Reports of tree damage with debris blocking portions of Dutch Neck Road and Thorntown Road northwest of Port Penn. Power outages also reported in the area. Time estimated.
A funnel cloud was observed near Port Penn. Photos showed it extended about halfway to the ground. This was likely a non-mesocyclonic funnel associated with interactions between new updrafts and old outflow boundaries. Time estimated from radar and public reports.
A downed tree and utility pole led to the closure of the intersection of West Market Street and Delaware City Port Penn Road. The time of the event was estimated from radar.
Thunderstorms with heavy rain caused flash flooding in Port Penn. Delaware State Route 9 was closed and several cars had to be abandoned. No serious injuries were reported.
