Grenada Experiencing Agitated seas on the West Coast

The Grenada Meteorological Service has advised the National Disaster Management Agency (NaDMA) that it is currently monitoring convective activity associated with a tropical wave approaching the Windward Islands.

Synopsis:
Recent satellite wind data and surface observations indicate the tropical wave currently crossing the Windward Islands still lacks a closed circulation. However, both radar and satellite images indicate the associated shower and thunderstorm activity is starting to show signs of organization. The system is still moving quickly westward at 20 to 25 mph, which could limit development over the next day or so, but environmental conditions are forecast to become more favorable as it slows down in the central Caribbean Sea by the middle of this week. A tropical depression is likely to form by the middle to latter portion of this week in the central Caribbean Sea. Regardless of development, heavy rainfall and gusty winds are expected to continue for portions of the Windward and Leeward Islands through Monday morning. Formation chance through 48 hours, low, 30 percent. Formation chance through 7 days, high, 70 percent.

Forecast for the State of Grenada:
Models suggest convection associated with this tropical wave may lead to moderate showers,
which may become heavy at times, with possible thunder through Monday Morning.

Flash flood and landslide advisories are currently in effect.

Please note that there are no watches or warnings in effect for the State of Grenada.

Residents should expect heavy, showery activity and gusty winds during the next 24 to 36 hours.

Citizens are urged to monitor the weather conditions and pay attention to the information issued by the Meteorological Service and NaDMA.

The Meteorological Service and NaDMA will continue to monitor the weather and provide updates as necessary.
