The agency’s office in Gray is forecasting snow, possibly mixing with rain along the coast this afternoon.

Snow is expected to fall after 5 a.m, with accumulations of 1 to 2 inches along the coast and 4 to 6 inches inland.

The approaching storm is already causing accidents across Connecticut and prompting numerous school delays.

Connecticut transportation officials say a tractor-trailer accident shut down both sides of Interstate 95 in East Lyme shortly before 5:30 a.m. today. It wasn’t clear when the highway will reopen.

The snow was expected to taper off later in the morning.
