 Residents on Grand Cayman waited in lines as long as three hours, stocking up on groceries. And a similar scene in Montego Bay, Jamaica, where people are snapping up water and other essentials, preparing for Barrel's Wrath, which could bring catastrophic winds and up to a foot of rain. Right now, it's about 340 or so miles from Kingston, Jamaica, maybe a little closer than that, 340 kilometers.
