you are correct. I glanced fast at Tropical Tidbits, saw the IR image, and thought I read Tropical Depression Omar based off the advisory. It's a minimal storm.
Would be the second straight I storm from this cycle of names to be 1 and done. Isaias replaced Ike which was retired in 2008. They never got to the I storm in 2014, so this is its first iteration. Ike replaced Isidore after 2002.
