WDSU Chief Meteorologist Margaret Orr reviews 2021 hurricane season – New Orleans, Louisiana

New Orleans, Louisiana 2021-11-30 18:34:00 –

The numbers do not tell the story of Hurricane Season 2021. The forecast from NOAA projected 15-21 named storms, 7-10 hurricanes and 3-5 intense.The forecast was correct, but the devastation was unimaginable.There were 21 named storms, seven hurricanes and four major hurricanes. It was an active season. The third-most active season on record just behind last year and 2005. We got through all the names on the list from Ana to Wanda. It started earlier than the official start date of June 1 for the seventh year in a row. It had the earliest fifth named storm on record.But all we can think about is Ida. Ida was catastrophic. For the third time in the state’s history, a category 4 hurricane hit Louisiana. That means two years in a row we had a devastating Category 4 hit the state. Ida ties with Hurricane Laura from 2020 last year, and then you must go back 165 years to the Last Island hurricane of 1856 for another Category 4 hurricane with winds of 150 mph.Hurricane Ida made landfall at Port Fourchon at 11:55 a.m. Sunday Morning, Aug. 29, 2021, with 150 mph winds. It was the 16thanniversary of Katrina. Ida was stronger than Katrina.It more than knocked us down, it knocked a lot of us out.A total of 33 people died in Louisiana. Most were heat-related deaths after the hurricane, but carbon monoxide for the second year in a row was a big killer. An alligator attacked a man and killed him as he was wading in high water near Slidell.Storm surge was about 9-14 feet west of the Mississippi River and 8-12 feet east of the river. There was a 6-9 foot surge over the western portion of Lake Pontchartrain near Laplace. That strong easterly wind just pumped water into the lake and into Laplace. Many people were trapped in their attics and as many as 800 had to be rescued.There were 15 tornadoes. Some started as waterspouts along the Mississippi coast and then moved onshore. These tornadoes formed in rainbands wrapping around Ida. We were on the air nonstop with the warnings.Ida was a Category 4 at Port Fourchon where it made landfall. A nearby ship reported a wind gust of 172 mph. The anemometer at Grand Isle was blown out at 148 mph. About half of the buildings on Grand Isle were destroyed. Ten to 11 feet of water covered the western part of the island and 5-6 feet covered the eastern part of the island.Ida was still a category 4 at its second landfall near Montegut, and still a category 4 at Houma. Much of the circulation remained over the warm Gulf water and over the warm water of the Bayous, which helped maintain the strength of the hurricane.The pounding of the wind in the eyewall was disastrous. From the National Weather Service: There was widespread catastrophic structural damage across Lafourche and Terrebonne parishes. Many roads were impassable because of fallen trees. Both parishes were left with no power. Nearly every building in Leeville was destroyed. The storm surge in Lafitte sent 5-6 feet of water into many homes. Ida became a Category 3 when it jogged east across Lafourche moving near Raceland, Des Allemands, Bayou Gauche, and then Luling in St. Charles Parish. It then turned west putting Laplace in the strong winds of the eastern eyewall. Numerous buildings collapsed or suffered major damage. Nearly every road was impassable, and I-10 was covered with storm surge.Ida diminished to a category 2 as it moved into Livingston parish, and then a category 1 as it moved into St. Helena Parish wreaking havoc all along the way.Ida impacted all Southeast Louisiana, the Mississippi coast and Southwest Mississippi. The worst damage was on the South Shore where there was major wind damage, storm surge, flooding rains and catastrophic power outages with the failure of nine transmission lines.Twenty-two barges broke loose in Chalmette. Storm surge flooded Delacroix, Yscloskey, Shell Beach and Hopedale with up to 6-8 feet of water.When Ida moved north parallel to Tangipahoa Parish, it caused major wind damage across Tangipahoa and St. Tammany parishes, downing thousands of trees, making roads impassable, and causing widespread damage to homes. Heavy rain and storm surge caused flooding.I knew Hurricane Ida was going to be bad. It was, and still is for many. It is a long road to recovery. With such profound devastation on top of COVID-19, it’s sometimes hard to see the light at the end of the tunnel.Ida was not our only tropical impact. There was Claudette. It became Potential Tropical Cyclone 3 Thursday, June 17, at 3 p.m. about 475 miles south of Morgan City. Thankfully it had issues. Dry air and wind shear prevented the system from getting organized. It was still a potential tropical cyclone as it approached the Louisiana Coast Friday night. Coastal Flood Warnings were issued for the Mississippi coast for a 2-3 foot water rise. I was on the air Saturday morning with tornado warnings for the Mississippi Coast. A good 10 inches of rain fell in the Slidell area. It was not until 4 a.m. Saturday morning, June 19, that the National Hurricane Center officially named the system Claudette. Max winds were 45 mph. It quickly moved northeast and dissipated.We also had to deal with Nicholas, who was a slow mover and a rainmaker. Nicholas made landfall along the Texas Coast at Matagorda Peninsula, Tuesday, Sept. 14, as a hurricane. It then slowly moved east toward South-Central Louisiana, put on the brakes, became a remnant low, and then slowly moved north where it dissipated over Central Louisiana. Nicholas did not even move into Southeast Louisiana, but the problem with slow movers is that they dump a lot of rain. We were also on the east side. Baton Rouge got 9.24 inches of rain, Covington 5.65 inches, New Orleans 5.03 inches, and Slidell 4.26 inches. All of that rain fell just a couple of weeks after Ida. It was just too much.I have always said, at least you can see a hurricane coming. There’s time to get out of the way and rebuild another day. Thanks to climate change, things are changing. We have got to rebuild differently. The number of hurricanes is increasing, and the intensity is increasing. There was a category 4 hurricane in 1856, and then over 100 years later two category 4s in consecutive years: Laura and Ida. Louisiana was in the cone eight times last year and had four landfalls. We have got to rebuild stronger and wiser, and truly question how your property will hold up to another category 4 hurricane, because unfortunately there will be more.

