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.

Wx Update, E Caribbean, Mon8, 10a
9p last eve ASCAT: Venezuela E of to SE
Caribbean ENE in area W of 64W / ESE area E of 64W (due to W-moving TROF near
64W), varying from 15-24k, strongest 63W-65W near TROF. W of area from StLucia-Martinique
ESE@10-15 / W of Dominica-Guadeloupe E@5-10 / W of Leewards and throughout
Virgins & PuertoRico SSE-S@5-13 (strongest PuertoRico's N Coast) / E DomRep
S-SW@0-10.
BUOYs:
60mi SW of Nevis: 160@6-10, 4'/5-15sec in combined seas from E & SSE & N.
21N/65W: 210@9-14, 6'/7-15sec in combined seas from SSW & N.
IMAGERY:
Isolated showers & mild qualls thru StLucia & StVincent along narrow band of
activity which stretches from beyond 16N/55W...Tortuga (11N/66W)...cells moving
W-WSW in the surface wind flow, while band continues shifting SE.
Scattered squalls from DomRep W of 70W thru extreme SE Bahamas...extends NE-ward
along FrontalTROF beyond 30N/55W...cells training NE along nearly-stationary
FrontalTROF.
SYNOPSIS:
SE Caribbean little change thru tomorrow, except stronger night-time wind...but
TROF approaches tomorrow night, with wind backing ENE & building to
20k...clocking ESE & moderating E of TROF Wed10 thru Thu11...mild E wind
thereafter, well S of RIDGE.
NE Caribbean light wind most of next 7-10 days, with ColdFRONTs along DomRep
today & Thu11 & Sun14 suppressing the weak RIDGE S-ward to near N Caribbean,
with periods of very light & possibly S wind those days...and only brief period
of E-component Trades tomorrow-Wed10 & Fri12 night-Sat13.
DomRep sees unsettled weather but mostly light wind with periods of squalls
possible...for E-bound vessels the good news is lack of much E-component wind.
Venezuela & ABCs: moderately-strong E-component wind, a bit higher ABCs, with
little day-to-day change.
ALL AREAS plagued by N-component swell throughout the period, but height,
direction & period will vary...increasing & decreasing every couple days. W
Venezuela & ABCs may not see much N swell.
F'cst:
Precip:
Trinidad area: mostly dry with only a little isolated mild activity with 5-10k
enhanced wind tomorrow night into Wed10, accompanying weak TROF.
Windwards & Leewards: even less activity.
VirginIslands & PuertoRico: mostly dry, unless FrontalTROF approaching region
Thu11 brings a bit of activity into area Thu11 night & Fri12.
DomRep: scattered showers & a few squalls with wind possibly to 25k should
spread throughout area later today & persist into Wed10 morning before
dissipating...then may return especially to W Part Thu11 with next FRONT. Best
guess is activity will not penetrate much into MonaPassage, with only isolated
activity possible thru tomorrow & again late Thu11-Fri12.
Venezuela & ABCs: similar to Trinidad, but any activity with TROF would be about
Wed10.
