How to read: Forecast is for the Eastern Caribbean, with emphasis on the British Virgin
Islands. Wind forecast includes Virgin Islands, Leeward Islands (Anguilla to Dominica) and Windward Islands (Martinique to Grenada).
Wind direction and speed are given as a compass
direction, in degrees True (090 is East), "@" sign, followed by a number
designating the average sustained wind speed forecast. Forecast should be
"bracketed" by you...for example, a forecast for 090@16
means you should expect sustained winds between 080-100 at between 14-18 kts.

of ABCs. A few showers Windwards, moving NW. Mostly dry from W PuertoRico thru
DomRep.
SYNOPSIS:
--Areas SE of a line from Guadeloupe & Montserrat thru ABCs should remain mostly
dry indefinitely, with steadier E-SE winds which decrease some Thu11-Fri12 as
FrontalTROF makes another run to the S&E (maybe reintroducing a few showers to
SE Leewards Thu11 night & Fri12)...then E-SE Trades rebuild gradually as E
Atlantic RIDGE strengthens. Moderate N swell decreases gradually after
tomorrow.
--Most of Leewards & Virgins & PuertoRico remain very unsettled &
potentially-squally, with shifting winds of varying strength thru Thu11 or even
Fri12...but much more settled weather with mild E-SE Trades Sat13-Mon15, and no
significant N swell by then.
--Mona & DomRep build some from ENE-E thru Fri12, then decrease & clock toward S
over weekend, with L&V possible DomRep Sun14 & Mon15, as large, slow-moving LO
drifts in NW Atlantic.
--Venezuela & ABCs rebuild from E thru tomorrow...moderate some Thu11 afternoon
& Fri12...then rebuilds slightly.
