The forecast does not call for Hurricane Erin to get too close to Massachusetts, but the storm is causing some beaches to close for swimming as it could create big waves and dangerous rip currents on the coast. Gov. Maura Healey asked residents on the coast to "stay safe and alert" as Erin passes by.

"Fluctuations in strength are expected during the next couple of days. However, Erin is likely to remain a dangerous major hurricane through the middle of this week," the agency said.

Hurricane Erin may become a Category 3 Hurricane on Wednesday.

The authorities there have ordered a mandatory evacuation of the islands of Hatteras and Ocracoke, warning that the main highway linking them to other islands could become impassable.
