Something went wrong.
The National Weather Service said Saturday morning that Tropical Storm Barry is now Hurricane Barry, a category 1 storm, making its way onto land near Morgan City, Louisiana. The storm, with 75 MPH sustained winds and expected 90 MPH gusts, is also expected to bring far more rain than wind. Forecasters say two or more feet of rain is expected and rain will fall where flooding has previously been an issue, the NWS says. Inland flooding was a big concern.
Saturday the National Hurricane Center said it expects storm surge inundation along the coast of southern and Southeastern Louisiana, portions of Lake Pontchartrain, and portions of coastal Mississippi where a storm surge warning is in effect. Water levels have already begun to rise in these areas, the NHC said in its 10 a.m. forecast update, “with peak inundation expected to occur later today. The highest storm surge inundation is expected between Intracoastal City and Shell Beach
As of Friday evening, some four million people are under a tropical alert. The Weather Channel reported “disastrous” flooding is possible, per the National Hurricane Center’s alerts. New Orleans called for voluntary evacuations for people who live in areas outside the levees, asked residents to be indoors by 8 p.m., and shelter in place as the city suspended public transit. The Mississippi River is expected to crest at 17 feet in New Orleans on Saturday, though “levees protect up to 20 feet.”
Saturday morning, the US Army Corps of Engineers said, “Storm Surge Warning continues for Intracoastal City to Biloxi, and Lake Pontchartrain. Life-threatening inundation from rising water moving inland during the next 36 hours in indicated locations.”
Still, the flood gates along the Big Mud were closed.
At its 7 p.m. update, the NWS said Barry will bring a storm surge of up to six feet and 10 to 20 inches of rain.
There’s widespread concern about inland flooding and the surge of water that is the most serious. Storm surge is produced by water being pushed toward the shore by the force of the winds moving cyclonically around the storm. The impact on surge of the low pressure associated with intense storms is minimal in comparison to the water being forced toward the shore by the wind.

Storm Surge is the Greatest Threat to Life & Property in a Hurricane, NOAA Says
According to the National Oceanic and Atmospheric Administration, “along the coast, storm surge is often the greatest threat to life and property from a hurricane.”
NOAA says that “large death tolls have resulted from the rise of the ocean associated with many of the major hurricanes that have made landfall” with Hurricane Katrina in 2005 a prime example “of the damage and devastation that can be caused by surge.”
More than 1,500 people died during Katrina and, NOAA says, “many of those deaths occurred directly, or indirectly, as a result of storm surge.”
“Storm surge in Mandeville has advanced visibly in the few minutes I’ve been here.”
Friday Evening, Many Hours Before Landfall, The Waters Were Already Rising & Storm Surge Evident & By Late Night, Conditions Were Worsening. Saturday Morning, Surge Seen Across Coast
At just after 6 p.m. Friday, many hours before the storm was expected to make landfall, the water it’s bringing with it was already being felt.
“Is anyone remember that saying “good Lord willing and the Creek don’t rise”. well the Creek has risen. God-bless all those in South East and Gulf Louisiana God-bless us all. I love my family and my friends. 10 to 15″ of rain still to come and the storm surge will hit tomorrow.”
Also just after 6, this tweet about lake flooding, well in advance of the storm.
“FRIDAY 6:24pm — I’ll be tracking #TropicalStormBarry storm surge levels from my hotel window in Lafayette, Louisiana. Note the water levels!”
Not the best idea.
It was reported that at around 10 p.m., “storm surge intensified rapidly in Golden Meadows, LA.This forced the closure of Hwy 1 which runs to Grand Isle cutting off everyone below Golden Meadow who chose to ignore the Mandatory Evacuation.”
In some locations, particularly extreme south Louisiana, evacuations were mandatory, Plaquemines Parish being among them. .View image on Twitter
As the sun is about to rise, a view Saturday morning shows the steady and relentless surge.
The US Coast Guard Has Secured Its ‘Area of Responsibility’ Along the Gulf Coast as Now-Tropical Storm Barry Continues to Move Inland
The Coast Guard says its Eighth Coast Guard District staff are “pre-staging assets in safe and nearby locations to prepare to respond after Tropical Storm Barry makes landfall.”
Aircraft at stations in Houston, New Orleans and Mobile, Alabama are in place, its Shallow Water Response teams have deployed and pre-staged in Covington, Louisiana.

Another three teams have deployed and pre-staged in Shreveport. Its New Orleans-based mobile response teams are getting ready in Slidell, Louisiana and the Coast Guard has crews from Tactical Law Enforcement Team South and Marine Safety and Security Team Kings Bay on standby in Mobile. A Coast Guard Family Support Team has been established in Slidell to “facilitate lodging and needs of evacuated dependents.”
The Coast Guard says that given “hurricanes and tropical storms can be deadly’ its ability to do rescues “can be diminished or non-existent at the height of the storm,” so it advises people to “be prepared, stay informed, and heed storm warnings.”
