Local Storm Reports (LSRs) — Tornado, Hail, Wind, Flood

Local Storm Reports (LSRs) — Tornado, Hail, Wind, FloodWhat spotters and the public report to NWS during severe weather, plus accuracy caveats for LSRs.Local Storm Reports (LSRs) are observations of severe weather as it happens — submitted by trained spotters, law enforcement, the public via Spotter Network and CoCoRaHS, and confirmed by the local NWS office. The dashboard pulls the last 48 hours of reports for a county and its surrounding counties.Common report types

Tornado: Confirmed tornado on the ground.

Funnel Cloud: Funnel observed but not in contact with the ground.

Wall Cloud: Lowering attached to a thunderstorm — possible tornado precursor.

Hail: Hail size reported, in inches (1.00" = quarter, 1.75" = golfball, 2.75" = baseball, 4"+ = softball).

Wind / Gust: Wind damage or measured gusts, in mph.

Flash Flood: Active flash flooding observed.

Heavy Rain: Significant rainfall amount reported.

Note on accuracyLSRs come in from many sources of varying training. Hail and wind reports especially can over- or under-estimate. NWS verifies and revises reports for the official storm log, which lags real-time by hours to days.Part of the BloomWX learn library — beginner-friendly explainers covering every surface of the BloomWX weather dashboard.
