The tropical cyclone alert has been discontinued for the Leeward Islands and British Virgin Islands after forecasters determined that a disturbance, designated AL92, is unlikely to develop into a tropical cyclone.

The Antigua and Barbuda Meteorological Services said the area of disturbed weather, has been affected by hostile atmospheric conditions that are limiting further development.

Despite the reduced tropical cyclone threat, the disturbance is expected to move west to west-northwest over the next 24 to 36 hours, bringing increased showers and gusty winds across the Leewards and BVI.

Rainfall totals of between 0.5 and two inches are possible, with the potential for minor flooding in low-lying areas.

Wind gusts of up to 65 km/h are also possible, with marine conditions expected to deteriorate. Seas could reach between 8 and 12 feet.

A high wind advisory and small craft warning took effect from 5 pm Friday, with mariners advised to remain in port and residents urged to secure loose objects.

Meanwhile, Dominica is also bracing for unsettled weather associated with the disturbance.

The Dominica Meteorological Service is forecasting moderate to heavy showers, with rainfall totals of two to four inches possible between Friday midnight and Saturday midday, with higher amounts in elevated areas.

Severe thunderstorms are also likely, while flooding, rising water levels in rivers, streams and drains, flash flooding, road closures and landslides or rockfall are possible.

Residents have been advised to prepare emergency kits, know their safe routes, keep drains and gutters clear and check on vulnerable relatives, friends and neighbours.

In Guadeloupe and Martinique, an orange alert is in effect for strong winds, rough seas, heavy rain and thunderstorms, while Saint Martin and St Barts are under a yellow alert.
