Advisory # 4 on Tropical Storm “Dorian
At 5:00 am Tropical Storm ‘Dorian’ was centered near 11.9 North…56.4 West or about 335 miles (540 km) east-southeast of St. Vincent. Maximum sustained winds have increased to near 60 mph (95km/h), with tropical-storm-force winds now extending outward up to 45 miles (75 km) from the center. The minimum central pressure is 1002mb (29.59 inches).
The system continues to move towards the west at 14 mph (22 km/h) and on this track, the center of the “Dorian” is expected to pass near or over St. Vincent early Tuesday morning.
Sustained surface winds between 58 to 70 mph (93 to 113km/h) with higher gusts are expected to spread across St. Vincent and the Grenadines early Tuesday morning, persisting into the afternoon.
In addition, pockets of moderate to heavy showers and thunderstorms are expected to move across the islands from early Tuesday morning. Rainfall accumulations of at least 3 to 5 inches (75 to 125 mm) are possible with isolated higher amounts. As a result, some flash-flooding are likely in low-lying areas and near rivers and streams.
Large easterly to south-easterly swells of 2.5 to 3.5 meters (8 to 12 feet) 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 12 noon today, Monday 26th August, 2019. Sea-bathers and other users of the sea are also advised to stay out of the water.
In this case, a Small-craft Warning means that mean wind-speeds of 50 to 60 knots (93 to 113km/h) and/or seas equal to or greater than 3 meters (10 feet) 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:
1:37 pm today, and 2:20 am and 2:24 pm on Tuesday
Residents are advised to make the necessary preparations and keep updated on the progress of this system.
