Lesser Antilles: Tropical Storm Harvey approaching region

Event

Tropical Storm Harvey has formed in the Atlantic Ocean and as of 02:00 (local time) on Friday, August 18, was located approximately 150 km (95 mi) east of Barbados. According to the US-based National Hurricane Center’s current predictions, the storm system is expected to continue to move in a westerly direction passing over the southern Lesser Antilles on Friday; it will then likely pass north of the Colombian and Venezuelan coasts, potentially hitting Central America around August 19-20.

A tropical storm “warning” has been issued for the islands of Martinique, Saint Lucia, Barbados, and Saint Vincent and the Grenadines. A lesser tropical storm “watch,” indicating possible tropical storm-like conditions, has been issued for Dominica. The French meteorological office has also issued an “orange” cyclone warning, the second-highest level, for Martinique. 

Heavy rain could result in flooding - particularly in coastal, low-lying, and river adjacent areas - as well as landslides in hilly areas. Power outages and transportation disruptions are also to be anticipated in the above areas, including flight cancelations.

Context

Tropical storms are common in the Caribbean region during the Atlantic Hurricane Season, which runs from June 1 to November 30, with a peak of storm activity typically observed in late August and September.

Advice

Individuals in the above areas are advised to follow local weather forecasts, adhere to any advice issued by regional authorities (e.g. potential evacuation orders) and confirm flight and hotel reservations. In the event of flooding, keep in mind that driving or walking through running water can be dangerous - 15 cm (6 in) of running water is enough to knock over an adult.
