A tropical storm watch is in effect for St. Vincent and the Grenadines.
This means that tropical storm conditions are possible within the watch area, generally within 48 hours.
Forecaster say that 11 a.m. Sunday, Tropical Storm Dorian was centred near 11.2 North 52.9 West or about 575 miles (925 km) east-southeast of SVG.
Maximum sustained winds are near 40 mph (65km/h), with tropical-storm-force winds extending outward up to 25 miles (40 km) from the centre.
The minimum central pressure is 1008mb (29.77inches).
The system is moving towards the west at 14 mph (22 km/h) and on this track, the centre of Dorian is expected to pass north of mainland St. Vincent late Monday/early Tuesday.
Sustained surface winds between 25 to 35 mph (40 to 55 km/h) with gusts to storm force are likely to spread across SVG from late Monday and persist into Tuesday.
In addition, pockets of moderate to heavy showers, periods of rain and scattered thunderstorms are expected.
Rainfall accumulations of at least 2 to 4 inches (50 to 100 millimetres) are possible from late Monday into Tuesday with isolated higher amounts.
As a result, some flash flooding is likely in low-lying areas. Residents are urged to be on the alert and take all necessary precautions.
Large easterly to southeasterly swells of 2.5 to 3.5m (8 to 12ft) are also forecast to accompany the system. Low-lying coastlines around the islands will be particularly vulnerable at times of high tide. Large waves and dangerous rip tides can be expected. These will create unsafe conditions for small-craft operators and fishermen.
Consequently, a High-Surf Advisory And Small-Craft Warning will be in effect from noon on Monday until 6 p.m. Tuesday.
Sea-bathers and other users of the sea are also advised to stay out of the water.
A small-craft warning means in this case that mean wind-speeds of 25 to 33 knots (47 to 62 km/h) and/or seas equal to or greater than 3 metres (10ft) will be affecting the marine area.
A high-surf advisory is issued when breaking wave action poses a threat to life and property within the surf zone.
High Tide are expected around:
1:27 a.m. and 1:37 p.m. on Monday; 2:20 a.m. and 2:24 p.m. on Tuesday, and 3:20 a.m. and 3:16 p.m. on Wednesday
The next advisory will be at 6 p.m. today, Sunday.
