MESSAGE: Tropical Storm Harvey formed east of the central Lesser Antilles. Tropical Storm Warnings are issued for Saint Lucia, Barbados, Saint Vincent and the Grenadines. A Tropical Storm Watch is in effect for Dominica.

THE SITUATION:

As at 5:00pm (EDT), three (3) low pressure systems surge over the Tropical Atlantic Ocean.

 

Tropical Storm Harvey; located 295 miles east of Barbados has maximum sustained winds of 40 mph with a minimum central pressure of 1004 mb. Environmental conditions appear generally conducive for further development while it moves westward across the tropical Atlantic Ocean into the Caribbean Sea on Friday, August 18, 2017. Heavy rainfall and gusty winds are expected to spread across portions of the Lesser Antilles tonight into Friday, and interests in the eastern Caribbean should monitor the progress of this system.

Invest 92L located 1200 miles east of the Leeward Islands continues to show signs of organization. Gradual development of this system is possible during the next day or so as it moves westward at near 20 mph.
Upper-level winds are expected to become less conducive for tropical cyclone formation when the disturbance moves north of the Leeward Islands this weekend. Formation chance through 48 hours is medium (60%).

Invest 93L is located over the far eastern Atlantic Ocean near the Cabo Verde Islands and is producing disorganized showers and thunderstorms. Gradual development of this system is possible during the next several days as it moves westward to west-northwestward at about 15 mph. Formation chance through the next 48 hours is low (near 0%) and formation chance through the next 5 days is also low (30%).

Caribbean Institute for Meteorology and Hydrology (CIMH) Weather Briefing

The Caribbean Institute for Meteorology and Hydrology (CIMH) in its Thursday August 17, 2017 briefing has advised that Tropical Storm Harvey is expected to affect the Central Lesser Antilles (Barbados north to Martinique) within the next 12 to 24 hours.

  • Other models consulted by the CIMH including the CIMH high-resolution models are in general agreement with the NHC assessment on expected rainfall accumulations of 6 – 8, with higher totals at elevated locations.
  • The likelihood of swollen rivers, localized flooding and landslides in vulnerable areas has increased due to saturated soil conditions as a result of previous rains.
  • Winds are likely to approach tropical storm force with stronger gusts in areas of thunderstorms,
  • Wave models including the CIMH model are consistent with the NHC forecast suggesting heights of 3.5 to 4 metres mainly in the area around Barbados and north to Martinique. Near shore and marine operators should therefore exercise caution.

The effects of TS Harvey will begin to be felt in Barbados this evening into Friday morning. The system is expected to slow considerably over the islands. This could produce large rainfall accumulation over the islands of Barbados, St. Vincent and the Grenadines and St. Lucia north to Martinique. It is expected to further develop as it moves in the Caribbean Sea.
