Before the Barney's posted their latest video showing the jelly fish on the beach, I hadn't realized how wide spread the phenomenon was. Here's an article with more about them. Add to the warnings, not to drive your car over them or it will stink for days! Thumb's Up

Velella is an offshore resident. Winds blowing gently against its triangular, clear sail move the jellyfish. The sail is set diagonally to the long axis of the animal. On our side of the north Pacific Ocean, their sails are set in a northwest to southeast direction. On the other side of the north Pacific, the sails are set in a northeast to southwest direction. In the southern hemisphere, sails are reversed. As long as the winds blow gently, Velella tacks at about 45˚ away from a following wind. This keeps the animal offshore.
When winds are strong, Velella loses its tacking ability and begins spinning and more directly follows the wind. Strong westerlies, then, are what drive these animals onto our beaches.

You mean "weeks". Your car will stink for weeks. Mine can prove it.
