| Episode narrativeepisode_narrative | The ninth named storm, fourth hurricane, and second major hurricane of the 2021 Atlantic hurricane season, Ida originated from a tropical wave in the Caribbean Sea on August 23rd. On August 26th, the wave developed into a tropical depression, which organized further and became Tropical Storm Ida later that day, near Grand Cayman. On a northwestward track, Ida intensified into a hurricane on August 27, just before moving over western Cuba. A day later, the hurricane underwent rapid intensification over the Gulf of Mexico as it passed over a warm core eddy and reached major hurricane strength. It was just under 72 hours from tropical depression formation to category 4 strength with 150 mph winds. Ida remained at its peak intensity of 150 mph winds and a minimum central pressure of 929 millibars as it made landfall near Port Fourchon midday on August 29th. It didn���t weaken to a tropical storm until it reached near the Louisiana/Mississippi border. ||Ida produced extensive to catastrophic damage across southeast Louisiana. On Grand Isle, around 40% of the structures were destroyed and the island was uninhabitable. Near 75% of the structures in Lafourche Parish were damaged or destroyed and likely similar numbers in Terrebonne Parish. 100+ mph wind gusts reached as far inland as Interstate 12. These winds damaged more than 30,000 poles, over 36,000 spans of wire and nearly 6,000 transformers. Of those more than 30,000 Louisiana poles, nearly 80% of those broken or damaged are from the most heavily impacted areas.|In total, the number of damaged or destroyed poles from Ida is more than hurricanes Katrina, Ike, Delta and Zeta combined. Due to major destruction to the power grid across the region, over 1 million customers were without power after landfall. Some of those power outages near the Louisiana coast lasted for around 4 weeks. |||The Louisiana Department of Health reported 3 direct fatalities and 28 indirect fatalities. Excessive heat and carbon monoxide poisoning were the most common causes of death. Indirect injuries associated with Ida: 351 heat-related, 183 carbon monoxide exposure, and 3 electrocutions. Storm surge ranged from a few feet to 10 to 15 feet. Hurricane Ida caused approximately $30 billion worth of damage. |
| Event narrativeevent_narrative | Storm surge flooding overtopped the White Ditch levee causing significant flooding along Hwy 39 from White Ditch to Braithwaite. The surge also overtopped the back levees along the west bank, flooding areas along Hwy 23 from West Point A La Hache through Myrtle Grove, Ironton and Alliance. Many homes in the area are elevated, but unelevated homes were pushed off of their foundations and others were flooded with several feet of water. Numerous cattle and horses were killed when they were trapped by the flood waters. |
