PlainHazard records what has happened, as NOAA and FEMA filed it. It does not predict what will happen to a place, and it is not advice.

Before you rely on a figure
- Not a warning service. For a storm now, follow the National Weather Service and local officials.
- Not a property assessment. A county's record and FEMA's rating describe the county. Flood zones for a parcel are on FEMA's flood maps; insurance and building decisions need a professional.
- As filed. The figures are those of the federal files, which have gaps, late entries and estimated damage. The methodology lists the known limits.
- Independent. PlainHazard is not affiliated with or endorsed by NOAA, FEMA or any agency.
