The city of Boston says that the snow emergency that went into effect yesterday will be lifted at 6 p.m. on Monday. The emergency order means that parking is prohibited on all major arteries in Boston.

In a noon hour press conference on Sunday, Gov. Deval Patrick said that service on the Mattapan high-speed trolley line would be suspended tonight and replaced with buses. All other public transportation is expected to follow a normal schedule.

"Residents are reminded to remain at home throughout the duration of this snow event and businesses tomorrow should consider asking employees to work from home," stated a press release issued by the city of Boston on Sunday morning. The city also is cautioning older residents or those with "health conditions" to "refrain from shoveling this heavy wet snow."

The City of Boston has a Storm Center operating and residents can call its 24-Hour Hotline at (617) 635-4500 with storm-related concerns. Some other instructions from City Hall include:

• On streets other than major arteries, do not park within 20 feet of an intersection or further than one foot from the curb, as this impedes access for both emergency vehicles and snow plows.
• Parking space savers must be removed no more than 48 hours after a snowemergency is lifted. The City's Department of Public Works will remove space savers left out beyond this period.
• Do not throw snow back into the street. "Throwbacks" force the city to remove snow from the same street twice.
• Shovel out fire hydrants, catch basins and pedestrian ramps close to your home.
• Property owners are reminded to shovel snow from sidewalks that abut their homes and businesses and any handicapped ramps close to your homes or business.
• Please check on elderly neighbors and others in need.
