Weather forecast 16/03/2015

Race leader Cheminees Poujoulat has reached the northern edge of the trade winds, sailing to a ridge which extends roughly along 25N. They are now working their way upwind around the eastern periphery of the light wind zone under the ridge.

Neutrogena and GAES Centros Auditivos are crossing the doldrums and are working their way into the NE trade winds of the Northern Hemisphere. Neutrogena is sniffing those winds at the moment, but the trades have gotten lighter and more headed since the race leader went through.
We Are Water and One Planet, One Ocean & Pharmaton are quite far east, sailing north along 25W in search of consistent trade winds. This may be difficult for them over the next couple of days, as conditions look to be fairly light along their route.
Renault Captur is navigating on a more W’ly route to sail north in the Atlantic, but sailing in very changeable and unstable winds. Spirit of Hungary will likely reach Cape Horn today, chased there by a strong southern ocean storm approach quickly from the west.

*** SYNOPSIS ***
00Z MONDAY (16-MAR-2015)
1)    Deep low pressure (950mb) 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
Aires.
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
34N/39W.
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 34S/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 developing off Portugal.
00Z WEDNESDAY (18-MAR-2015)
1)    A strong W’ly from from Cape Horn north to the Falklands and east to
South Georgia Island. Weak high pressure (1018mb) near 44S/60W.
2)    A front southeast off the Argentinian coast, with another high (1021mb)
near 41S/47W.
3)    Sub-tropical low pressure (1013mb) near 37S/37W. Strong winds wrapping
into the low from the east and south.
4)    North of the low, a zone of very light winds between 33S and 25S,
where the trade winds return.
5)    East of 30W, the trade winds will hold, supporting flow into the
subtropical low to the south.
6)    Otherwise, solid trade widns north of 25S, veering from ENE at 25 S to
ESE at 10S.
7)    The doldrums will be between 02S and 01N – wider east of 30W and
narrower to the west.
8)    North of the Doldrums, the NE trade winds will be firming and filling
again as a sharp high pressure ridge move across the east Atlantic.
High pressure (1032mb) near the Azores and a low (1013mb) off the
Portuguese coast will support fresh to strong N’ly winds from Madeira
to the Canary Island.
9)    There will also be some surging of NE gradient between the Canary
Islands and Cape Verde Islands.
