This afternoon through Thursday midday: Northerly to Northeasterly with a gentle to fresh breeze of 11 to 20 mph and higher gusts up to a near gale particularly in and around showers.
The surface pressure gradient is forecast to tighten. The result of which will be increased wind speeds affecting the region from this afternoon lasting through the next several days. Additionally, remnant moisture associated with a dissipated frontal boundary, will be quickly pushed over the local area causing fast moving isolated showers during the forecast period.

A small craft advisory is now in effect for St Maarten. A warning will be issued as the worsening marine conditions and its expected onset draws nearer. Small craft operators and sea bathers should exercise extreme caution to guard against loss of life and/or property damage. Beach erosion will also be of concern, particularly along the eastern and northern shores of the Island.
