Track of Irene

Although these images show Irene (09L) a few days ago while it was at hurricane strength, the system has since been downgraded to a tropical storm. Its center is currently nearing northern New England, USA, about 65 miles (100km) south of Rutland, Vermont.

This motion with a little faster forward speed is expected over the next
day or so. On the forecast track, the center of Irene will move over eastern Canada tonight and early Monday.

Maximum sustained winds have decreased to about 50 mph (85 km/h), with present movement towards the north-northeast (or 20 degrees) at 26 mph (43kph). Minimum central pressure is 975 mb (28.79 in).

A tropical storm warning is in effect for Cape Henlopen, Delaware northward to Eastport, Maine, including Delaware Bay, New York City, Long Island, Long Island Sound, coastal Connecticut and Rhode Island, Block Island, Marthas Vineyard and Nantucket. This warning also applies to the United States/Canada border northeastward to Fort Lawrence, including Grand Manan, and the south coast of Nova Scotia from Fort Lawrence to Porters Lake. Interests elsewhere in eastern Canada should monitor the progress of
Irene.

Hazards affecting land include storm surge, rainfall and wind. Elevated water levels will persist in areas of onshore winds along the coast from Connecticut through Maine. The highest water levels will occur near the upper parts of bays and inlets. Near the coast, these elevated water levels will also be accompanied by large, destructive and life-threatening waves. Higher than normal astronomical tides are occurring this weekend. Coastal and river flooding will be highest around the time of high tide.

Irene is expected to produce total rainfall accumulations of 4 to 6 inches, with isolated maximum amounts of 8 inches, from northeastern New York State northeastward through the northern portion of New England. These rains, combined with heavy rains over the past few weeks, could cause widespread flooding and life-threatening flash floods.

Tropical storm force winds will spread northward into portions of New Brunswick and Nova Scotia later today. Significantly higher wind speeds are likely over areas of elevated terrain in northern New England and eastern Canada.

Sediments in Bay of Fundy and Snow Across Parts of Canada and the USA

Canada - March 30th, 2011

Parts of the northeastern USA, including states such as Maine, New Hamshire and Vermont, and parts of the Canadian provinces of New Brunswick, Prince Edward Island and Quebec, are dusted with snow in this early spring image.

Other areas, such as Massachusetts, Connecticut and Rhode Island, and most of the Canadian province of Nova Scotia, are snow-free. Sediments can be seen along the coastline between Nova Scotia and Massachusetts, although most are concentrated in the Bay of Fundy to the north.

Canada - March 5th, 2010

Lake Champlain (center) is a natural, freshwater lake in North America, located mainly within the borders of the United States (states of Vermont and New York) but partially situated across the Canada-US border in the Canadian province of Quebec. Here, part of it is frozen, causing the southern half to appear dark blue while the upper half appears bluish-grey.

Although it is smaller than the nearby Great Lakes, Lake Champlain is a large body of fresh water. Approximately 1,130 km2 (440 sq mi) in area, the lake is roughly 180 km (110 mi) long, and 19 km (12 mi) across at its widest point. The maximum depth is approximately 400 feet (120 m). The lake varies seasonally from about 95 to 100 ft (29 to 30 m) above mean sea level.

Lake Champlain is situated in the Lake Champlain Valley between the Green Mountains of Vermont and the Adirondack Mountains of New York, drained northward by the 106 miles (171 km) long Richelieu River into the St. Lawrence River (seen flowing across the upper portion of the image) at Sorel-Tracy, Quebec, northeast and downstream of Montreal.

Northeastern USA and Southeastern Canada - April 13th, 2009

Northeastern USA and Southeastern Canada - April 13th, 2009

Southeastern Canada remains dusted with snow while the northeastern United States are snow free in this spring image.

Lake Ontario and its nearby Finger Lakes are visible left of the center, while the eastern tip of Lake Huron is visible on the edge of the image.

Moving over to the coast, the hook-shaped Cape Cod area in Massachusetts, USA is visible at the far right. To the south, Long Island is situated just off the coast, with New York City at its western tip.

Between Lake Ontario and Cape Cod, to the North, is Lake Champlain, a natural, freshwater lake located mainly within the states of Vermont and New York, USA, but partially situated across the US-Canada border in the Canadian province of Quebec.

East of Lake Champlain, a white trail runs North to South. This is the snow-capped peaks of the Green Mountains, in Vermont. The range, which is part of the Appalachian Mountains, extends approximately 400 km (250 mi) and has five peaks over 4,000 feet.

Snowfall over New England, USA - March 4th, 2009

Snowfall over New England, USA - March 4th, 2009

A huge snowstorm that hit the east coast of the USA a few days ago, covering states from Arkansas to Georgia and all the way up the coast to Maine.

A previous article examined the white swath coating the southeastern and mid-atlantic states. This image, on the other hand, focuses on the New England area, including the states of (from South to North) Connecticut, Rhode Island, Massachusetts, Vermont, New Hampshire and Maine.

Continuing northward, parts of Nova Scotia (center), New Brunswick (peninsula) and Quebec are also  snowcovered. Parts of the Saint Lawrence River (top left) are iced over.

Offshore, from the hook of Massachusetts’ Cape Cod Bay to Halifax in Nova Scotia, clouds form streaked patterns in the atmosphere.
