Six reports came in from Caldwell County. The first at 21:55 UTC near 5 SE Lenoir where a tractor-trailer overturned along Highway 321 at the Caldwell Community College and Technical Institute.

A tornado on the ground was reported by Hudson Fire Department at Redwood Park around 22:00 UTC. Four reports came in from 22:00 to 22:00 UTC from 4 SE Lenoir where a tree fell down on a car on Highway 321 at Mount Herman Road. Five homes were damaged around Fairwood Drive and Mount Herman Road, a steeple was blown off church at Starcross Road and Ellerwood Road. Numerous trees were downed.

At 03:00 UTC on October 9 (23:00 EDT, October 8), the center of Tropical Depression "Nate" was located about 115 km (70 miles) ENE of Nashville, Tennessee. Nate had maximum sustained winds of 55 km/h (35 mph) and was moving NNE at 32 km/h (20 mph) with minimum central pressure of 1 002 hPa.

Flash flood watches and flood warnings and advisories, as well as high wind warnings and advisories, are in effect across parts of the Southern and Central Appalachians. 

Doppler radar and satellite imagery indicate that the precipitation shield associated with Nate is on the northern and eastern side of the circulation as it continues to become more asymmetric. The highest rainfall rates are located in the Southern Appalachians and into Western Mid-Atlantic. Farther north across the Ohio Valley, tropical moisture is interacting with a frontal boundary, leading to moderate to heavy rainfall. 

Nate is expected to continue tracking northeastward, moving into eastern portions of the Ohio Valley states by Monday morning (local time) and into northeast Monday evening as a post-tropical cyclone.
