Moisture and instability associated with the passage of a tropical wave Wednesday night into Thursday and a second wave late Friday, is expected to produce cloudiness, showers and thunderstorm activity across parts of the island chain, including Dominica.
Thereafter, a wet pattern is expected to linger across the island chain into early next week.
As a result, persons in areas prone to flooding, landslides and falling rocks are advised to exercise caution throughout the period.
Moderate seas are expected during the next 24 to 48 hours with waves peaking near 7.0ft. A Small craft warning is in effect for above normal westerly swells. Small craft operators and sea bathers, particularly on the west coast, should exercise caution.
Meanwhile the Office of Disaster Management (ODM) has alerted the public that there is a strong tropical wave approaching the Windward Islands.
Locally heavy rains and gusty winds are possible in the Windward Islands and Southern Leewards during the next couple of days as the system moves through the area.
Given that the island has been experiencing rainfall over the last few days, the grounds are likely to be saturated. This condition provides an opportunity for flooding, the ODM said.
It said residents who are living in unsafe areas are asked to be cautious as they go about their daily routine.
The ODM has advised residents to monitor the movement and progress of the Tropical Wave, listen to their local radio stations for weather reports and be prepared to take action at short notice.
