While some areas issued Winter Storm Watch, updated forecast shows major change in possible snow accumulation

An updated forecast shows the potential of a major change in snow accumulations involving next week’s storm.

According to the National Weather Service, a Winter Storm Watch is now in effect from 7am Monday through 1 PM Tuesday for the communities in blue. Snow accumulations could reach 6-12 inches. Hazardous road conditions expected during the evening commute on Monday.

The expected snow totals for southeastern Massachusetts, however, have significantly decreased due to a more western track of the storm along with warmer temperatures.

Strong winds may still result in scattered and isolated power outages across eastern Massachusetts and Rhode Island which may also include some downed trees.

Coastal flooding and beach erosion will be possible along the eastern Massachusetts coastline during high tide.
