On Oct. 29, 2012 at 11 p.m. EDT, the center of Hurricane Sandy was just
10 miles (15 km) southwest of Philadelphia, Penn., near 39.8 North and
75.4 West. Sandy was still a hurricane with maximum sustained winds near
75 mph (120 kph) and moving northwest at 18 mph (30 kph). Sandy's
minimum central pressure had risen to 952 millibars. The
hurricane-force-winds extended 90 miles (150 km) east of the center of
circulation. Tropical-storm-force winds, however, went much further, as
far as 485 miles (780 km).
NASA's GOES Project created a "full-disk view" of NOAA's GOES satellite
data, that captured a global view of Hurricane Sandy's birth to
landfall. The animation of NOAA's GOES-13 and GOES-15 satellite
observations were combined from Oct. 21-30, 2012 and showed the birth of
Tropical Storm Sandy in the Caribbean Sea, the intensification and
movement of Sandy in the Atlantic Ocean along the U.S. East Coast, and

Sandy's Inland Movement on Oct. 29
At 2 a.m. EDT, on Oct. 29, Sandy's center was located just south of
Lancaster, Penn. At 5 a.m. EDT, Sandy continued moving to the
west-northwest at 15 knots (24 kph) and was located just 15 miles (24
km) east of York, Penn., and 90 miles (145 km) west of Philadelphia.
Sandy was centered near 40.5 North and 77.0 West. Sandy's minimum
central pressure continues to rise and was 960 millibars.
Sandy's sustained winds were near 65 mph. Tropical-storm-force winds
extend almost 1,000 miles. According to Weather Channel, the winds are
going to continue being a problem from the northeast into the Ohio
Valley today. The strongest winds are being experienced now in the Great
Hurricane Sandy has caused significant damage in New York City and along
the Mid-Atlantic coast. Flooding has been reported from Maine to Va.
During the morning hours on Oct. 29 (Eastern Daylight Time), nearly
eight million people were without power this morning up and down the
East coast. The Appalachian Mtns. received some heavy snow from western
Md. down to Tenn. and N.C. As much as 26 inches of snow had fallen in
Garrett County, Md. by the morning of Oct. 30. According to Reuters
news, flooding along the U.S. East Coast was extensive.
Watches and Warnings in Effect on Oct. 29
According to the NOAA's Hydrometeorological Prediction Center (NOAA/HPC),
there are high-wind warnings in effect including gale force winds over
the coastal waters of the Mid-Atlantic States, New York and New England.
Storm warnings are in effect for portions of the Mid-Atlantic coastal
waters. Flood and flash flood watches and warnings are in effect over
portions of the Mid-Atlantic and northeastern states.
NOAA's HPC forecast on Oct. 29 calls for Sandy to move in a
"west-northwest motion with reduced forward speed is expected today into
western Penn. with a turn north into western New York tonight, Oct. 30.
The cyclone will move into Canada on Wed., Oct. 31. Steady weakening is
forecast during the next 48 hours."
NOAA/HPC warns that gale-force winds will continue over parts of the
Mid-Atlantic through New England on Oct. 29 and storm surge and tides
can still cause normally dry areas along or near the coast to be
flooded, especially during high tide.
Rain and Snowfall Forecasts from NOAA
forecasts large rainfall totals for many areas in Sandy's reach. Far
northeastern N.C. could expect 3 to 6 inches, while 4 to 8 inches more
are possible over the Mid-Atlantic States on Oct. 30. Both areas can see
isolated higher totals. Between 1 and 3 inches are possible with up to 5
inches in the southern tier of New York state and northeastward through
Snowfall between 2 and 3 feet are expected in the W.Va. mountains with
higher totals through Oct. 30. Snowfall of 1 to 2 feet in the
southwestern Va. and Ky. Mountains are expected, and between 12 and 18
inches along the N.C. and Tenn. Border and in western Md.
