No, if you're smart, you have your hurricane kit prepared every June when the season starts. Water, non-perishable food, batteries, flashlights, etc. The state even gives you a tax-free week to buy supplies, including generators.
There are individuals who cannot evacuate, for many reasons. Or can't even get to shelters because they lack transportation. Was glad to hear local authorities were taking the homeless to shelters. I've never understood why those school buses couldn't be used to get those without transportation to shelters. The sight of school buses covered in water up to their roofs after Katrina was infuriating. They could have been used to get people out of the lower parishes.
