USA - May 20th, 2012

A plume of smoke from a fire near Pensacola, Florida, rises upwards, creating a thick cloud, before blowing towards the northeast. Partially visible through the smoke is Pensacola Bay. Visible west of the fire is Mobile Bay, Alabama, and at the far left is part of the sediment-laden Mississippi Delta, in Lousiana. Visible to the east of the fire is Choctawhatchee Bay, and at the far right is the sediment-filled Apalachicola Bay, in Florida.

As of 3:00 PM CST (2100 UTC), the center of Tropical Storm Ida was located near latitude 28.4 north, longitude 88.5 west, or about 60 miles (95 km) southeast of the mouth of the Mississippi River and about 165 miles (265 km) south-southwest of Pensacola, Florida.

Ida is moving toward the north near 18 mph (30 km/hr). A reduction in forward speed is expected over Monday night. On the forecast track, the center of Ida should reach the northern gulf coast Monday night. After landfall, Ida is expected to turn eastward on Tuesday.

Maximum sustained winds are near 70 mph (110 km/hr) with higher gusts. Weakening is expected Monday evening as Ida moves over cooler waters prior to making landfall and is expected to merge with a frontal zone on Wednesday.

Tropical storm force winds extend outward up to 200 miles (325 km) from the center. The latest minimum central pressure reported was 991 mb (29.26 inches).

A tropical storm warning remains in effect from Grand Isle, Louisiana eastward to the Aucilla River, Florida, including New Orleans and Lake Pontchartrain, meaning that tropical storm conditions are expected somewhere within the warning area within 24 hours.

Rains from Ida are already moving across the coast within the warning area. Total storm accumulations of 3 to 6 inches, with isolated maximum storm totals of 8 inches, are possible through Wednesday evening from the central and eastern Gulf coast across the southeastern United States into the southern mid-atlantic states.

A dangerous storm tide will raise water levels by as much as 3 to 5 feet above ground level along the coast near and to the east of where the center makes landfall, as well as in areas of onshore flow in southeastern Louisiana. Near the coast, the surge will be accompanied by large and destructive waves.

Mobile and Perdido Bays, USA

Mobile Bay, Alabama, USA - June 2nd, 2009

Mobile Bay, Alabama, USA - June 2nd, 2009

Two bays can be seen draining into the Gulf of Mexico: Mobile Bay, in the center, and Perdido Bay, on the right. Here, the former is spilling a greater quantity of brown sediments into the gulf. On the left side of the image, several condensation trails are visible over land.

Mobile Bay is an inlet lying within the state of Alabama in the USA. Its mouth is formed by the Fort Morgan Peninsula on the eastern side and Dauphin Island, a barrier island, on the western side.

Mobile Bay is 413 square miles (1,070 km2) in area. It is 31 miles (50 km) long by a maximum width of 24 miles (39 km).

It is the fourth largest estuary in the United States, with a discharge of 62,000 cubic feet (1,800 m3) of water per second.

The deepest areas of the bay are located within the shipping channel, sometimes in excess of 75 feet (23 m) deep, but the average depth of the bay is 10 feet (3 m).

The Mobile River and Tensaw River empty into the northern end of the bay, making it an estuary. Several smaller rivers also empty into the bay: Dog River, Deer River, and Fowl River on the western side of the bay, and Fish River on the eastern side.

Perdido Bay is a bay draining the Perdido River that lies on the borders of Baldwin County, Alabama and Escambia County, Florida. It lies west of the Florida communities of Pensacola and Perdido Key and east of the Alabama communities of Orange Beach and Lillian.

Ono Island and the mouth of the bay are within Alabama territory, as the Florida border crosses the barrier islands just east of Perdido Pass and Alabama Point, where the bay empties into the Gulf of Mexico.
