The warm spell will continue Tuesday in Boston, offering a pleasant break from winter’s misery as the New England Patriots celebrate their Super Bowl victory with a rolling rally through the city that is expected to attract about 1 million fans.

With the Patriots nabbing their sixth Super Bowl less than four months after the Red Sox won the World Series, Boston is accustomed to celebratory parades, but officials asked fans to take precautions and mind their behavior if they plan to cheer the Pats during their victory lap. Here’s everything you need to know about the festivities.

The parade is set to begin at 11 a.m. and last about an hour, ending at Government Center but without a rally on City Hall Plaza, Mayor Martin J. Walsh said at a news conference Monday.

The duck boats will launch from Boylston Street near the Hynes Convention Center and continue to Tremont Street, where they will turn left and continue along Boston Common and on to Cambridge Street. This is the same route the parade took following the Patriots’ 2017 win.

PUBLIC SAFETY Walsh stressed Monday that no public drinking or marijuana smoking will be allowed and asked fans not to throw beer cans or other projectiles, citing the cans that struck Red Sox manager Alex Cora and a World Series trophy at the October parade.

“Just like our Patriots, who showed the world what Boston’s all about, we win with class, we celebrate with class,” Walsh said. “And part of our celebration of our team is showing respect for the city of Boston.”

Police Commissioner William Gross encouraged parents of teenagers attending the parade to check them for alcohol, noting that it could be disguised as a different liquid.

“We’ve had to take several teenagers to the hospital” during past parades, Gross said.

STREET CLOSURES Starting about 9 a.m. Tuesday, the city will close Boylston Street between Massachusetts Avenue and Tremont Street, Tremont between Boylston and Court streets, and Cambridge Street from Court to New Chardon streets.

When those streets reopen will depend on the size of the crowd, the city said. “We’ll re-open each street after people leave and we get a chance to clean up. We expect to re-open Boylston Street first, followed by Tremont Street and then Cambridge Street,” officials said.

PARKING RESTRICTIONS City officials ask that anyone parking near the route be sure to check the posted street signs and watch for temporary signs reading, “No Stopping. Boston Police Special Event.” In those areas, workers will begin towing parked vehicles at 6 a.m., the city said.

As of Monday, Charles Street was already closed to parking between the Public Garden’s center gate and Beacon Street. On Tuesday, there will be no parking allowed on sections of multiple streets near the parade route.

THE MBTA The MBTA cautions that crowds flocking to the celebration will make trains and platforms unusually busy. Government Center and Bowdoin stations may be closed temporarily, but nearby stations such as Downtown Crossing, State, and Haymarket are expected to remain open.

Trains on the Green, Red, Orange, and Blue lines will run on a weekday schedule, with rush-hour service levels throughout the day. MBTA bus routes 9, 39, 43, and 55, and Silver Line routes 5, 92, and 93 will detour around the parade route, the T said.

Those needing to pay for roundtrip travel on the T are encouraged to buy their tickets or passes in advance (a single roundtrip fare on a Charlie Card will cost $5).

The transit authority encouraged those who need to use MBTA parking lots to carpool if possible and check the Twitter account @MBTA_Parking for updates on some of the busiest lots. The T recommends visiting www.mbta.com/patriots for full details on the parade’s effects on the system.

MBTA Transit Police Chief Kenneth Green urged users to notify authorities if they see or hear anything suspicious on the system.

COMMUTER RAIL Travelers should also expect extra riders on the MBTA’s commuter rail system, which will add cars to its trains Tuesday, officials said. Bicycles, including folding bikes, will not be permitted on commuter rail trains on Tuesday, the T said.

The T encourages both business commuters and parade-goers to make their journeys well before the parade begins and to leave Boston before evening rush hour to avoid the biggest crowds. Some commuter rail trains may begin running express routes after reaching capacity, express trains may make extra stops, and trains may wait past their scheduled departures until they reach capacity, the T cautioned.

Those who aren’t headed to the parade and can work remotely may want to avoid the city entirely, the T suggests.

Walsh recommended that parade-goers consider walking or riding bicycles from Bluebikes, the regional bike share service, or watching the parade from home on television.

PREPARATIONS Workers readied duck boats for the rally on Monday, pausing during Boston Duck Tours’ winter maintenance period to get the boats road-ready, according to Cindy Brown, chief executive for the tour company.

In addition to standard preparations for the duck boats, workers will remove seats from the rear section of 15 or 16 of the vehicles and install wooden platforms for Patriots players to stand on so they are visible to the crowd, Brown said. A spare boat and a mechanic will be available in case of any mechanical issues, and the boats used in the parade will be thoroughly checked out.

“They have to put on sound systems, and confetti machines, and the banners, and the sponsors, and the signage,” Brown said in a telephone interview, adding that the effort is “more work than it looks like.”

A February parade also means calling back summer employees to drive the duck boats. Drivers were notified that they could be called into service, Brown said, because parade preparations begin when it becomes clear a local sports franchise has a chance of victory in its league.

Fortunately, Brown said, the conditions for this year’s parade are about as good as they could be in February. “A day like tomorrow — with 57 degrees and sunny — is a dream for this,” she said.
