Weather disturbance lacking defined circulation

As Barbadians hanker down and prepare for heaving rain and some high winds this evening into tonight, the Barbados Meteorological Services say it is continuing to monitor the progress of a strong tropical wave with its axis, around 5 pm, near 58°W, south of 15°N.

A statement issued earlier this evening by the Met office said a hurricane hunter investigated the system this afternoon and found that the wave lacked a well-defined circulation.  It also said that although the system continues to be disorganized, some gradual development remains likely later this weekend or early next week as the system moves quickly westward crossing Barbados and the Windward islands later tonight into tomorrow.

The statement from the Met Office also stressed that regardless of development, brisk surface winds of 25 to 30knots, or about 45 to 55km/h, with higher gusts, pockets of moderate to heavy showers are anticipated with rainfall accumulations of 75 to 100mm or three to four inches was possible during the passage of this system.

They also noted that deteriorating sea-conditions with east-southeasterly swells of 3.0 to 4.0m or 10 to 13 feet were likely and hence, a High-Surf Advisory and Small-Craft Warning will be in effect from today, Saturday, September 21 to Monday, September 23.

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 3o knots or 45 to 55km/h and or seas greater than 3m or 10 feet will be affecting the marine area.

The Met office says it will l continue to closely monitor the progress of this tropical wave and will issue further updates as conditions warrant.
