The Western Atlantic High Pressure System continues to pump fresh to occasionally strong breeze across our islands. These brisk east north-easterly trades occasionally bring low level clouds with moisture across our islands with higher gusts near showers.
The building of the Western Atlantic High Pressure System should push instability (shearline/ low level trough) across our area Wednesday into Thursday. Thereafter, a weakening of the High Pressure could result in marginal reduction of wind speeds Friday. Also, cloudy skies with occasional shower activity could continue into Friday. The shearline is expected to dip southward with a mid level trough developing over the island chain Saturday, aided by upper level support. Mid level moisture should increase as the north-south oriented trough deepens across the island chain.
Fresh to strong breeze (29-49km/h) should generally decrease on Friday to moderate to fresh.
Moderate (1.5m to 2.5m) seas on the west and moderate to rough (2.0m to 3.0m) on the east are expected to continue tomorrow, increasing on the east with north north-easterly swells which may peak near 3.5m on Friday then retreat by Saturday. Clusters of Sargassum seaweed are also present along coastal waters.
Models indicate patches of dust concentration (20-80 ug/m**3) could reduce visibility in haze over the next few days.
