Hurricane Sandy Looks as 'Frankenstorm' Approaching U.S. East Coast

Oct. 26 at 1415 UTC (10:15 a.m. EDT) and shows Hurricane Sandy's huge =
cloud extent of up to 2,000 miles while centered over the Bahamas, and =

=E2=80=94 NASA's TRMM satellite revealed Hurricane Sandy's heavy =
rainfall and the storm is expected to couple with a powerful cold front =
and Arctic air to bring that heavy rainfall to the Mid-Atlantic and =
northeastern U.S. Some forecasters are calling this combination of =
weather factors "Frankenstorm" because of the close proximity to =
Halloween.
NASA satellites have provided forecasters at the National Hurricane =
Center with rainfall data, infrared, visible and other data on Sandy and =
will continue to do so. Dr. Marshall Shepherd who works with TRMM data =
provided an insight into the storm's development.
NASA's TRMM Satellite Sees Sandy Drench Jamaica and Eastern Cuba
The Tropical Rainfall Measuring Mission (TRMM) satellite had a partial =
view of hurricane Sandy on Oct. 25 at 1425 UTC (10:25 a.m. EDT) after it =
had passed over Cuba and moved into the Bahamas. An eye was hard to find =
but TRMM's Microwave Imager (TMI) data showed that a large area of =
intense rainfall was occurring around Sandy's center of circulation. Hal =
Pierce of NASA's TRMM Team at NASA's Goddard Space Flight Center in =
Greenbelt, Md. used a GOES-13 satellite image captured at the same time =
to fill in the part of the image not viewed by TRMM to create a total =
picture of the storm.
With its combination of passive microwave and active radar sensors, TRMM =
is ideally suited to measure rainfall from space. For increased =
coverage, TRMM can be used to calibrate rainfall estimates from other =
additional satellites. The TRMM-based, near-real time Multi-satellite =
Precipitation Analysis (TMPA) made at NASA Goddard can be used to =
rainfall over a wide portion of the globe. TMPA rainfall totals were =
tallied for the seven-day period from Oct. 18-25, 2012.The heaviest =
rainfall occurred over open ocean where totals were as high as 325 =
millimeters. Rainfall amounts as high as 250 millimeters were measured =
over eastern Cuba and some extreme southern areas of Hispaniola.
Hurricane Sandy passed over the islands of Jamaica and Cuba causing at =
least 21 deaths. Extensive flooding and other damage were reported near =
the capital city of Kingston and other areas of Jamaica.
National Hurricane Center Rainfall Expectations
The heavy rainfall potential is evident in the National Hurricane =
Center's (NHC) forecast on Oct. 26. The NHC noted that Sandy is expected =
to produce total rainfall amounts of 6 to 12 inches across Haiti and the =
Dominican Republic with isolated maximum totals of 20 inches possible. =
Rainfall totals of 3 to 6 inches are expected over portions of the =
Bahamas with isolated maximum amounts of 12 inches possible. Rainfall =
totals of one to three inches are expected across the Florida Keys into =
southeastern and east-central Florida with isolated maximum amounts of =
six inches possible. Rainfall totals of 4 to 8 inches are possible over =
far eastern North Carolina.
Interview with Research Meteorologist Dr. Marshall Shepherd
Dr. Marshall Shepherd, University of Georgia Professor and Research =
Meteorologist has worked with TRMM satellite data since its launch in =
1997. Dr. Shepherd provided his take on the storm event. "Models are =
coming into consensus on a landfall, if you will, in the DelMarVa area. =
Comparisons are being made to the Perfect Storm of 1991, but many folks =
won't remember that. Storm will bring very strong winds (hurricane =
force) over a strong area. Remember the Derecho of June 29, 2012. Expand =
that to the entire Delaware/Maryland/Virginia and New York/New Jersey =
region."
Shepherd said that the event will bring significant rains and inland =
freshwater flooding , that he said was often the deadliest threat from =
tropical systems. He also cited concerns about the storm surge and =
coastal flooding as full moon will mean elevated water levels/tides =
coupled with the storm-induced surge. Finally, he noted, there is likely =
to be heavy wet snow into the inland and higher elevations of the =
effected region. "Pay attention to the cone or area of influence rather =
than a specific track as the storm will affect an area not a point," he =
said.
