Forecast for Sean
The latest SHIPS model forecast predicts wind shear will remain about where it is now through Friday morning. However, ocean temperatures will gradually cool to 24°C during this time, and it is questionable whether Sean will have a favorable enough environment to strengthen into a hurricane. The computer models show little development of Sean, with none of our reliable models predicting it will become a hurricane. Bermuda is the only land area that need concern itself with Sean, as the storm is now caught in a trough of low pressure that will accelerate the storm to the northeast. The center of Sean could pass close enough to Bermuda to bring the island heavy rain squalls and sustained winds of 40 - 45 mph on Friday. NHC is giving a 52% chance that Bermuda will receive tropical storm-force winds of 39 mph. Wind shear will rise to 30 - 50 knots on Friday, which should be able to rip the storm apart by Saturday.
