High surf and rip currents are expected this week on Lowcountry beaches, according to the National Weather Service.
A new moon and lunar perigee -- when the moon is closest to Earth -- will lead to higher than usual tides, which started Tuesday, the service said.
Then on Thursday, local beaches should start to see rip currents and powerful waves that will continue through the weekend. This higher surf will be a side effect of Tropical Storm Ana and Hurricane Bill's churning of the Atlantic Ocean, the service said.
The combination of high tides and surf could lead to beach erosion, the service said Tuesday.
