The Coast Guard is saying rip currents are a problem this weekend on Lake Michigan.

Saturday night, Coast Guard members near Holland State Park rescued seven people that were caught in the currents.

It happened about 10:15 p.m., where they helped five people caught in the rip current in the first hour. And in about a three hour span, they rescued two more.

That area had been shut down earlier in the day, but that didn't stop some people from going into the dangerous waters.

The beach at Warren Dunes is under a Red Flag Warning, meaning people need to stay out of the water.

Silver Beach is under Yellow Flag for “swim at your own risk.”

The main thing to know if caught in a rip current is not panic. The current only pulls further out, so do not try to swim against it.

Anyone caught in a current should swim parallel to the beach until they are out of the current, and then swim back to shore.

So far in 2012, there have been 39 drowning death’s on Lake Michigan.

The Coast Guard urges everyone to be careful anytime while swimming in the lake.
