How dangerous are Astronomical Low Tide events in the U.S.?

NOAA's Storm Events Database has catalogued 445 astronomical low tide events across 24 states and territories between 2015 and 2025. The cumulative human toll is 1 fatalities and 1 injuries, and the financial footprint reaches $11.9M in combined property ($11.9M) and crop ($0) damage. On a per-fatality basis this places astronomical low tide events at a low severity tier relative to other tracked hazard types in the NOAA catalog.

Where this hazard actually strikes varies sharply by region. The three states absorbing the largest share of events are LA (209 events, 0 fatalities), TX (70 events, 0 fatalities), NJ (51 events, 0 fatalities), a pattern driven more by climatology than by any one state's vulnerability. At the other end, states such as ME, CT, AL report far fewer events, often reflecting hazard climatology rather than underreporting.

The annual record is uneven rather than steadily rising or falling. The peak year on record was 2025, logging 102 events and $2.0K in property damage in a single calendar year. The most recent year in the dataset is 2025 with 102 events recorded. Across the full 11-year window, annual event counts reflect natural year-to-year noise given how infrequently this hazard is recorded at all.

How to interpret this data

NOAA storm event data is filed by local National Weather Service forecast offices, so reporting intensity can vary by jurisdiction and should be interpreted alongside FEMA disaster declarations for a fuller picture.

For household and business preparedness, this state-and-year view should be paired with local-level FEMA National Risk Index ratings, flood-zone maps where applicable, and up-to-date NWS watch/warning information, population exposure and asset value matter as much as raw event frequency for estimating real-world risk.
