Weather Forecast 15/03/2015

Cheminees Poujoulat course has turned more northerly now as the trade winds have veered while sail further to the north. They will begin entering into lighter winds across a high pressure ridge today.

Neutrogena has reached the doldrums and slowed accordingly while GAES Centros Auditivos gained ground from behind with stronger SE trades. However they too are entering the doldrums and will be slowed before reaching the NE trades north of the Equator.

We Are Water and One Planet will soon have some tricky, fast-changing winds to cross, as they approach a stationary front lying west to east across their path. North of that, a large area of lighter winds has developed, but should start to fill in before they arrive.

A cold front has passed Renault Captur putting them in fresh S winds, but a high pressure will approach quickly from the west today.

Spirit of Hungary continues to make quicker progress toward Cape Horn, sailing in strong, squally Wílies.

*** SYNOPSIS ***
00Z Sunday (15-MAR-2015)
1)    Low pressure (973mb) at 54S/96W. A trough axis extends north along 95W
with NW winds east of the trough to near Cape Horn.
2)    More low pressure southeast of Cape Horn. There will be strong W’lies
from Cape Horn to south of the Falkland Islands.
3)    High pressure (1020mb) will be moving southeast off the Argentinian
coast behind a cold front that will extend from 53S/32W to 44S/38W to
4)    High pressure (1029mb) near 45S/16W with a ridge extending northwest
to 34S/46W. NW/N winds between the cold front and ridge. North of the
ridge, E’ly winds extend to 30S, where a stationary front will lie
west to east.
5)    A zone of light and variable winds under a broad high pressure between
30S and about 18S. This will be a slow and tricky section for any boat
trying to get north to the trade winds (which will be confined north
of 18S>
6)    Moderate E/SE trades from 18S to the doldrums around the Equator. At
the moment, it looks like the doldrums transition will be fairly easy.
7)    The NE trade will still be moderate between the northern doldrums
boundary and abut 25N. However, there will be a trend toward easing
winds in the northern Hemisphere trade wind region.
00Z MONDAY (16-MAR-2015)
1)    Deep low pressure (948mb) at 60S/83W with a front wrapping out of the
low to Cape Horn then northwest to 40S/87W.
2)    Broad NW flow off the southern Argentinian coast and across the
Falkland Islands.
3)    High pressure (1024mb) near 45S/35 with a ridge extending east along
45S to 50W. This high is moving east.
4)    A stationary front north of the high from 43S/27W to 39S?41W to Buenos
5)    A weak trough zone lies across 24S, with a wide band of light winds
approximately 1-2 deg latitude either side of the tough.
6)    E’ly trade winds start north of 21S, tending E to SE north of 13S.
7)    The southern Doldrums boundary around 02S, with the northern boundary
near the Equator. NE trade will be moderate in the north Atlantic
between 05N and 30N, with the Atlantic high (1029mb) located near
00Z TUESDAY (17-MAR-2015)
1)    Low pressure south of Cape Horn with a strong W’ly flow across the
Cape and NW winds west of the Cape.
2)    A front will extend 60S/54W to the Falkland Islands to 42S/65W. East
of the front, Fresh to Gale Force N/NW winds from Mar del Plata to
South Georgia Island.
3)    High pressure (1030mb) with a ridge extending west-northwest to BA.
North of the high and ridge, a moderate E’ly flow south of 35S.
4)    Low pressure (1011mb) near 33S/36W, with fresh N/NE winds to the east
of the low across to 25W and stronger NE/E winds south of the low.
5)    Consistent trade winds will shift north of 18S at 30W. The trades will
increase and slowly veer with distance north.
6)    The southern doldrums boundary is forecast to move south to near 03S.
The northern limit will be around 01S, but NE trades to the north will
be lighter than they have been up to about 05N. North of 05N, NE
trades will be moderate and near normal strength.
7)    High pressure (1029mb) will be centered just to the west of the Azores,
with NE winds extending from 30N, across the Canary Islands to the
Cape Verde Islands. Winds will veer to distance west – NNE/NE at the
Canary Islands to ENE at 30W.
8)    A strong low will be move off Portugal.
