A Flood-Warning means that flooding is already occurring or is likely to occur.
The combination of a tropical wave, a trough system and the Inter-Tropical Convergence Zone (I.T.C.Z) has been generating pockets of moderate to heavy showers and isolated thunderstorms across portions of the Lesser Antilles during the last several hours, and some of this activity will start to affect St. Vincent and the Grenadines this afternoon and into tonight.
Fluctuations in the intensity of the showers, scattered thunderstorms along with occasional gusty winds are expected to persist for at least the next 24 to 48 hours. Rainfall accumulations of 2 to 4 inches (50 to 100 mm) with isolated higher amounts are possible across the islands as these systems linger over the area into early Wednesday.
Thus, a Flood-Warning and a Small-craft Warning have been issued and will remain in effect until further notice.
Residents and motorists in flood prone areas, areas prone to land slippage, near rivers and streams should exercise caution and remain alert.
A small-craft Warning means in this case that seas equal to or greater than 3m (10ft) and wind speeds of 20 to 25 knots (23 to 29 mph) will be affecting the marine area.
The Barbados Meteorological Services and the St Vincent and the Grenadines Services will continue to monitor these systems and provide the necessary updates.
