Steps
For bulk analysis, download the relevant year's Storm Events detail file from https://www.ncei.noaa.gov/pub/data/swdi/stormevents/csvfiles/, matching the naming pattern StormEvents_details-ftp_v1.0_d{YYYY}_c{creation-date}.csv
For interactive lookups, use the Storm Events Database search UI at ncei.noaa.gov/stormevents/choosedates.jsp, filtering by state FIPS code and date range
Parse event fields including event type, begin/end date-time, county/zone, magnitude (e.g., wind speed), and reported property/crop damage
Cross-reference wind/tornado/hurricane events against a service area and date range to identify storm-damage response windows
Consult the Storm-Data-Bulk-csv-Format.pdf documentation for the current column schema before parsing, since it can change between file vintages
Known gotchas
Data quality and reporting completeness vary significantly by era and location — academic reviews note known gaps and inconsistencies in the Storm Events Database, so treat it as indicative rather than authoritative for legal/insurance disputes
'Tree damage' is not a distinct queryable event category; it's embedded in free-text narratives or generic property-damage fields under wind/tornado/hurricane event types, so text parsing may be required to isolate tree-specific impacts
The dataset covers reported/observed severe weather, not a georeferenced point-level damage assessment — there's no lat/lon-radius query for 'storms near this address' in the base CSV/UI tooling
