     WASHINGTON(Reuters)-Federal Government Agencies in the capital region will remain closed

for a second day on Tuesday as residents trying to clean up the weekend storm that shocked the area

with two feet of snow.

     Another big winter storm was expected to hit the U.S. mid-Atlantic on Tuesday and last through

Wednesday, the National Weather Service forecast on Monday. Projected snowfall is ranged from

10 to 20 inches, it said. The new storm was expected to hit other big cities along the East Coast,

including Baltimore and Philadelphia, which is still extending into New Jersey and New York. It would

pile on to the 32 inches of snow that fell in suburban Washington in the biggest snowfall to hit the city

in decades.

     The Office of Personnel Management announced on Monday evening that Federal Government

Offices in the Washington area would be closed on Tuesday. Emergency employees were expected

to report for work in time, but non-emergency employees were excused. The Federal Government

was closed on Monday, though President Barack Obama still held meetings at the White House.

Schools and most businesses in the region also were shut.

     In the county, about 80,000 people lost power on Saturday, and some customers still had no

electricity or heat on Monday. Many schools said classes would be canceled through Tuesday, even

before the latest storm warning.

     On Monday, winter sunshine bathed the nation's capital and the surrounding region, where people

dug out their driveways and sidewalks to finally start to clear streets in some residential neighborhoods.

Bus service on Monday was limited to just a small number of routes in the Washington, D.C.

     Cold and snow blanketed much of the central United States this winter, slowing weight gain in cattle

and pigs, delaying livestock(牲畜)sales, and increasing feed costs for producers.

     The new storm might also hit the Northeast, the nation's largest market for heating fuel. The weekend

blast largely bypassed that region.
