On October 14, 2016, a rare tornado struck the city of Manzanita, Oregon. A powerful extratropical cyclone traversing the Pacific Ocean produced localized supercell thunderstorms along coastal Oregon. The Portland branch of the National Weather Service issued a record-breaking ten tornado warnings that morning for their forecast area. One particular cell spawned an EF2 tornado at 8:18 a.m. PDT (15:18 UTC) which traveled through the center of Manzanita. Although it lasted only two minutes, the tornado damaged 128 homes, rendered one uninhabitable, and downed one-third of the city's trees. No injuries or deaths were reported and damage reached $1 million. A state of emergency was declared for Manzanita immediately after the tornado; however, clean-up operations had to be delayed for two days as another storm system impacted the region. In the months following the tornado, approximately $70,000 was raised through various donations. Meteorological synopsis During the overnight hours of October 13–14, 2016, a powerful extratropical cyclone approached the Pacific Northwest. The Storm Prediction Center noted a low possibility for thunderstorms in association with this system as it neared the coast, and primarily focused on the large-scale damaging wind threat. Atmospheric instability only reached modest levels locally, represented by convective available potential energy (CAPE) values of 200–400 J/kg. Low-level wind shear reached values just supportive enough for tornadic development within low-topped thunderstorms developing along a cold front offshore. Subsequent enhancement of mid-level lapse rates from cold air aloft in combination with the aforementioned factors yielded a localized environment favorable to low-topped supercells along the immediate Oregon coast. Several potentially tornadic storms developed during the morning hours and impacted the state, prompting a flurry of tornado warnings by the Portland branch of the National Weather Service. Ten tornado warnings were issued that day, the most ever by the office in a 24-hour period and almost as many as the total number issued between 1986 and 2015. At 8:16 a.m. PDT (15:16 UTC), a warning was issued for Tillamook County for a rotating thunderstorm. Two minutes later, a waterspout moved ashore along Treasure Cove Lane in Manzanita. The tornado traveled approximately through the center of the city, reaching a maximum width of and causing extensive damage, before dissipating two minutes later near Highway 101. Peak winds in the tornado were estimated at 125–130 mph (205–215 km/h), ranking it as a high-end EF2 on the Enhanced Fujita Scale. The parent thunderstorm soon encountered a
