Els líders aviat vorejaran la perifèria occidental de l'alta pressió de l'Atlàntic Sud (l'anticicló de Santa Helena) amb l'objectiu de fer front a un intens vent prefrontal del NW acostant-se als 30ºS. Mentrestant, els vents alisis ESE / E seguiran sent d'ajuda per a la meitat de la flota en el seu camí cap al sud. S'espera que Spirit of Hungary per creuar aviat les calmes equatorials i entrar en els vents alisis de l'hemisferi sud.

*** SYNOPSIS ***
00Z FRIDAY (16-JAN-2015):
1)    The doldrums are active with showers and thunderstorms, but narrower 
this morning as they shift south from 2N toward the Equator.
2)    South of the doldrums, winds are generally ESE all the way south to 
23S. Winds will back more ENE/NE west 35W and south of 20S. 
3)    High pressure (1022mb) is near 27S/25W, elongating west to east 
between 25S/36W and 28S/15W. West of the high pressure, winds back NE 
to N to set up pre-frontal gradient ahead of a cold front. 
4)    Deep low pressure (960mb) is near 48S/20W. An associated cold front 
extends north of the low to 38S, then west-northwest to 32S/33W before 
becoming stationary and extending to the coast near Florianopolis.
5)    Winds between the front and southern side of the high pressure will be 
mainly moderate NW between 26S and 31S.
6)    The front will be stationary or shifting south with time.
7)    A second high (1022mb) near 38S/47W. This high will be moving quickly 
east just to the south of the stationary front.
00Z SATURDAY (17-JAN-2015): 
1)    Little change in the SE/ESE trade winds from the Doldrums, south. 
There will be lighter E’ly winds now over the waters south of the 
doldrums to about 3S. The ESE/SE trades will be well established south 
of 5S to 22S, but the wind field will be a little unstable, with 
embedded clouds and showers.
2)    A persistent area of stronger, more consistent wind will be in a zone 
around 9S to 13S/32W to 25W.
3)    South of 18S, winds will be backing NE/NNE between 30W and the 
Brazilian coast.
4)    High pressure (1022mb) will be centered near 28S/26W. A ridge will 
extend west of the high to near 25S/35W. This ridge axis marks the 
shift from E/NE trades to the north, to N/NW pre-frontal winds to the 
south around the southwest quadrant of high pressure.
5)    A zone of accelerated NE flow will persist south and east of Cabo Frio.
6)    A stationary front will lie west to east along 31S. A second high 
(1022mb) moves to 35S/20W. Over the course of the day, the front 
between the two high pressures washes out, and the high merge and move 
southeast.
00Z SUNDAY (18-JAN-2015):
1)    Steady, moderate E/ESE winds north of 16S.
2)    Lighter  and more patchy trade winds south of 15S and east of 35W 
where the South Atlantic high becomes a ridge extending from 22S/32W 
to 30S/18W to a high center (1027mb) near 37S/4W.
3)    A cold front will move north of 38S at 30W and near 35S at 35W. Strong 
N winds off Cabo Frio back to strong NW’lies ahead of the front and 
south of the high pressure ridge.
00Z MONDAY (19-JAN-2015):
1)    Moderate E’ly trade winds will extend from about 10S to 20S.
2)    Trades weaken and back E/ENE north of a ridge axis from 30S/20W to 
27S/30W to 25S/35W. Between the ridge and Cabo Frio, winds accelerate 
NE/NNE.
3)    A cold front stalls around 33S at 30W. This will also mark a col 
region of light and variable winds. 
4)    The W’lies will be active south of this col along 37S at 30W.
