move through southern Louisiana today, into central Louisiana
tonight, and into northern Louisiana on Sunday.
Maximum sustained winds are now near 75 mph (120 km/h) with higher
gusts. As it moves inland, Barry is forecast to weaken below
hurricane strength in the next few hours, and it is forecast to
weaken to a tropical depression on Sunday.
Hurricane-force winds extend outward up to 45 miles (75 km) to
the east of the center and tropical-storm-force winds extend outward
up to 175 miles (280 km) from the center. The National Ocean

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
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.
