A waterspout was reported just offshore WNW of Reedsport Oregon. It lasted around 5 minutes and remained offshore through its life. A member of the public took a picture and reported it to KOIN in Portland. From there WFO Portland heard about it and relayed the report to WFO MFR.

A line of thunderstorms was observed on radar and a Special Marine Warning was issued to address it. A wind gust to 43 mph was recorded at Port Orford when these thunderstorms moved onshore...so it is assumed that the warning criteria was met over the coastal waters.

This warning was based on radar and lightning observations. No verifying wind or hail observations were recorded, but given that Special Marine Warning criteria only requires an organized area of convection, a line of thunderstorms qualifies.

Thunderstorms developed over the coastal waters ahead of a cold front. This warning was based on satellite and lightning strike data. However, thunderstorms over the adjacent land mass later on produced large hail and gusts to 60 mph, so it is assumed that these storms produced g…

Based on radar returns, lightning data, satellite imagery, and coast based wind reports when the line moved onshore, it is assumed that this squall line was severe.

No marine reports were received, but a trained spotter 2N Coos Bay reported a gust to 71 mph at 13/1315 PDT when the squall line moved onshore. The Cape Arago sensor recorded a gust to 86 mph at 13/1300 PST, which was far above any other gust recorded that day. The sensor at Cape…
