[SatNews] SEVENTH UPDATE—On October 29, 2012, Hurricane Sandy approached the densely populated U.S. East Coast.
An estimated 60 million Americans were expected to be affected by rain, wind, snow, or ocean storm surges from the storm. The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite acquired this natural-color image of the storm at 1:35 p.m. Eastern Daylight Time (17:35 Universal Time) on October 29.
At 2:00 p.m. Eastern Daylight Time on October 29, the U.S. National Hurricane Center (NHC) reported that Hurricane Sandy was located about 110 miles (180 kilometers) southeast of Atlantic City, New Jersey, and about 175 miles (285 kilometers) south-southeast of New York City. The storm had maximum sustained winds of 90 miles (150 kilometers) per hour. The storm was moving toward the northwest at about 28 miles (44 kilometers) per hour. The NHC stated that Sandy could change into a wintertime low-pressure system later in the day, but cautioned that this would not weaken the storm prior to landfall.
The NHC forecast that Hurricane Sandy would come ashore on the evening of October 29, along the coast of southern New Jersey or Delaware. The NHC warned of multiple hazards associated with the storm. Hurricane-force winds were predicted for the Mid-Atlantic States, including New York City, with tropical storm-force winds from Virginia to Canada. A storm surge, combined with astronomically high tides (at full Moon), promised to flood coastal areas with waters as much as 11 feet (3 meters) above normal. Sandy was forecast to drop as much as 8 inches (20 centimeters) of rain, and the mountains of Appalachia were expected to receive up to 3 feet (1 meter) of snow.
The NHC urged potentially affected residents to consult their local National Weather Service forecast offices for more information. Government officials urged residents to heed evacuation warnings, and hundreds of thousands of people had fled their homes by October 29, CNN reported. More than 100,000 customers in seven states had already lost electrical power. In the days leading up to the storm, as residents stocked up on supplies and utility companies called in reinforcements from across the country, the U.S. Geological Survey deployed more than 150 storm-surge sensors along the Atlantic Coast to monitor Sandy’s effects in real time.
To witness Sandy’s tracking over the past three days, SatNews highly recommends the link below, which leads to the NOAA Environmental Visualization Laboratory website. The Real-Time GOES East Regions offers an animation of the images of the Northern Hemisphere captured by the GOES East satellite every 30 minutes and the entire Western Hemisphere every three hours. Simply follow the simple directions on the page to view the available imagery which reveal the extent, breadth and power of this super storm.

…Hurriance Sandy may be at 7:00 p.m. this evening, Monday, October 29th. The hurricane is expected to come ashore in central-south New Jersey. In the image below, the dark red indicates winds 50mph in the Washington DC area and purple winds 70 mph+ along the Jersey shore, Long Island and New York City area. It is also being reported by other media outlets that as many as 500,000 citizens are now with power, as of this writing.
Google.org‘s Crisis Response map reveals the project path of Hurricane Sandy as it comes ashore and initiates its treck to the northwest and then northwards. This map is available at this direct link to the Official google.org blog.
The Geostationary OperationalEnvironmental Satellite 13 (GOES-13) captured this natural-color image of…
…Hurricane Sandy at 1:45 p.m. Eastern Daylight Time (17:45 Universal Time) on October 28, 2012. Note how a line of clouds from a continental weather system runs south to north along the Appalachian Mountains, approaching from the west to meet the offshore storm.
Cameras on another geostationary satellite (GOES-14) collected “super rapid scan” images—one every minute from 7:15 a.m. until 6:26 p.m. EDT—which were compiled into a time-lapse video available on YouTube. In the animation, light from the changing angles of the Sun reveal the structure of the clouds and the details of the storm’s motion from dawn to dusk.
At 2:00 p.m. EDT, shortly after the still image above was acquired, the U.S. National Hurricane Center reported that Sandy was located at 32.8 degrees North and 71.9 degrees West, about 575 miles (930 kilometers) south of New York City. Maximum sustained winds were observed at 75 miles (120 kilometers) per hour, and the barometric pressure at the center of the storm was 951 millibars (28.08 inches).
The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite acquired this…
…natural-color image of Hurricane Sandy at 1:50 p.m. Eastern Daylight Time (17:50 Universal Time) on October 28, 2012. Suomi NPP was launched one year ago today.
Just moments after this image was acquired, the U.S. National Hurricane Center reported that Sandy’s center was located at 32.8 degrees North and 71.9 degrees West, about 575 miles (930 kilometers) south of New York City. Maximum sustained winds were observed at 75 miles (120 kilometers) per hour, and the barometric pressure at the center of the storm was 951 millibars (28.08 inches). The storm was predicted to make landfall in New Jersey on October 29, midway between Philadelphia and New York City.
UPDATE 2! — At noon, Eastern Daylight Time (16:00 Universal Time), on October 28, 2012, the…
…Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired the following image of Hurricane Sandy off the southeastern United States.
At 11:00 a.m. local time (one hour before the image was captured), the U.S. National Hurricane Center reported that the storm was located at 32.5 degrees North and 72.6 degrees° West, about 250 miles (400 kilometers) southeast of Cape Hatteras, North Carolina, and 575 miles (930 kilometers) south of New York City. Maximum sustained winds were 75 miles (120 kilometers) per hour, and the central pressure was 951 millibars (28.08 inches).
Forecasters predicted that the storm would continue heading north-northeast until the morning of October and then take a hard turn to the northwest into the coastaline of Delaware, New Jersey, or New York. The wind field from the storm was said to stretch 500 to 700 miles and was likely to affect an area from South Carolina to Maine, and as far inland as the Great Lakes. The storm has already caused significant damage in the Bahamas, Cuba, Jamaica, Puerto Rico, the Dominican Republic, and Haiti; at least 65 lives have been lost to the storm.
