Atmospheric River in the Pacific Northwest and Northern Rockies this Weekend

A Pacific storm and atmospheric river will impact the Pacific Northwest states and northern Rockies this weekend, bringing locally heavy low elevations rain and heavy high elevation snow in the mountains. By Sunday over the Interior Northwest, rain combined with snowmelt will increase the risk of flood hazards. Flood Watches are in effect. Read More >

Overview

At approximately 1:55 p.m. a tornado began around 6 miles east-southeast of the center of Trinidad along County Road 24.6. It moved east across a ranch, narrowly missing several buildings. A split rail fence was damaged along the driveway leading to the ranch buildings and many juniper tree branches were snapped off. A young man was caught in the circulation and suffered some bruises, due to flying dirt and rocks. He did not need to be treated at a medical facility. After that the tornado traveled over open country and stayed on the ground for around 35 minutes before dissipating. Shortly after, the storm powered up again and spawned another tornado that lasted around 5 minutes. It crossed US Highway 160 near County Road 101.8. At the widest the first tornado was around a 1/4 mile across. This is a LINK to a YouTube video provided by Jeffrey Sepulveda showing the first tornado over open country east of County Road 24.6. The preliminary rating of the tornados is high-end EF1, given the damage to wooden power poles and trees. The National Weather Service in Pueblo will have more information on this tornado as new information becomes available. Thanks go to Bill Gargan, senior forecaster at the National Weather Service in Topeka, KS for providing the information about there being two tornados east of Trinidad.
