MBTA Winter Storm Advisory

Posted on March 13, 2023

Due to forecasted high winds and direction of wind gusts, MBTA ferry services will be suspended Tuesday.

In advance of a winter storm impacting the state tonight and through Wednesday, the MBTA and Keolis Boston are preparing the system prior to the arrival of snow and forecasted high winds. In addition, the MBTA is advising customers to subscribe to T-Alerts for the most current service information as the storm may cause downed trees and other impacts that could affect normal schedules. Riders are also encouraged to follow @MBTA and @MBTA_CR on Twitter and visit the T’s Winter Travel Guide at

Service disruptions may occur on the MBTA’s subway lines due to the winter storm. Riders are also reminded that longer headways continue on the Red, Orange, Blue, Green, and Mattapan Lines this week as MBTA engineers continue to perform repair validations and speed verifications following a Department of Public Utilities (DPU) site visit last week. Due to forecasted high winds and the potential for damage to the 75-year-old trolleys, service on the Mattapan Line will be replaced with shuttle bus service tomorrow. Disruptions in service will be listed on T-Alerts and on Twitter @MBTA.

Regular weekday bus service is expected to operate tomorrow. If weather conditions worsen, some bus routes may operate on their Snow Routes and will be re-routed to avoid steep hills, tight corners, and narrow streets. During the storm, the MBTA will post a T-Alert for each bus line that’s running on its Snow Route.

All Commuter Rail lines will operate a regular weekday schedule tomorrow. Disruptions in service will be listed on T-Alerts and on Twitter @MBTA_CR.

Due to the forecasted high winds and direction of wind gusts, all ferry services will be suspended tomorrow.

RIDE services will be unaffected tomorrow and will operate as planned.

While crews will be working to clear snow and ice throughout the transit system tomorrow, MBTA riders are asked to use caution on platforms and at bus stops.

The MBTA will operate non-passenger trains to assist in keeping tracks clear and to look for any trees or branches that pose a threat to overhead wires. MBTA emergency crews are on standby throughout the storm to respond to rail issues, issues affecting power systems, potential switch problems, and any flooding issues that may occur. Power crews will be on hand to inspect overhead wires on the Blue and Green lines for ice buildup on catenary wires. Crews will use ice cutters, installed on vehicles, to safely remove ice from impacting power lines. Increased staffing will be on-site throughout the duration of the weather event to respond to weather-related issues, and rail-borne snow-fighting equipment will be pre-deployed at key locations around the rapid transit network. The T also has contractors at the ready for snow clearing along key bus routes and T facility/employee parking, freeing up T personnel to concentrate on core system functions.
