A series of Pacific fronts will bring periodic waves of showers and thunderstorms to parts of the Great Basin and Pacific Northwest the next few days. Swells, high surf, dangerous rip currents and areas of coastal flooding continue along much of the East Coast from both Humberto and Imelda.

Weedville Tornado

A tornado is confirmed to have touched down in Elk County on Tuesday May 4th just before 3 pm north-northwest of Weedville. Photo evidence shows tree damage concentrated along a narrow area along Old Byrnedale Rd and Route 255. Several trees were uprooted or snapped. This is likely near the end of the damage path based on weakening low level rotation and updraft strength observed by radar.

Video evidence from Weedville shows a rapidly rotating funnel approximately 0.5 miles west-southwest of route 255. A ridge line obstructed the view of the ground beneath the funnel. However, a radar-indicated tornado debris signature supports the idea that the tornado was likely on the ground and lofting debris at the time. That tornado debris signature can be seen below by the low Correlation Coefficient values co-located with the velocity signature on radar.

The path start and end points, path width and tornado strength are preliminary estimates and will be adjusted as necessary if new evidence of damage is found.
