Lisa Blair establishes NEW sailing records
Lisa Blair is a solo adventurer sailor from Sydney and skipper of
CLIMATE ACTION NOW or CAN

She combines measurements of oceanid pollution with the sport of
establishing sailing records, to promote awareness of the message that
we need to make changes for the sake of the health of the ocean.

On 25 May 2022 she became the fastest person to sail solo non-stop and
unassisted around Antarctica, slicing 10 days off the original record

She added this record to her 'Around Australia' record (58 days)
established on 17 Dec 2018.

This year she added the 'Across the ditch' Sydney to Auckland World
record to her portfolio (to be ratified by WSSRC) in 8 days 3 hours
and 19 minutes slicing more than 4 days off the record

On 6 April She was greeted at the finish line with a hooting welcome
escort by hosts RNZYS to Westhaven Marina.

Then on 24 May 2024 she added the "Around New Zealand" record to her
portfolio , doing a solo non-stop unassisted navigation over NZ in
just under 17 days.

The record, to be adjudicated by the RNZYS in collaboration (CYCA) and
WSSRC, required her course to enclose the whole of New Zealand
including all rocks and islands lying within 8nm of the mainland.

"I'm sailing to save our oceans and to show people that as individuals
we all have the power to create change, it just starts with one
action.". Lisa Blair.


MetBob is a proud sponsor for CAN and I have been offering virtual
weather guidance to Lisa during her adventures.

CAN arrived back in Sydney on Saturday 15 June and is planning to sail
around the Arctic ocean next.

TROPICS
There is now a risk of cyclone formation off Mexico next few days.

WEATHER ZONES
The South Pacific Convergence zone is a narrow zone mainly along 10 to
12S from Solomon Island eastwards to Tokelau, with no signs of
development this week

There are passing troughs in the tropics - as extension from the
mid-latitudes, with one passing Tonga on local Monday/Tuesday and
another around Sun/Mon 23/24 June. The first passing trough is
expected to travel east and reach Tahiti on local Fri/Sat 21/22 June.

HIGHS and LOWS

HIGH H1 is travelling ENE along 35 to 25S to be south of Tahiti
mid-week.

Low L1 is moving across central MZ tonight with squalls on its
northern side and travelling quickly southeast. It is followed by a
gap between systems - with light winds.

By mid-week a new low L2 is expected to form near 30S 180 (comes from
a leapfrog aloft. This Low is expected to travel SE and deepen quickly
and should bring some SW winds onto Tonga area. A HIGH H3 is expected
to travel from Southern Ocean to Chathams. This makes a squash zone
between L2 and H2 with strong easterly winds onto eastern North
Island.

Low L3 remains inside the Tasman Sea all week, rotating around and
remaining intense thanks to a closed upper Low. It is a breeding
ground of squall zones, one of these reaching NZ around Friday. The
Low itself may reach NZ early next week. this depends on a new High H3
which this week is stuck over Australia.
