UPDATE (12:15 p.m. PT) – The National Weather Service said two small tornadoes were spotted in the Portland metro area Sunday night.
After investigating damage at Plumper Pumpkin Patch & Tree Farm farm, the weather service on Monday ruled that a tornado had touched down there. TV station KGW shared images on social media that appeared to show a circular pattern of storm damage at the farm.
The Columbian reported that numerous witnesses saw the second twister, which touched down north of Vancouver around 8 p.m. Only minor damage has been confirmed.
Two tornado warnings came amidst torrential rains and hail that pelted the metro area Sunday evening. Each warning was lifted within about an hour.
Weather officials also issued a brief flood advisory Sunday night for southwest Washington amid reports of standing water on Interstate 5 in Vancouver. The agency measured a quarter-inch of rainfall in 15 minutes in Northeast Portland.
