MONTAUK - If you're ready to cool off in the ocean, beware on the East End.
Officials say Portuguese man-of-wars are washing up.
The creatures have been seen at Hither Hills in Montauk, Tiana Beach and a number of Southampton spots.
Experts say the man-of-wars are passing through on their journey north. They are expected to be gone by this weekend.
This is the first Long Island man-of-war sighting in seven years.
