World ARC Weather - Leg 3
| World ARC Weather - Leg 3 |
Issued 19th February 2010 |
SHORT RANGE SYNOPSIS VALID 02/19/1200 GMT to 02/21/1200 GMT - The fleet continues to enjoy a mainly steady, albeit light, gradient wind from La Libertad to Galapagos. The pressure gradient between S Pacific high pressure and equatorial low pressure continues to drive winds in this region between 01N-04S. Generally expect 08-12 kts with occasional lulls. Winds remain highest to the south and lowest to the north. Expect a gradual backing of the flow from the S off the coast of Ecuador to SE/ESE near the Galapagos.
High pressure over the Gulf of Mexico & the semi-permanent Colombian low have caused fresh to strong winds for those sailing from Panama in much of the Gulf of Panama to about 03N east of 83W. These NNE/NE winds likely ease
from 18-25 kts to 15-20 kts in 24-36 hrs. Variable and much lighter winds under 10 kts between 01N-03N east of 85W associated with ITCZ that extends from 04N/78W to 06N/92W. Light 05-10 kt winds trending from the SE to SW
between 05N-01N from 85W-92W.
