Harbor Homes will be opening warming centers this week in anticipation of freezing temperatures.

The Vineyard’s only overnight winter shelter will open next week at a new location.

Harbor Homes will operate its winter emergency homeless shelter in a new location this season after the Oak Bluffs zoning board of appeals approved a temporary conversion of its women’s group home for a new use.

Fights at a homeless encampment near the park and ride in Tisbury earlier this month have led the town to begin enforcing bylaws that prohibit camping.

Harbor Homes of Martha’s Vineyard, the Island’s homelessness prevention nonprofit, announced this week that Brian Morris has resigned as executive director, effective April 30.

The manager of the Vineyard’s only homeless shelter has been going to the Island town governments in recent weeks in the hope that they will join Harbor Homes to start a committee or task force aimed at helping the growing homeless population.
