A statement issued by the acting Director of the Charnock Christ Church-based office Sonia Nurse, around 4:30 pm on Friday, September 20 said meteorologists were monitoring the progress of a strong tropical wave now near 48°W, south of 15°N. She also said an accompanying area of low pressure is along the wave axis, near 10°N 48°W, about 800 miles, or just about 1,300 km east-southeast of Barbados.

“Forecast models are suggesting some potential for further development as the system approaches Barbados and the southern Windwards late Saturday, early Sunday. Regardless of development, brisk surface winds of 25 to 30 knots or about 45 to 55km/h, with higher gusts and pockets of moderate to heavy showers are anticipated with rainfall accumulations of 75 to 100mm or about three to four inches is possible during the passage of this system.

“In addition, a gradual deterioration in sea-conditions is also expected with east southeasterly swells of 3.0 to 4.0m or 10 to 13 feet likely. Thus, a High-Surf Advisory and Small-Craft Warning will be in effect from 8 am on Saturday, September 21 to Monday, September 23,” Nurse noted in the statement.

A High-Surf Advisory is issued when breaking wave action poses a threat to life and property within the surf zone, while a Small-Craft Warning means in this case, that wind-speeds of 25 to 30 knots or 45 to 55km/h and or seas greater than 3m, (10 feet) will be affecting the marine area.

“The BMS will continue to closely monitor the progress of this tropical wave and will issue further updates during the course of the weekend. It may become necessary to issue a Flash Flood-Watch/Warning at short notice. Resident in Barbados should continue to monitor the progress of this wave.”
