Weather Forecast 24/03/2015

Cheminees Poujoulat did a bit better than expected with respect to progress yesterday. However they are sailing in lighter breeze and will have slower progress today as they sail into a transition zone between W/SW breeze over the Alboran Sea and a developing N/NE wind over the northwestern Med and along the East coast of Spain. Neutrogena and GAES Centros Auditivos are sailing upwind angles toward the Canary Islands. The winds have been moderate, but expected to increase and back more NNE, hopefully allowing them to sail in clearer air north of the islands. We Are Water and One Planet, One Ocean & Pharmaton have finally escaped the doldrums. One Planet, One Ocean & Pharmaton was first out in their more easterly position, and is now in building NNE trade winds. Renault Captur is continuing to sail up the Brazil coast in relatively light winds. The South Atlantic trade winds are forecast to improve with time and as they get further north off the coast. Spirit of Hungary is reaching NE through some SE'ly trades, but these may diminish somewhat as they reach a transition zone along 28ºS.

*** SYNOPSIS ***

00Z TUESDAY (24-MAR-2015)
1) Low (1009mb) near 52S/38W. Front extends from the low to 48S/45W to
41S/62W. Low (1018mb) near 44S/31W.
2) High pressure (1023mb) at 35S/43W with a ridge extending to 42S/26W.
3) Low (1015mb) near 25S/36W, supporting N/NE winds down the southeast
coast of Brazil from Cabo Frio to 16S.
4) Trades veering E north of 16S, and extend north to the southern
doldrums boundary at 05S.
5) A wide doldrums with light and variable wind to the northern boundary
near 01S.
6) North of the Equator, moderate to fresh NNE wind, veering NE by 10N.
7) High pressure (1034mb) 47N/23W with a ridge extending to 37N/32W.
Strong Níly winds east of high backing NW as they flow into the Gulf
of Cadiz.
8) Low (1001mb) over southern Spain, This will support strengthening
winds through Gibraltar Strait.

00Z WEDNESDAY (25-MAR-2015)
1) A high pressure ridge lying along 38S from 46W to 23W. Meanwhile, low
pressure (1012mb) near 28S/28W. A front extends from the low to
23S/32W to the Brazilian coast near 19S/38W. South of the front there
is a Síly flow to 30W, where it backs to SEíly north of the high
pressure ridge and south of the front.
2) A high pressure ridge lies along 18S from the Brazilian coast east to
29W. A patch of light winds around the ridge. The south Atlantic trade
winds north of the ridge are moderate from the ESE to the southern
doldrums boundary near 05S.
3) The doldrums continue to be quite wide, with more or less light and
variable winds between 05S and the Equator. There is a light Wíly
return flow within the doldrums east of 30W between 03S and 01S.
4) North of the Equator, NNE trade winds moderate and in place to 10N.
From 10N to 30N, trades veer NE, except hold fresh and NNEíly along
the African coast.
5) High pressure (1032mb) near the Azores with a ridge extending
southwest. Broad low pressure 1000mb is over the Mediterranean Sea
from Palma to Sicily. Fresh to strong Nílies over the Atlantic north
of 30N from 18W to the outer Gulf of Cadiz.
6) Nílies ease across the Gulf of Cadiz, but back to flow from the W
through Gibraltar Strait. A moderate Wíly of the Alboran Sea to the
southwestern Med.
7) Fresh NW/N winds along the Spanish coast west of low pressure, with a
developing Mistral out of the Gulf of Lyon toward Palma.

00Z THURSDAY (26-MAR-2015)
1) High pressure (1022mb) near 36S/35W with a ridge extending northwest
to near Rio. West of the ridge axis mainly light to moderate Níly
winds. East of the Ridge axis SE winds. Winds back SE to E to NE to N
across the ridge axis.
2) Southeast winds extending north to 18S. A weak ridge across 17S with
light winds from 18S to 15S. North of 15S, the trade winds will be
present but relatively lgith from the E/SE. Trade will be stronger
west of 30W and lighter SEíly east of 30W.
3) The southern doldrums boundary will be near 4S. Light and variable
winds in the doldrums to about 01S or perhaps even to the Equator.
4) North of the Equator, moderate NNE winds building with distance north
and veering NE around 12N.
5) Moderate NE/ENE trades from 13N to 27N, veering with distance north
and stronger (fresh) east of about 26W.
6) High pressure (1029mb) near 37N/21W. This hich will support strong
Nílies east of 12W, spread south down to the Canary Islands.
7) Over the Med, low pressure (999mb) over Tunisia and Sardinia (1003mb).
There will be a Mistral developing out of the Gulf of Lyon with strong
winds extending from there south to waters east of Palma. Along the
Spanish coast, local areas of stronger N/NW winds are likely,
especially out of favored valleys in a NW gradient.
