The National Emergency Management Organisation (NEMO) is urging all residents of St. Vincent and the Grenadines to be prepared and continue to listen to your radio stations for further updates as a tropical watch was issued for the country Friday night.
The meteorological service of Barbados at 11 p.m. Thursday issued a Tropical Storm Watch for St. Vincent and the Grenadines.
A tropical storm watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.
The tropical storm watch was issued as Tropical Storm Bertha formed in the Atlantic season.
At 11 p.m., the centre of Tropical Storm Bertha was located near latitude 12.3 North, longitude 55.5 West.
Bertha is moving toward the West-Northwest near 20 miles per hour (mph) (31 kilometres per hour (km/h) and this general motion is expected to continue for the next couple of days.
On the forecast track, Bertha is expected to pass near Barbados Friday afternoon and move through the central Lesser Antilles Friday evening.
Reports from an air force reserve reconnaissance aircraft indicate that maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Little change in strength is forecast during the next 48 hours. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the centre.
The estimated minimum central pressure is 1008 millibars (29.77 inches).
