At 4:50 pm, Barry continues to move inland over southern Louisiana but continues to lash the coast with dangerous storm surge, strong winds, and heavy rains. Here is the latest from the National Hurricane Center:
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 moving toward the north-northwest near 7 mph (11 km/h) and this general motion is expected to continue tonight. A turn toward the north is expected on Sunday. On the forecast track, the center of Barry will move across southern and southwestern Louisiana this evening, through central Louisiana tonight, and through northern Louisiana on Sunday.
Maximum sustained winds have decreased to near 65 mph (100 km/h) with higher gusts, and these winds are near the coast to the southeast of the center. Additional weakening is expected as the center moves farther inland, and Barry is forecast to weaken to a depression on Sunday.
Tropical-storm-force winds extend outward up to 175 miles (280 km) from the center. A United State Geological Survey station at Cypremort Point, Louisiana, recently reported sustained winds of 62 mph, while the National Ocean Service station at Eugene Island, Louisiana, reported sustained winds of 55 mph and a wind gust of 72 mph. In addition, the Acadiana Regional Airport in New Iberia, Louisiana, recently reported sustained winds of 45 mph and a wind gust of 61 mph.
The estimated minimum central pressure is 997 MB (29.44 inches).
HAZARDS AFFECTING LAND
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…1 to 3 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 Louisiana and southwest Mississippi, with isolated maximum amounts of 25 inches. Across the remainder of the Lower Mississippi 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: Tropical storm conditions are occurring across portions of the Tropical Storm Warning area, and these conditions should persist through Sunday morning. 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: Isolated tornadoes will be possible through tonight across southwest Alabama, southern Mississippi, and southeast Louisiana.
