Tropical Wave Axis Is Expected To Traverse Grenada Overnight Into Saturday Morning

Synopsis: At 8:00 am, the axis of tropical wave #23 was located along 56-57W south of 18N, 443nm east of Grenada. This wave is moving west near 15 to 20 kt. Scattered moderate convection  is evident along the ITCZ south of 12N between 40W and 53W. 

Projected track: The system will continue to move on a westerly track, traversing the Lesser  Antilles by Friday night. 

Forecast for the State of Grenada: Grenada, Carriacou and Petite Martinique can expect cloudy to overcast conditions with showers (which may become heavy) and a medium chance of thunder  as a result of this wave on Saturday. These conditions are expected to linger into Sunday since  there is a trailing band of ITCZ moisture to the east of the wave. Weather models suggest rainfall  accumulation of 2 to 3 inches with greater amounts at higher elevations. Marine users are urged to  exercise extra caution when venturing out to sea. 

Potential Impacts

Street and flash flooding  

Landslides and rock fall 

Agitated seas and above normal swells. 

The Met Office continues to closely monitor the progress of this system as it propagates  towards the island chain and will provide updates in a timely manner. 

Next update will be issued at 8 pm.
