Rough surf conditions and dangerous rip currents have forced many beaches to ban swimming and boogie boarding this week.

Two more tropical systems trail Hurricane Erin, which is following a projected course that brushes past the East Coast without making landfall.

Hurricane Erin is expected to grow in size and strength as it moves north through the Atlantic this week. Forecasters expect it to pass well offshore of North Carolina on Wednesday and Thursday, but say it likely will cause coastal flooding and erosion, along with dangerous rip currents.

Hurricane Erin weakened to a Category 3 hurricane overnight, but still remains a formidable major hurricane. Erin had max winds of 125 mph, the National Hurricane Center said in a 5 a.m. ET update. The next update is expected at 8 a.

Forecasts nudge Erin's likely path to the west, increasing the risks at U.S. beaches. Experts say the storm's massive size, rather than windspeed, is what makes it a threat.

The first Atlantic hurricane of 2025, Erin reached Category 5 status before weakening somewhat and becoming a Category 4 storm, with maximum sustained winds of 140 mph (220 kph), according to the National Hurricane Center in Miami.
