Boston declares snow emergency

Snowfall accumulations between 4 and 8 inches were expected near the New England coastline by Sunday morning as another wave of winter weather moved along the East Coast, according to forecasters.

Boston Mayor Thomas Menino declared a snow emergency and parking ban that went into effect at 9 p.m. Saturday.

"With up to 8 inches of snow expected in parts of the city, and freezing temperatures forecast for the next week, it's extremely important we get our roadways cleared as soon as possible in the interest of public safety," Menino said in a statement.

About 200 pieces of equipment were to be deployed on Boston roadways Saturday evening.

Heavy snow also was expected overnight in portions of Maine and New Hampshire.

Lighter and scattered amounts were expected Sunday across much of New England, the Appalachians and the Upper Great Lakes, according to the National Weather Service.

Snow covers 64% of the ground in the lower 48 states, according to the National Oceanic and Atmospheric Association. Last winter's top snow coverage for the lower 48 was nearly 48%.

Storm-related incidents have been blamed for the deaths of at least 10 people nationwide, including two children in Arkansas.
