Published: July 16, 2019

The remnants of Barry will soak parts of the lower Mississippi and Ohio valleys into Tuesday evening, triggering more localized flash flooding in those regions.

Barry's remnant is currently centered over Illinois, but the torrential rain from it was focused on southern Arkansas much of Tuesday.

Water rescues and closed or washed-out roads were reported in northeastern Hempstead, Howard and central Nevada counties in Arkansas, where a flash flood emergency was previously in effect but has since been dropped.

A portion of Interstate 30 in Clark County, Arkansas, had to be closed because of the floodwaters, according to the state's Department of Transportation.

Doppler radar estimated rainfall totals up to 12 inches in southwestern Arkansas Tuesday morning.

The highest total from a rain gauge in the region is 13.50 inches in Murfreesboro, Arkansas, less than a half-inch shy of the state's tropical-cyclone rainfall record of 13.91 inches, set during Tropical Storm Allison in 1989.

Current Radar, Watches and Warnings

Damage from a possible tornado was reported Tuesday afternoon in Marshall County, Mississippi, where a trampoline was blown away and windows of a home were blown out, according to local media reports.

Flash flood watches have been issued by the National Weather Service from Arkansas into northern Mississippi, western Tennessee, western Kentucky, southeastern Missouri and southern Illinois.

Additional rainfall in these areas could trigger more flash flooding through Tuesday evening. Isolated rainfall totals up to 5 inches are possible in northern Mississippi.


Flash Flood Watches

Tropical moisture associated with Barry's remnants will move farther eastward on Wednesday, fueling showers and thunderstorms with torrential rainfall. Localized flash flooding is possible from the Tennessee Valley into the Northeast.

Barry Recap

Barry's origins were from a cluster of thunderstorms in the Plains around the Fourth of July, spawning an area of spin a few thousand feet above the ground, which eventually moved into the Gulf of Mexico to spawn Barry.

U.S. Air Force Reserve and NOAA Hurricane Hunter aircraft found sufficiently strong winds and just enough organization of thunderstorms around low pressure for the National Hurricane Center to deem this system a tropical storm Thursday morning, July 11.

Barry slowly gathered organization and strength to briefly become a hurricane on Saturday, July 13, just hours before landfall, becoming the first hurricane of the 2019 Atlantic hurricane season, but it weakened by early afternoon.

Barry made landfall early Saturday afternoon, July 13, along the Louisiana coast, according to the National Hurricane Center.

Rainfall

The heaviest rain on Monday fell from southwestern and central Louisiana into southwestern Mississippi. Doppler radar estimated that 10 to 15 inches of rain had fallen in parts of this zone, where significant flash flooding was reported Monday morning. Nearly 2 feet of rain was measured to the north of Lake Charles, Louisiana, near Ragley.

Some roads were closed midday Monday near Ville Platte, Louisiana, after vehicles became stranded in floodwaters, according to the National Weather Service.

A stretch of State Highway 83 was closed near Lydia, Louisiana, due to flooding Sunday.

In Jackson, Mississippi, a car was pulled from floodwaters early Sunday morning. One street in the city of Petal, Mississippi, was covered by 2 feet of water.

One day before becoming Barry, torrential rain soaked southeastern Louisiana Wednesday morning, July 10.

The National Weather Service issued a rare flash flood emergency for much of the New Orleans metro area that morning. Parts of the city picked up over 10 inches of rain in just a few hours, triggering widespread street flooding.

Storm Surge

The peak storm surge occurred along the south-central Louisiana coast near Barry's landfall around Vermillion Bay and the mouth of the Atchafalaya River.

A storm surge of around 7 feet was recorded midday Saturday, July 13, at Amerada Pass, while a 5- to 6-foot surge moved up the Atchafalaya River at Berwick, near Morgan City.

The river at Morgan City reached the 10-foot stage for only the second time in history. The only other times that happened was when the Morganza Spillway was activated to alleviate Mississippi River flooding in 1973 and 2011.

On the southern and western shores of Lake Pontchartrain, water levels were about 3 to 4 feet above normal at Lakeshore Park in New Orleans and about 4 to 5 feet above normal where the Bonnet Carre Floodway empties into the lake west of New Orleans, near LaPlace.

Streets on Dauphin Island, Alabama, were covered by 1- to 2-foot deep water and 2- to 3-foot deep sand from coastal flooding on Saturday, July 13.

Storm surge only produced a 1-foot rise on the Mississippi River at New Orleans. The river is expected to remain near a 17-foot stage, its highest level in more than eight years, but 3 feet below the 20-foot height of river levees.

Here the peak storm-surge values recorded by NOAA gauges, in feet above normal tide levels:

-Amerada Pass, Louisiana: 7 feet

-Berwick, Louisiana: 6.7 feet

-Bonnet Carre Floodway at Lake Pontchartrain (near LaPlace): 4.4 feet

-New Orleans (New Canal Station on Lake Pontchartrain): 3.5 feet

-Grand Isle, Louisiana: 3.1 feet

-Waveland, Mississippi: 3.1 feet

-Dauphin Island, Alabama: 2 feet

Winds

The strongest winds were generally east and south of the center of Barry near the Gulf Coast.

Multiple roofs were damaged on homes and businesses in Morgan City, Louisiana.

Video showed an airplane hangar blown over and rolled near Jeanerette, Louisiana.

Siding was torn off apartments in Lafayette, Louisiana, early Sunday morning, July 14, from winds estimated at 50 to 55 mph. Some trees and power lines were also downed in other parts of the city.

Due to soaked ground, wind gusts of 20 to 40 mph were sufficient to down numerous trees early Sunday morning, July 14, in Adams County, Mississippi, in the state's southwestern corner.

Here are the peak wind gusts measured during Barry, according to NOAA's Weather Prediction Center.

-Pinto Island, Alabama: 72 mph

-Cypremort Point, Louisiana: 67 mph

-Berwick, Louisiana: 63 mph

-New Iberia, Louisiana: 61 mph
