Most of parts of the east coast is under-lock down as state agencies warned Hurricane Sandy would wreak-havoc as early as Monday evening with life-threatening flooding in many as areas as she is expected to make land fall in New Jersey.
On Sunday night an estimated 375,000 residents in low-lying areas were ordered to get out and go into shelters as the mother of all Sandy was marching towards New York, New Jersey and Connecticut. All transport services were suspended. Domestic and internationals flights were taken of schedules, schools were closed and n on essential government workers were told top stay home. New York stock exchange also would be closed.
For New Yorkers, Sandy is the second biggest nightmare after the 9/11 attacks. The estimated 10 million New Yorkers bracing for mother of all Hurricanes stampeded into super markets in search of emergency supplies. All super markets would pull down shutters by Monday until the hurricane all activities return to normal.
President Obama addressing a hastily arranged news conference at the FEMA headquarters said “My first message is to all people across the eastern seaboard, mid-Atlantic going north. You need to take this very seriously,”
FEMA administrators also urged new Yorkers to prepare for the worst.
Meanwhile The NASA said in a news release that hurricane Sandy is a Category 1 hurricane on Oct. 28, according to the National Hurricane Center. Sandy has drawn energy from a cold front to become a huge storm covering a large area of the eastern United States. NASA satellite imagery provided a look at Sandy’s 2,000-mile extent.
Hurricane Sandy’s reach has grown on satellite imagery, and during the morning of Oct. 28, the storm intensified as there was a large pressure drop. The atmospheric pressure dropped to 951 millibars during the morning of Oct. 28, an eyewall formed. When a storm’s atmospheric pressure drops by a large amount as Sandy has done, it’s a sign the storm is strengthening tremendously.
Sandy continues to merge with a cold front. The combination is expected to bring heavy rainfall and tropical-storm-force sustained winds for a couple of days to the mid-Atlantic and northeastern United States, and cause flooding, downed trees and power outages.
The National Hurricane Center warned early on Sunday, Oct. 28, that “Sandy expected to bring life-threatening storm surge flooding to the Mid-Atlantic coast including Long Island sound and New York Harbor, winds expected to be near hurricane force at landfall.” Storm surge in the Long Island sound is expected between 6 and 11 feet.
NASA and NOAA Satellite Imagery Reveal Sandy’s Super-Size
The MODIS (Moderate Resolution Imaging Spectroradiometer) instrument on NASA’s Terra satellite captured a visible image of Hurricane Sandy on Oct. 26 at 16:10 UTC (12:10 p.m. EDT). The image showed the massive extent of its clouds, covering about 2,000 miles. Sandy’s center was in the Bahamas at that time, and an eye was clearly visible. Sandy’s western clouds were brushing the southeastern U.S. coast during the time of the image.
NOAA’s GOES-13 satellite captured a visible image of Hurricane Sandy on Oct. 28 at 1302 UTC (9:02 a.m. EDT) that showed the massive extent of the storm, covering about one-third of the U.S. A line of clouds from the Gulf of Mexico stretching north into Sandy’s western circulation are associated with the cold front that Sandy is merging with. Sandy’s western cloud edge was already over the Mid-Atlantic and northeastern U.S.
This hybrid Sandy is also a super soaker. NASA’s Tropical Rainfall Measuring Mission (TRMM) satellite can measure rainfall from space. Oct. 27 at 1907 UTC (3:07 p.m. EDT), NASA’s TRMM satellite saw that rain associated with Hurricane Sandy storm’s center, was moderate and falling at a rate of 20 to 40 mm per hour (1.57 inches per hour). The heaviest rainfall at the time of the image was falling west of the center (and closest to the U.S. East Coast) at a rate of more than 2 inches (50 mm) per hour.
During the morning hours of Oct. 28, Sandy has been maintaining a small area of deep (strong) convection (rising air that forms the thunderstorms that make up the hurricane) near the center.
The National Hurricane Center has issued Flood Watches for the U.S. East coast and interior areas because Sandy is huge, slow moving and can drop up to 2 inches of rain per hour.
