Hurricane Sandy (18L) – October 31st, 2012

The remnants of Hurricane Sandy (18L) can be observed over the USA in this image, stretching from the south to the northeast to the midwest. Many states were impacted by the storms.

High winds and waves washed sand onto coastal roads in southeastern Florida. The storm left power outages across the region. North Carolina was spared from major damage through the late evening hours of October 28, though winds, rain, and inland snow could affect the state through October 30. Several highways were flooded, and a state of emergency was declared in 24 western counties due to snow and strong winds.

On October 29, snow was falling in parts of the state of Virginia. Virginia was awarded a federal disaster declaration. At Sandy’s peak, 200,000 customers were without power, and in Northern Virginia where most of the outages occurred 92,000 customers were still without power on 30 October; the local utility intended to restore full service by 1 November.

West Virginia was also declared a federal disaster area, due to abnormally heavy snowfall. In Kentucky, the most impacted area was the Eastern region of the state where as much as eight inches of snow fell as Sandy merged with a cold front.

In Maryland, at least 100 feet of a fishing pier at the beach resort of Ocean City was destroyed. Several bridges were closed, and I-68 in far western Maryland and northern West Virginia closed due to impassable roads from heavy snow. Multiple vehicles are stranded on the interstate and the National Guard was sent out to help. Workers in Howard County, Maryland tried to stop a sewage overflow caused by a power outage October 30. Raw sewage spilled at a rate of 2 million gallons per hour. It was unclear how much sewage had flowed into the Little Patuxent River.

In Delaware, which was also declared a federal disaster area, rainfall at Rehoboth Beach totaled 6.53 inches inches by early afternoon, with nearly 7 inches at Indian River Inlet and more than 4 inches in Dover and Bear. At 4 p.m., Delmarva Power reported on its website that more than 13,900 customers in Delaware and Maryland’s Eastern Shore had lost electric service as high winds brought down trees and power lines. Delaware Route 1 is now closed by flooding from Dewey Beach to Fenwick Island.

In New Jersey, a 50-foot piece of the Atlantic City Boardwalk washed away. Half the city of Hoboken is flooded. In the early morning of October 30, authorities in Bergen County, New Jersey, are evacuating residents after a berm overflowed and flooded several communities. Police Chief of Staff Jeanne Baratta says there are up to 5 feet of water in the streets of Moonachie and Little Ferry.

In Pennsylvania, several bridges and highways were closed, and more than 1.2 million were left without power as a result of the storm. Storm impacts in Upstate New York were much more limited than in New York City; there was some flooding and a few downed trees. Large portions of the Manhattan borough of New York City were without electricity. The East River over flowed its banks, flooding large sections of Lower Manhattan. Battery Park had a water surge of 13.88 ft. Seven subway tunnels under the East River were flooded as of October 30. Sea water flooded the Ground Zero construction site.

Over 385,000 customers in Massachusetts were without power as of the afternoon of October 29, and flooding of roadways and buildings was reported. In New Hampshire, over 200,000 customers were without power as of late Monday, October 29. In Rhode Island, over 100,000 customers lost power during the storm. In Ohio, on October 30, at least 247,000 in northeast Ohio were without power, mostly in the Cleveland area. In Michigan, more than 120,000 customers were without power at one point, but as of 9 p.m. Tuesday, only 45,000 are still without power. The National Weather Service said that waves up to 23 feet high were reported on southern Lake Huron.

High Destructive Potential of Hurricane Sandy (18L), Eastern USA – October 29th, 2012

Track of TS 18L

As of 5 p.m. EDT (2100 UTC) October 28, Hurricane Sandy is located within 20 nautical miles of 32.4°N 71.3°W, about 270 mi (435 km) east-southeast of Cape Hatteras, North Carolina and about 530 mi (850 km) south-southeast of New York City.

Maximum sustained winds are 65 knots (75 mph, 120 km/h), with stronger gusts. Minimum central pressure is 952 mbar (hPa; 28.11 InHg), and the system is moving northeast at 13 kt (15 mph, 24 km/h). Hurricane force winds extend up to 175 miles (280 km) from the center of Sandy, and tropical storm force winds up to 520 miles (835 km) from the center.

According to the Weather Channel, Hurricane Sandy appears destined to enter the history books as one of the most exceptional and potentially destructive storms to strike the Northeast in modern history.

