This is the kind of thing many people went through. They were in their homes and as the water got worse and worse, they became cut off from being able to walk away - so they were entirely at the mercy of their home’s foundation. If it gave way, it became an urgent emergency. Luckily this person had a life jacket and was able to get clear and get to land. I think many did not end up so fortunate. And I’m sure in many cases it happened more quickly and violently than this video. And at night.
I’m pretty sure this is what happened to the guy from Mandeville that died - I also just learned that he was roommates with one of my best friends (groomsman in my wedding).
