The post-tropical cyclone system was last addressed in a final advisory by the National Hurricane Center at 10 a.m. Sunday. Isaias weakened and had devolved from a Category 1 hurricane into a post-tropical cyclone with sustained winds of 25 mph. Isaias transited Tennessee and entered Kentucky. Post Tropical Cyclone Isaias is 180 miles northeast of Nashville Tennessee. Packing maximum sustained winds of 25 mph, it is tracking to the east-northeast at 22 mph.

“Little change in strength is forecast during the next 12 hours, with the low dissipating thereafter,” analysts explained.
