Yet another storm! This one will be lighter on the snow down on the coast, but will be long in duration. The long duration of high wind speed is expected to cause very high seas off the coast and potentially lead to flooding. A look at the data from Buoy 44013 from wunderground.com shows that recorded wave heights exceeded 20 feet for most of Thursday and Friday.
Universal Hub has all the details on the impact in Boston. Here are some photos below of the surf as it hits the South Shore. These were taken from Cohasset on March 7th about an hour after high tide:
