No active hail or wind alerts are posted for Connecticut, and there are no notable local severe events at this time. SPC’s latest mesoscale discussions focus severe hail and severe/damaging wind potential well west of CT, mainly from the south-central and central/southern Plains into the Ozarks, with the lower Great Lakes and Ohio Valley mentioned only as a lingering frontal zone focus for occasional thunderstorms rather than a direct CT threat.
Statewide maxima from SPC verified reports and NWS warnings, last 12 months. Tornado EF ratings are assigned by NWS survey teams after ground surveys and published in NOAA's final storm records.

How Connecticut compares nationally
Ranked by SPC verified storm reports (wind, hail, tornado) across all 50 states over the last 12 months. Severity-weighted index scores each report by hazard (tornado ×20, hail ×4, wind ×1) so a single derecho's flood of wind reports doesn't outweigh tornado outbreaks. Recalculated daily as of Sep 12, 2026.
