As Hurricane Ida hits landfall in the Gulf region, the storm has already had devastating effects in New Orleans, NBC News reports. As of Monday morning, the tropical storm knocked out power for 1 million residents and businesses in New Orleans and throughout Louisiana.

According to the National Hurricane Center, the severity of the stark weather has had a disastrous impact.

In an effort to help vulnerable residents who may be displaced by the storm, some shared addresses for either their homes or those of others who'd been hit by Ida. 

One person said a family of eight saw a collapsed roof because of the storm.

Another struggled with getting in contact with their family. 

The heart-wrenching tweets called for aid for large families, grandparents with dementia and flooded homes. 

Hurricane Ida made landfall 16 years to the day that Hurricane Katrina hit, WDSU reported.

A Category 5 hurricane, Katrina caused over 1,800 deaths and $125 billion in damage in late August 2005, particularly in the city of New Orleans and the surrounding areas. The storm forever changed the landscape of New Orleans.

Although the two storms were eerily similar, there was no expectation of levees breaking with Ida. Because of the levees’ failures, Katrina's death expanded and its overall damage to about $176 billion in current dollars but experts don't expect Ida to come near those totals.

Brian McNoldy, University of Miami hurricane researcher described Katrina’s biggest issues as “man-made” and not just the result of the storm.

"This has the potential to be more of a natural disaster whereas the big issue in Katrina was more of a man-made one" because of levee failures,” McNoldy told CBS News.
