Hurricane FAQ

Cape Verde-type hurricanes are Atlantic basin tropical cyclones that develop into tropical storms fairly close (<1000 km [600 mi] or so) to the Cape Verde Islands and then become hurricanes before reaching the Caribbean. Typically, this may occur in August and September, but in rare years (like 1995) this may occur in late July and/or early ...
