Butlletí del 12/04/2015
El Renault Captur ja està a l'estret de Gibraltar amb un flux de vent de l'Est. Jörg Riechers i Sébastien Audigane navegaran de cenyida en la seva remuntada del mar d'Alborán tot i que les condicions seran moderades al llarg de la cota espanyola. Per la seva banda, l'Spirit of Hungary ha baixat el ritme alhora que rolava el vent de la carena de la subtropical cap al Sud davant d'un front fred que està rotant al voltant d'una baixa pressió al nord-est de les Açores. Aquest front es mourà cap al Sud, fins als 30ºN avui, rolant el vent cap al nord permetent a Nandor Fa i Conrad Colman fer una ruta més directa cap a Gibraltar.
*** SYNOPSIS ***00Z SUNDAY (12-APR-2015)1) High pressure (1023mb) of the coast of Galicia Spain maintains a ridge south-southwest to just northwest of Madeira. A low pressure (1007mb) near 45N/21W with a cold front extending south-southwest to 33N/30W. The front moves south to 30N west of 17W through the day.2) NE trades south of 30N will back N with time weaken. NE winds along the Portuguese coast to Madeira and Canary Islands ease and back N with time. 3) Moderate to fresh E’ly through the Gibraltar Strait.4) High pressure over central Europe will support NE/E winds off the south and east coasts of Spain. Winds will be stronger offshore and from the Balearic Islands to the Algerian coast.5) Closer to the Spanish shore, overnight drainage winds will generally lead to lighter breeze of local N/NW winds. Daytime sea breezes will be present, but generally light under the influence of unfavorable NE gradient. 00Z MONDAY (13-APR-2015)1) A col region with light and variable winds just southeast of Madeira. A weak ridge will extend from the northwestern Canary Islands west along about 27N.2) Low pressure (1016mb) near 36N/19W with a front extending south to 20N/20W then west-southwest to 28N/27W. A push of N’ly breeze moves south in the wake of the front, veering NW across the Canaries and around the southern periphery of the low pressure.3) Light and variable winds along the Moroccan coast, with daytime sea breezes. A fresh E’ly flow out of the Gibraltar Strait and across the northern Gulf of Cadiz.4) High pressure over northwestern and south-central Europe drives a fresh NE/E flow south of Spain. Lighter conditions along the east coast and across the Balearic Sea. Sea breezes will be widespread along the coast in the afternoon.00Z TUESDAY (14-APR-2015)1) Low pressure (1016mb) northeast of Madeira near 35N/14W. A cold front extends from the low south to Lanzarote southwest to 24N/23W to 24N/35W. Winds N’ly west of the low, backing NW across Madeira to 30N and the waters west of the Canary Islands.2) East of the cold front and low, mainly light winds from along the Moroccan coast north to about 35N in the Gulf of Cadiz. At and north of 25N, winds E’ly and generally moderate in strength.3) Fresh to strong E’ly flow through Gibraltar Strait. 4) High pressure over the western Med will support a fresh to strong NE/E flow from Palma to south of Almeria. Backed gradient flow (NE) may result in lighter winds off Gibraltar to Almeria. Lighter winds along the Spanish coast, with a good chance of afternoon sea breezes.5) Light NE winds Gulf of Valencia. Off Barcelona, winds will be light and variable, with local sea breezes dominant there.**************************************General Forecast along race route*** SUNDAY (12-APR-2015) **** 27N to 32N and 28W to 18W *WIND: North of 30N, W 10-15 tending N 15-20 gusting 25.
