Moderators StretchCT Posted July 1 Author Moderators Share Posted July 1 Quite a few boats stayed in Grenada, but in pretty well sheltered areas. Winds with the storm passing to the north should be NE, N, NW then maybe some strong from the SW. Most of these spots look pretty good. Link to comment Share on other sites More sharing options...

So basically if they were in Grenville or Mount Carmel, the boats would be open to possibly a lot of damage? Link to comment Share on other sites More sharing options...

Beryl is nearing the southern Windward Islands and expected to make landfall within the next hour or two. This is an extremely dangerous and life-threatening situation. Take action now to protect your life! Residents in the Grenadine Islands and Carriacou Island should not leave their shelter as winds will rapidly increase within the eyewall of Beryl. Remain in place through the passage of these life-threatening conditions and do not venture out in the eye of the storm. A weather station located in Barbados at Grantley Adams International Airport recently reported a sustained wind of 52 mph (83 km/h) and a gust of 69 mph (111 km/h).

Yes, I'm also not sure about St Georges, seems a little too exposed once it passes. My friend says its sheltered enough. N to S, Grenada is 15NM. The eye is listed as 18NM. Looks like the southern eye wall might nick the northern part of Grenada. The islands north are toast. 1 Link to comment Share on other sites More sharing options...

Burr Posted July 1 Share Posted July 1 (edited) The ‘larger’ island in line for landfall is Carriacou, for reference in the maps above, with Union Island and the ‘Petites’ Martinique and St Vincent also in the path of the northern eyewall.
