Avila Beach still closed
A second shark siting in less than a week.
Just when Avila Beach was about to reopen, the Port San Luis Harbor District closes the water for another five days.
Port officials said there was a credible shark sighting about 100 yards off the beach around 7 a.m.
The witness claimed she saw a Great White Shark.
The waters have been off limits since Friday night, when a local fisherman said he saw a Great White in the harbor.
The last fatal shark attack was in August of 2003.
While the beach will remain open, the water is off limits through Labor Day weekend. It is set to reopen on Monday at 7 a.m.
