Tornado and Wind Damage from Squall Line
January 21-22, 2010
A trough of low pressure oriented from W-E drifted south from northern Florida on Thursday 1/21 with a squall line developing over north Florida. Discrete cells developed south of this boundary in the mid afternoon and pushed quickly across east central Florida in the late afternoon and early evening hours of Thursday. Many of the cells exhibited rotation in the highly sheared environment, and a funnel cloud was observed near Ormond beach. No touchdowns were reported Thursday evening; however, wind damage occurred in Deland with strong thunderstorm gusts. Storm activity in east central Florida decreased during the mid-evening, but then additional storm development occurred during the pre-dawn hours of Friday 1/22 as the boundary sagged into east central Florida. Wind damage reports were received in the pre-dawn hours from near the Orange-Osceola county line into Brevard county where a tornado occurred shortly after sunrise.