The numbers do not tell the story of Hurricane Season 2021.

The forecast from NOAA projected 15-21 named storms, 7-10 hurricanes and 3-5 intense.

The forecast was correct, but the devastation was unimaginable.

There were 21 named storms, seven hurricanes and four major hurricanes. It was an active season. The third-most active season on record just behind last year and 2005. We got through all the names on the list from Ana to Wanda.

It started earlier than the official start date of June 1 for the seventh year in a row.

It had the earliest fifth named storm on record.

But all we can think about is Ida.

Ida was catastrophic. For the third time in the state’s history, a category 4 hurricane hit Louisiana.

That means two years in a row we had a devastating Category 4 hit the state.

Ida ties with Hurricane Laura from 2020 last year, and then you must go back 165 years to the Last Island hurricane of 1856 for another Category 4 hurricane with winds of 150 mph.

It more than knocked us down, it knocked a lot of us out.

A total of 33 people died in Louisiana. Most were heat-related deaths after the hurricane, but carbon monoxide for the second year in a row was a big killer. An alligator attacked a man and killed him as he was wading in high water near Slidell.

Storm surge was about 9-14 feet west of the Mississippi River and 8-12 feet east of the river. There was a 6-9 foot surge over the western portion of Lake Pontchartrain near Laplace.

Ida was still a category 4 at its second landfall near Montegut, and still a category 4 at Houma. Much of the circulation remained over the warm Gulf water and over the warm water of the Bayous, which helped maintain the strength of the hurricane.

The pounding of the wind in the eyewall was disastrous.

Ida impacted all Southeast Louisiana, the Mississippi coast and Southwest Mississippi. The worst damage was on the South Shore where there was major wind damage, storm surge, flooding rains and catastrophic power outages with the failure of nine transmission lines.

Twenty-two barges broke loose in Chalmette.

Storm surge flooded Delacroix, Yscloskey, Shell Beach and Hopedale with up to 6-8 feet of water.

hurricane ida

When Ida moved north parallel to Tangipahoa Parish, it caused major wind damage across Tangipahoa and St. Tammany parishes, downing thousands of trees, making roads impassable, and causing widespread damage to homes. Heavy rain and storm surge caused flooding.

I knew Hurricane Ida was going to be bad. It was, and still is for many. It is a long road to recovery. With such profound devastation on top of COVID-19, it’s sometimes hard to see the light at the end of the tunnel.

Ida was not our only tropical impact. There was Claudette. It became Potential Tropical Cyclone 3 Thursday, June 17, at 3 p.m. about 475 miles south of Morgan City.

Thankfully it had issues. Dry air and wind shear prevented the system from getting organized.

It was still a potential tropical cyclone as it approached the Louisiana Coast Friday night. Coastal Flood Warnings were issued for the Mississippi coast for a 2-3 foot water rise. I was on the air Saturday morning with tornado warnings for the Mississippi Coast.

A good 10 inches of rain fell in the Slidell area. It was not until 4 a.m. Saturday morning, June 19, that the National Hurricane Center officially named the system Claudette.

Max winds were 45 mph. It quickly moved northeast and dissipated.

We also had to deal with Nicholas, who was a slow mover and a rainmaker. Nicholas made landfall along the Texas Coast at Matagorda Peninsula, Tuesday, Sept. 14, as a hurricane.

It then slowly moved east toward South-Central Louisiana, put on the brakes, became a remnant low, and then slowly moved north where it dissipated over Central Louisiana. Nicholas did not even move into Southeast Louisiana, but the problem with slow movers is that they dump a lot of rain.

We were also on the east side. Baton Rouge got 9.24 inches of rain, Covington 5.65 inches, New Orleans 5.03 inches, and Slidell 4.26 inches.

All of that rain fell just a couple of weeks after Ida. It was just too much.

I have always said, at least you can see a hurricane coming. There’s time to get out of the way and rebuild another day.

Thanks to climate change, things are changing. We have got to rebuild differently. The number of hurricanes is increasing, and the intensity is increasing.

There was a category 4 hurricane in 1856, and then over 100 years later two category 4s in consecutive years: Laura and Ida. Louisiana was in the cone eight times last year and had four landfalls.

We have got to rebuild stronger and wiser, and truly question how your property will hold up to another category 4 hurricane, because unfortunately there will be more.
