Hurricane Erin was a Category 4 storm again Monday morning and is expected to grow even larger and stronger, according to the latest advisory from the National Hurricane Center. Although Erin is forecast to move north between the U.S. and Bermuda, life-threatening surf and rip currents are likely across the Atlantic coast from Florida to Canada.

As Hurricane Erin tracks northward in the Atlantic, its broad wind field is expected to churn up rough seas and dangerous rip currents along Florida’s east coast this week, forecasters and county officials warned.
