At 10 AM CDT (1500 UTC), the center of Tropical Storm Lee was located near latitude 29.9 north, longitude 91.9 west.  Lee is drifting toward the northeast near 3 mph (6 km/h).   This general motion is expected to continue today followed by a turn to the east-northeast tonight.  On the forecast track, the center will move slowly over southern Louisiana today and tonight.

Numerous offshore oil rigs also continue to report sustained tropical-storm-force winds a few hundred feet above the surface well to the southeast through southwest of the center.

A storm surge value of more than 4 feet recently occurred just south of Morgan City, Louisiana at Amerada Pass.

Recent reports from oil rigs and coastal monitoring stations indicate the minimum central pressure is 986 mb (29.12 inches).
