Instability should linger across our islands tonight with periods of light rain, scattered showers and isolated thunderstorm activity. Most of the shower activity is occurring just east of our islands and should generally decrease on Tuesday, but again low level shearline/trough could result in few scattered showers.
A High Pressure System should build across our area by Wednesday, with more noticeable drying out of the atmosphere on Thursday.
Light to gentle (5-20km/h) northeasterly breeze tonight should gradually increase to moderate (20-28km/h) by morning. Mean sea-level pressure is gradually rising to range 1014-1016mb by Wednesday as the High Pressure builds across our area. Models indicate reduction in visibility is possible across SVG ony Wednesday due to dust concentrations approaching the area.
Slight to moderate seas in open water should continue overnight, with northerly to north-westerly swells rising up to 2.5m especially at high tide times. These conditions expected particularly on the northern, north-western and western coastlines of SVG are expected to peak during Wednesday. The swells are a result of a deep-layered low pressure system in the northern Atlantic which continues to propagate large swells southwards to the eastern Caribbean. The HIGH-SURF ADVISORY and SMALL CRAFT WARNING already in effect, may be extended beyond 6pm Wednesday 7th March if necessary.
Please be reminded, that large waves and dangerous rip-currents can be expected mainly along the western, northern and north-east coasts of St Vincent and the Grenadines which will create unsafe conditions. Sea-bathers and other users of the sea are being advised to stay out of the water, especially in the areas identified during this period. see more in the advisory on home page http://www.meteo.gov.vc/meteo/
