As Tropical Storm Hermine works its way up the coast after hammering Florida, New England weather forecasters have issued tropical storm warnings along the Northeast coastline, along Rhode Island and through Cape Cod, including the Islands.

A hazardous weather outlook was issued this morning for Massachusetts and Rhode Island coastal waters, expected to be rough going beginning as soon as Sunday afternoon.

Forecasters are keeping a close eye as Tropical Storm Hermine leaves Florida and heads back offshore. Its impact is expected to be felt along the coastline as it continues to make its way toward the Northeast.

The National Weather Service says "tropical storm force winds associated with Hermine may develop across the waters during the day on Sunday and persist at least through Monday morning." Sea levels will rapidly and dangerously grow through Sunday night.

Today's beautifully comfortable September weather can be enjoyed without looking over your shoulder at the skyline. You're better off the farther inland you are, but you may want to rethink Labor Day trip to the Cape.

The National Weather Service said the south coast and Cape and Islands should expect "two rounds of tropical storm force winds," one Sunday afternoon through Monday morning, and another Tuesday and Wednesday.

By the time Hermine is all said and done, it appears forecasters think Rhode Island and the Massachusetts southeastern coast and Cape and Islands could suffer from some coastal flooding and beach erosion, but the exact track of the storm is still unknown.