Sandy, in terms of geographic size, is already the largest Atlantic hurricane of the past quarter-century. In a sign of how extraordinarily large Sandy is, a tropical storm warning is also in effect for Bermuda, while lakeshore flood warnings have been hoisted on parts of the Great Lakes including Chicago. The full extent of the storm is best observed in the full image.

Sandy has stayed close to the borderline between high-end tropical storm and low-end hurricane status, despite an impressively low central pressure. But despite the absence of sustained triple-digit winds, the huge breadth of Sandy’s circulation promises widespread disruption to life for tens of millions of Americans.

Sandy will produce its greatest impacts in the Northeast and the Mid-Atlantic Monday into Tuesday. A huge area of strong winds is blowing water toward the U.S. mainland. Already by Sunday evening, tides in some locations were 2 to 4 feet above normal from the Outer Banks of North Carolina north to eastern Long Island.

Sandy’s rain bands and gusty winds continue to expand across the Northeast. The heaviest rain was focused on the Mid-Atlantic as of late Sunday evening. Winds were gusting in excess of 40 mph in several locations along the Mid-Atlantic and Northeast coastline.

Numerous high wind warnings have been issued across the Northeast for Monday and Tuesday, along with a slew of flood watches and warnings both for storm-surge flooding at the coast and freshwater flooding from rainfall inland. Blizzard warnings have even been posted for the mountains of West Virginia. Tropical storm warnings are in effect for parts of the North Carolina coast. In addition, the National Hurricane Center is forecasting hurricane-force winds from the Maryland/Virginia border to Cape Cod.

Life-threatening storm surge flooding of over 10 feet will be possible in Long Island Sound, and surge up to 6 feet above ground level is expected for parts of coastal North Carolina if peak surge occurs at high tide. Many other East Coast locations can expect dangerous storm surge.

Massive Blizzard Dumps Snow Over Eastern USA

USA - December 20th, 2009

A massive winter storm that dumped record amounts of snow in the east of the US is now slowly making its way toward the north-east, still shutting airports and closing roads. In Washington DC and New York airports have reopened and roads are being cleared, but authorities report it will be days before things return to normal.

The storm, which began with severe flooding and a tornado in Florida, has covered Washington DC, Philadelphia and New York with a blanket of snow smashing a 70-year-old records. The 33 centimetres of snow that fell in Washington, D.C., by late afternoon was the most ever recorded for a day in December.

The blizzard rocked the Mid-Atlantic and Northeast United States on Saturday, crippling travel across the region and causing hundreds of thousands of power outages. Five deaths appeared to have been caused by the storm system, which stretched from the Carolinas north to New England and spread into some Midwestern states.

Here, snow can be seen covering parts of New Jersey, Delaware, Maryland, Washington D.C., Virginia, West Virginia, North Carolina, South Carolina, Tennessee and Kentucky.

Forecasters said the storm system was expected to generate winds up to 55 km/h, which could cause near-whiteout conditions. Authorities in many areas asked drivers to stay off the roads if possible. The storm system, coming from the Gulf of Mexico and spreading out across much of the Atlantic coastline, was forecast to bring a mix of snow and freezing rain to North Carolina, Tennessee and parts of western and central Virginia.

Southern USA - June 2nd, 2009

Southern USA - June 2nd, 2009

The Southern United States constitutes a large distinctive region in the southeastern and south-central United States. As defined by the US Census Bureau, this region includes sixteen states and the District of Columbia.

The Census Bureau also defined three smaller units, or divisions: the South Atlantic States, the East South Central States and the West South Central States.

The South Atlantic States division comprises Florida, Georgia, North Carolina, South Carolina, Virginia, West Virginia, Maryland, Washington, D.C., and Delaware.

The East South Central States unit is composed of Alabama, Kentucky, Mississippi and Tennessee.

Finally, the West South Central States division includes Arkansas, Louisiana, Oklahoma, and Texas.

Biologically, the South is a vast, diverse region, having numerous climatic zones, including temperate, sub-tropical, tropical, and arid.

However, the South is generally regarded as being hot and humid, with long summers and short mild winters, being significantly warmer than the rest of the country. Many crops grow easily in its soils and can be grown without frost for at least six months of the year.

Several geographical features of note in this image are the the bayous and swampland of the Gulf Coast (bottom), especially in Louisiana, the Appalachian Mountains (running diagonally across from the center to the upper right), and the Mississippi River (flowing vertically parallel to the left edge).
