Conclusion

There are many conclusions to take from this list, possibly the most important being that homeowner’s insurance for at-risk flooding homes is crucially important. However, it’s also important to remember that just because a hurricane is more widespread, that doesn’t necessarily mean it will be any more or less intense. The Louisiana Storms only impacted Louisiana, but still did billions of dollars worth of damage. No matter what, flooding can be damaging and deadly.
