Weather maps by email

Now that MetService is decommissioning ZKLF at the end of June, sailors
without access to satellite phones are asking me if there is any way that
they can get weather maps.

The answer is YES, thanks to the gratis work done by Alex and Max of the
Yacht Y2K.
I think they are now in Fiji, see y2ksblog.com. When they were stuck in
French Polynesia during Covid, Max in his spare time produced the following
web page:y2ksail.com

By delving into the inners of the websites at Fiji Met Service and NZ
MetService he has added to the library of weather products available by
saildocs.

Remember, all you need to get email via SSB is a pactor modem and a laptop
with software and a sub from www.sailmail.com
To request a webpage via saildocs tune into the nearest sailmail transmitter
and use their software to send an email, no subject required to
query@saildocs.com with the message:

SEND webpage (Where webpage is https:// whatever.whatever as listed below)

Note that in this blog I have replaced the https:// with a *
to stop wordpress playing with it.

The full list of weather products produced by Y2K are listed at y2ksail.com

They include the following.

TROPICS
Cyclone MAWAR knocked out power in Guam and they are still in recovery mode.
It is about to sideswipe Taiwan.
The MJO, a burst of extra energy in the tropics, is now moving out of the
Pacific.

WEATHER ZONES
South Pacific Convergence zone SPCZ
The South Pacific Convergence zone is expected to do some rebuilding over
the Coral Sea to Fiji area this week. A trough might form south of Fiji on
Mon/Tue.

HIGHS and LOWS
High H1 to east of NZ is moving off top the southeast.
Low L1 in central Tasman is moving off to the south. Its associated front
has a NE gale over northern NZ tonight due to a squash between H1 and L1.
Low L2 is expected to form south of Gambier on Monday and deepen as it goes
SE.
HIGH H2 is expected to travel steadily across the North Tasman this week and
fade near Northland around Friday.
Late in the week L3 should cross the South Tasman Sea onto NZ, followed by
H3
The gulf of Panama = Light winds or SW winds this week=not much good for
Panama to Marquesas.
