HAZARDS AFFECTING LAND ---------------------- WIND: Gusts to tropical storm force in squalls are still possible across the Windward Islands overnight. RAINFALL: The remnants of Don are expected to produce total rain accumulations of 3 to 6 inches, with isolated higher amounts, across Trinidad and Tobago, the southern Windward Islands, and northeastern Venezuela through Wednesday.
