Prévisions météo du 4 février

Les quatre premiers bateaux de la flotte progressent dans des vents d'ouest solides. Les leaders bénéficient de vents modérés d'ouest après être passé près du fort coup de vent des ex-cyclones tropicaux descendus au sud devant eux.

Les conditions se compliquent pour les bateaux les plus à l'ouest. Des basses pressions au large de l'Afrique du Sud se déplaçant lentement vers le sud-est génère des conditions de près avec de forts vents de sud - est et une mer croisée pour One Planet One Ocean & Pharmaton et Spirit of Hungary.

48S/24E the east along 47S-50S to 45E. Within the ridge regions, winds
are lightest west of 24E, then light Síly flow extends to 45E. North
of this ridge, flow backs S to SE, extending up to 37S.
2) Low pressure (1003mb) near 35S/32E, moving southeast and deepening. A
trough will extend southeast of the low to 43S/37E to 47S/48E. South
of the trough S/SE winds while north of the trough mainly fresh N/NW
winds.
3) High pressure (1025mb) near 36S/61E. There will be a moderate to fresh
Wíly flow between the high center and the Ice Exclusion Zone,
strongest south of 42S.
4) An intense low (967mb) is centered near 50S/100E. There is a large
wind field associated with this storm. Storm force winds will extend
up to 200nm from the center, while gales will extend out to 400nm. SW
winds generally west from 100E to 84E. Winds veer NW/N east of 98E.

00Z THURSDAY (05-FEB-2015):
1) High pressure (1025mb) near 38S/05E with a ridge extending to 48S/30E
to 50S/45E to 47S/62E. North of the ridge axis, SSE/SE winds will
extend north to 38S to 38E. West/south of the ridge W/NW winds, but
these are generally out of range over the Ice Exclusion Zone.
2) Low pressure (1000mb) will move to 42S/44E with a trough extending to
45S/49E to 45S/60E. SE/S winds to the west and south of the low/trough,
shifting N to the east of the low north of 45S.
3) High pressure (1023mb) will move to 35S/73E with a large area of
mainly light and variable conditions extending from 60E to 90E and
between 32S and 37S. Mainly Wíly winds will be south of the high to
the northern edge of the exclusion zone , building fresh south of 40S.
4) The intense low (956mb) and combined remains of Diamondra and Eunice
will move to 62S/108E with a secondary low (963mb) west near 59N/86E.
A front will wrap out of the low to 51S/100E to 45S/95E to 40S/87E. NW
gale force winds ahead of the front and Wíly gales behind it.
5) A North-South ridge will be forming along 115E.

00Z FRIDAY (06-FEB-2015):
1) High pressure (1022mb) near 47S/34E.
2) Low pressure (1005mb) near 37S/32E. A fresh SE flow between the high
pressure to the south and low pressure to the north.
3) Low pressure (999mb) moves to 46S/65E. Strong Síly winds west of the
low and NW/N east of the low.
4) High pressure (1027mb) centered near 34N/87E, with a ridge extending
west along 33S to 65E and east of the high to southwest of Perth near
37S/115E.
5) Low pressure (generally 973mb) generally 61S/101E.
6) A broad flow of strong Wílies extends from 85E to 105E, south of 39S.
A cold front will wrap out of the low pressure to 51S/120E then
42S/110E to 39S/103E. The Wíly flow noted in (6) extends to this front.
Fresh to strong NW winds east of the front.

00Z SATURDAY (07-FEB-2015):
1) High pressure (1031mb) centered near 47S/49E.
2) Low pressure (1005mb) moves to 42S/32S. A fresh to strong NE flow
between the high pressure to the southeast and this low. Winds
strongest closer to the low northwest of 43S/38E.
3) A strong low (982mb) moves to 50S/89E, with a cold front extending
northwest to 45S/86E to 40S/77E. Strong (gale to possibly storm force)
NW wind east of the front, shifting gale force S/SW wind west of the
front.
4) High pressure (1026mb) centered near 34S/96E. A broad extension of the
high from 60E to 38S/110E. An extension of this ridge is south of
Cape Leeuwin into the Australian Bight. This keeps Wílies confined
mainly south of 40S.
