The National Hurricane Center has increased the likelihood of the tropical disturbance currently 1150 East-Southeast of the Windward Islands becoming a tropical depression/storm to 60%. Satellite data is indicating that the precursors to an 'eye' are forming so it's very likely that we could be seeing Chantal being named anytime within the next couple days.
[Update] They've bumped the percentage up to 70%. My guess is we'll see it become a depression/storm by tomorrow. A 'Hurricane Hunter' flight is scheduled to fly through it Monday.