"Advances from NASA satellites, aircraft, and models are essential for =
ingest into the models, assessing storm locations and intensity, and =
testing future modeling techniques. It may not be obvious to many, but =
our warning and prediction capability does have traceability to the NASA =
program in numerous ways and I have been happy to play some small role =
as a former NASA scientist and current member of the NASA Precipitation =
Science Team and Earth Science Subcommittee of the NASA Advisory =
Council."
Where is Sandy on Friday, Oct. 26?
A Hurricane Warning is in effect for the Northwestern Bahamas Except =
Andros Island. A Tropical Storm Warning is in effect for the Central =
Bahamas, Florida East Coast from Ocean Reef to Flagler Beach, Lake =
Okeechobee and Andros Island in the northwestern Bahamas. A Tropical =
Storm Watch is in effect for Savannah River to Oregon Inlet North =
Carolina, Pamlico Sound, the Florida east coast from North of Flagler =
Beach to Fernandina Beach, the Florida Upper Keys from Ocean Reef to =
Craig Key, and Florida Bay.
On Friday, Oct. 26, at 8 a.m. EDT, Hurricane Sandy's maximum sustained =
winds were near 80- mph (130 kph). Sandy is a category one hurricane on =
the Saffir-Simpson Hurricane wind scale. Some weakening is possible =
during the next day or so, according to the National Hurricane Center. =
It was centered near latitude 26.4 north and longitude 76.9 west. Sandy =
is moving northwest near 10 mph (17 kph) and is expected to turn north =
and then northeast on Oct. 27, while slowing down.
Storm surge is expected to be big factor as Sandy approaches the =
Mid-Atlantic coast. Very rough surf and high and dangerous waves are =
expected to be coupled with the full moon. The National Hurricane Center =
noted that the combination of a dangerous storm surge and the tide will =
cause normally dry areas near the coast to be flooded by rising waters. =
The water could reach the following depths above ground if the peak =
surge occurs at the time of high tide. Some storm surge forecasts =
include: 5 to 8 feet in the hurricane warning area in the Bahamas and =
one to three feet along the Florida coast in the warning areas on Oct. =
26.
GOES-13 Satellite Shows Sandy and Powerful Cold Front
NOAA's GOES-13 satellite monitors weather over the eastern U.S. and the =
Atlantic Ocean. In a visible image taken from NOAA's GOES-13 satellite =
on Friday, Oct. 26 at 1415 UTC (10:15 a.m. EDT) Hurricane Sandy's huge =
cloud extent of up to 2,000 miles extended into the Atlantic, while its =
center was over the Bahamas. At the same time a long line of clouds =
associated with a powerful cold front approaching the U.S. east coast =
stretched from the upper Midwest to the Gulf coast. The image was =
created by the NASA GOES Project at NASA Goddard.
"Frankenstorm"
Hurricane Sandy is expected to mix with a powerful cold front =
approaching the east coast, and cold Arctic Air mass, setting up for a =
powerful storm, a "Frankenstorm."
The cold front stretching from the upper Midwest to the Gulf coast is =
moving eastward and is expected to temporarily push Sandy away from the =
coast. However, the front is expected to break down as it moves toward =
the coast, allowing Hurricane Sandy to come back toward the coast.
As happens when any storm becomes extra-tropical, Sandy will go from a =
warm to cold core center and the strongest winds spread out and the =
storm will expand. According to the National Hurricane Center, hurricane =
force winds extend outward up to 35 miles (55 km) from the center and =
tropical storm force winds extend outward up to 275 miles (445 km). The =
wind field of Sandy is expected to grow in size during the next couple =
of days. The storm's circulation almost reaches 2,000 miles.
Although landfall is expected in southeastern Delaware early Tuesday =
morning as a hurricane, the Mid-Atlantic is expected to start feeling =
the storm's effect starting Sunday, Oct. 28.
