WATCH: Preparing for what can happen in the post-Katrina era
FEMA a 'national disgrace' in 2005
During Hurricane Katrina in 2005, it was clear the government failed to do all it could to prepare for the worst and react to the crisis.
More than 1,800 people died, 300,000 homes were destroyed and 60,000 needed rescue. In some parts of the Gulf Coast, the floodwaters were 20 feet deep.
The Federal Emergency Management Agency's (FEMA) response was dubbed a national disgrace -- relief took days to arrive, and people went without basic necessities like food and water.
Lessons learned in 2016?
But this time, those lessons learned from Katrina seem to have paid off. In the flooded neighborhoods surrounding Baton Rouge, there's a marked difference in FEMA's response.
More than 30,000 people have been rescued and more than 11,000 people are staying in temporary shelters. Even 500 pets have been rescued.
Social media played a role, making it easier to identify who needed help, and how.
