With multiple shark sightings over the weekend on Cape Cod, at least one swam close to Nantucket and was seen near Cisco Beach. Nantucket Harbormaster Sheila Lucy reported a confirmed sighting via Twitter a little after 9:30 Saturday morning then ordered adjoining South Shore beaches closed for two hours.
The shark warning for Nantucket was called off around noon, but a purple warning flag soon reappeared for a school of jellyfish near the beach. In both cases, the beach remained beautiful for reading and sunning.
You're gonna need a bigger boat!
