According to the Facebook post, cold water temperatures, winds and currents can all cause jellyfish to wash ashore.
"Jellyfish can’t swim, so they float along with the winds and currents," experts explained.
Cannonball jellyfish don't usually sting, but people are asked not to handle them. Officials will not attempt to remove the jellyfish, letting nature take its course.
"Some may wash back out with the tide or become food for other living things on the seashore like birds or crabs," the post explains.
