often storms are forced to go west by the topography of Jamaica. sometimes once they round the NW corner of Jamaica they turn a lil more north again... that generally has happened this time, the track was more northerly a couple days ago and was expected to go thru the middle of jamaica. but it went around to the south of jamaica, as it amazingly often does, and the track has wested a bit. hopefully once it clears jamaica it will go north a bit more
