An intense storm hitting Boston Wednesday caused flooding that shut down a highway tunnel in the city and knocked out power for tens of thousands.

The on-ramp from Congress Street to Interstate 93 was flooded Wednesday night, Massachusetts State Police said. Traffic was being diverted and the Massachusetts Department of Transportation was bringing in emergency crews to pump the water out.

As of around midnight, fewer than 9,500 customers remained without power, down from over 24,000 around 7 p.m., according to the Massachusetts Emergency Management Agency.

Also facing power issues were MBTA Commuter Rail trains that run to South Station — at Back Bay, a downed catenary wire, the line that provides power to trains, was causing significant delays to and from Boston. Adding to the problems was a disabled Amtrak train, the T said.

Separately, a downed tree near Four Corners/Geneva Station in Boston caused at least two trains on the Fairmount Line to be canceled, the MBTA said.

A major storm has made for a rough evening commute Wednesday across New England.

Fire officials in Taunton say part of the edge of a roof collapsed on Main Street, with crews removing the rest so the wind wouldn't knock it down. No one was injured.

The storm was expected to bring some localized flooding — a flood watch was in effect for parts of central and western Massachusetts and southern New Hampshire through Thursday morning.
