Track of TS 13L

The center of Tropical Storm Lee is located near 29.4 north, longitude 92.1 west. Lee is drifting erratically toward the north near 4 mph (6 km/h).

A slow and possibly erratic motion toward the north or north-northwest is expected during the next 24 hours, followed by a turn toward the northeast.

On the forecast track, the center of Lee is expected to cross the Louisiana coast later this afternoon or evening, then move slowly across southern Louisiana on Sunday.

Maximum sustained winds remain near 60 mph (95 km/h) with higher gusts. Some fluctuations in strength are possible this afternoon and tonight, with gradual weakening forecast to occur by Sunday afternoon.

Tropical-storm-force winds extend outward up to 230 miles (370 km) from the center. An offshore oil rig south of Sabine pass recently reported a sustained wind of 50 mph (81 km/h) and a gust to 60 mph (90 km/h) at an elevation of 230 feet above the surface.Reports from offshore oil rigs and Louisiana State University coastal observing sites indicate the minimum central pressure is 989 mb (29.21 inches).

The tropical storm watch has been replaced with a tropical storm warning from the Alabama/Florida border eastward to Destin, Florida. A tropical storm warning is also in effect from Destin, Florida westward to Sabine Pass, Texas, including the city of New Orleans, Lake Pontchartrain and Lake Maurepas.

Hazards affecting land include rainfall, stormsurge, wind and tornadoes. Tropical Storm Lee is expected to produce total rain accumulations of 10 to 15 inches from the central gulf coast northward into the Tennessee Valley, with possible isolated maximum amounts of 20 inches through Sunday. These rains are expected to cause extensive flooding and flash flooding. A storm surge will raise water levels by as much as 3 to 5 feet above ground level along the Louisiana coast, and by as much as 1 to 3 feet above ground level along the Mississippi and Alabama coasts including Mobile Bay.

With regards to wind, tropical storm conditions are expected to continue over portions of the warning area tonight into Sunday, and possibly into Monday.A few tornadoes will be possible through tonight over portions of southern Louisiana, southern Mississippi, southern Alabama and the far western Florida Panhandle.

USA - August 1st, 2011

This wide-swath ASAR image stretches along the southern shoreline of the United States of America along the Gulf of Mexico, from Louisiana (left), to Mississippi, to Alabama, to the Florida Panhandle (right, visible upon opening full image). New Orleans and part of the Mississippi River Delta arm, in Louisiana, can also be seen entering the image from the left edge.

Bodies of water of note in this image include Lake Pontchartrain, north of New Orleans, and Mobile Bay, an inlet of the Gulf of Mexico, lying within the state of Alabama. Its mouth is formed by the Fort Morgan Peninsula on the eastern side and Dauphin Island, a barrier island on the western side.

USA - April 13th, 2011

The Mississippi River, 3,779 km (2,348 mi) long, is the second longest river, after the Missouri, in the United States. Its triangular drainage area, covering about 40% of the country and including all or part of 31 states, is approximately 3,250,000 sq km (1,250,000 sq mi), the third largest in the world.

This image focuses on the central and lower parts of the river’s course, as it flows across Arkansas, Mississippi and Louisiana, and showing its mouth at the Gulf of Mexico.

Near the top of  this image, the Mississippi River enters a wide (64-113 km/40-70 mi), low valley that was once an embayment of the Gulf of Mexico. Sediment has filled this area, and through the centuries the river has extended its mouth to the present location 966 km (600 mi) downstream.

This ASAR image shows the Ross Barnett Reservoir, an impoundment of the Pearl River between Madison and Rankin Counties in the U.S. state of Mississippi.

The 33,000-acre (130 km2) lake serves as the state’s largest drinking water resource, and is managed by the Pearl River Valley Water Supply District. The lake features 105 miles (169 km) of shoreline impounded on the south by a 3.5-mile (5.6 km) man-made dam and spillway.

Visible as a white area to the southwest of the lake is the city of Jackson, the capital and the most populous city of Mississippi. The 2000 census recorded Jackson’s population at 184,256, but according to July 1, 2008 estimates, the city’s population was 173,861 and its five-county Jackson metropolitan area had a population of 628,817.
