Tropical Storm Don is located east-southeast of the Windward Islands with maximum sustained winds near 45 mph. Currently, the system is over warm waters and a low-level shear environment which may result in some strengthening. Once the system enters the eastern Caribbean Sea, however, strong low-level easterly flow accompanied with strong upper-level westerly flow will diminish Don. The National Hurricane Center is forecasting the lifespan of Don to be 72 hours. Tropical Storm warnings have been issued for Grenada as conditions are expected to deteriorate within the next 24 to 36 hours. Tropical Storm watches have been issued for Barbados, St. Lucia, St. Vincent and the Grenadines. Rainfall amounts up to 4 inches are possible in the Windward Islands through Wednesday morning. Tropical-storm-force winds are to be expected in Grenada on Tuesday. The next advisory will be 11:00 PM AST.
