Living here in Florida, we see flooding perhaps a bit more than most folks. Though I'm not a huge fan of FEMA (I think they fall short in their preparation recommendations), they and NOAA have teamed up for National Flood Awareness Week (15-21 March). The information on their site does have good information for the uneducated or those just moving into a flood prone area as well as during and post flood info. Give it a look and double check your plan...we all sometimes miss a small detail that could have a big impact.
Be smart and stay safe!
