high for northern NZ on Wednesday then another trough o Thursday and cold southerly flow on Friday.

As for sailing east across the Tasman: it may be possible with a departure between tuday and Thursday, and again on Saturday.

As for New Caledonia to Australia: looks Ok this week, but for the border closures.

From Panama to Galapagos/Marquesas:

Borders are closed. If you are already out there then go to Marquesas via north of the Galapagos then to avoid the squalls of the “mirror” convergence zone, aim for 4;50 S 110W then go west to 125W then go direct.
