Dry air ahead and behind yesterday’s tropical wave depleted the chance for showers/thunderstorm activity. Visibility gradually reduced last night and moderate haze remained across our area today (20 - 80 µg/m3).
A weak low-mid level trough system should cross the region tonight with a few scattered showers. The next tropical waves are moving along with dry mid to upper levels, limiting cloud build-ups/shower activity. Occasional showers are anticipated on Thursday behind the wave axis.
The Atlantic High Pressure System should rebuild across the island chain by Friday, with low level cloud patches moving within the wind-flow bringing passing showers and alternating with dust concentrations of varying intensity.
Surface winds are expected to be moderate to occasionally fresh (20 - 40 km/h) overnight from the north north-east. A reduction in wind speeds should be noticeable by Wednesday afternoon before returning to fresh and veering south-easterly on Thursday. North-easterly trades associated with the Atlantic High Pressure can be expected by late Thursday.
Sea conditions are currently slight to moderate, with easterly swells ranging peaking near 1.5 m on the west coasts and up to 2.2 m on the east coasts.
Barometric readings should range 1013mb - 1015mb and occasionally top at 1017mb over the next few days
