DISCUSSION AND OUTLOOK
At 400 PM CDT (2100 UTC), the center of Tropical Storm Barry was
located near latitude 30.1 North, longitude 92.3 West. Barry is

reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...
Intracoastal City to Shell Beach...3 to 6 ft
Shell Beach to Biloxi MS...3 to 5 ft
Lake Pontchartrain...3 to 5 ft
Biloxi MS to the Mississippi/Alabama border...2 to 4 ft
Lake Maurepas...1 to 3 ft
Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances. For
information specific to your area, please see products issued by
your local National Weather Service forecast office.
