THE ROLEX SYDNEY HOBART YACHT RACE 2021
There is expected to be a southerly for the start of this years Boxing Day
start to eh Sydney to Hobart yacht race. At this stage the GFS model is
making more of this southerly than the EC model

TROPICS
Tropical cyclone RAI brought a death toll of 76 or more to Philippines last
week and is now recurving in the China Sea and heading towards Taiwan.

There is a strong chance that a new tropical system may develop over Vanuatu
by the end if this week and then could perhaps head for Fiji or south of
Fiji during Christmas or soon after.

WEATHER ZONES
SPCZ=South Pacific Convergence zone.

HIGHS and LOWS
LOW L1 is forming in a trough west of Fiji and is expected to go towards the
northeast of NZ by mid-week and then off to the southeast.

HIGH H1 over northern NZ tonight is travelling east along 35S this week,
allowing L1 to come south in its wake.

LOW L2 is forming in a convergence zone over Southern Cooks around mid-week
and then travelling southwest and south into the zone left behind by the
remains of L1.

LOW L3 is expected to form over northern Vanuatu by the end of the week,

And next weekend there may be a tropical low forming over northern
Queensland.
