How dangerous are Marine Tropical Storm events in the U.S.?
NOAA's Storm Events Database has catalogued 650 marine tropical storm events across 2 states and territories between 2015 and 2025. The cumulative human toll is 49 fatalities and 0 injuries, and the financial footprint reaches $0 in combined property ($0) and crop ($0) damage. On a per-fatality basis this places marine tropical storm events at a high severity tier relative to other tracked hazard types in the NOAA catalog.
Geographic exposure skews toward a small cluster of frequently-hit states. The three states absorbing the largest share of events are GU (358 events, 49 fatalities), AT (292 events, 0 fatalities), a mix of underlying hazard climatology and how many people live in the exposed corridor.
Annual totals swing noticeably from year to year. The peak year on record was 2020, logging 153 events and $0 in property damage in a single calendar year. The most recent year in the dataset is 2025 with 36 events recorded. Across the full 10-year window, annual event counts reflect seasonal climate cycles and, for some years, longer climate-driven shifts in frequency.
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.
