The pressure gradient between Bermuda high pressure and the Colombian low will support nocturnal pulsing of minimal gale force winds off the coasts of Colombia and Venezuela through Sat night, except on Thu night. Strong winds are expected to pulse over the Gulf of Honduras each night through Sun night. A tropical wave near 65W will produce scattered thunderstorms with gusty winds as it moves W across the central and western Caribbean through Sat.
