Bill weakens, waves dont as storm heads to Nova Scotia
August 21, 2009
The latest guidance from the NHC shows Bill has weakened slightly to a strong Cat-2 hurricane after encountering some moderate shear. There is a good chance the system will reorganize as shear diminishes and hits warmer waters Friday. However the forecast shows Bill slowing to a weak Cat-2/strong Cat-1 as Saturday progresses.
The forecast models are in good agreement on the track, taking Bill due North Friday night, before making a NE turn into Sunday.
The greatest threat to the US will be in the form of coastal erosion as high seas will affect the eastern seaboard from Florida to Maine. The highest expected seas will occur near Cape Cod, which could experience 20′ waves. The threat from rip currents is moderate and expected to increase as Bill travels North.
We will continue to monitor the system and provide updates as necessary.
