Hurricane Hermine is forecast to be off-shore this weekend, which could make for a rainy, windy Labor Day.
The National Weather Service has a Hazardous Weather Outlook which says the hurricane could hit Southern New England from Sunday into Tuesday with rain and strong winds. The track of the storm, however, remains uncertain, so the impact may change.
Due to the Labor Day holiday, trash collection in Watertown will be pushed back a day, so those normally with Monday pickup will be Tuesday, etc.
Also, Town Hall and the Watertown Free Public Library will be closed for the holiday. Banks will also be closed Monday.
The MBTA will be running on a Sunday schedule on Labor Day. See more info here.
