DISCUSSION AND OUTLOOK

----------------------

At 1000 AM CDT (1500 UTC), the center of Hurricane Barry was located

near latitude 29.6 North, longitude 92.0 West. Barry is moving

toward the northwest near 6 mph (9 km/h), and a turn toward the

north-northwest is expected tonight, followed by a turn toward the

north on Sunday. On the forecast track, the center of Barry will

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

Service station at Eugene Island, Louisiana recently reported

sustained winds of 62 mph and a wind gust of 82 mph.

The estimated minimum central pressure is 993 mb (29.33 inches).

HAZARDS AFFECTING LAND

----------------------

Key Messages for Barry can be found in the Tropical Cyclone

Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC.

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.

RAINFALL: Barry is expected to produce total rain accumulations of

10 to 20 inches over south-central and southeast Louisiana and

southwest Mississippi, with isolated maximum amounts of 25 inches.

Across the remainder of the Lower Mississippi Valley and western

portions of the Tennessee Valley, total rain accumulations of 4 to 8

inches are expected, with isolated maximum amounts of 12 inches.

This rainfall is expected to lead to dangerous, life threatening

flooding.

WIND: Hurricane conditions are occurring over a small area east of

the center and should persist for a few more hours. Hurricane

conditions are possible within the Hurricane Watch area today.

Tropical storm conditions are occurring across the Tropical Storm

Warning area to the east of the center at this time. Wind gusts

to tropical-storm force in squalls are possible along portions of

the coasts of Mississippi, Alabama, and the western Florida

Panhandle through tonight.

TORNADOES: A few tornadoes are possible through tonight across

the southeast Louisiana, southern Mississippi, and southern Alabama.
