Note that two the storms you're referring to (Iselle and Julio) may have similar predicted paths, but they currently 1000 miles away from each other, and will definitely not merge. Iselle is already impacting Hawaii, while Julio will not approach for several days (assuming the current forecast verifies).
Both FTDNA and Ancestry sponsor groups or projects where people in the same haplogroup can exchange information and maybe even find an ancient connection. But Y-DNA and mtDNA are intended to check ancient bloodlines, 10,000-50,000 or so years ago. They are not generally useful by themselves for genealogy.

It is defined by the 12f2.1 genetic marker, or the equivalent M304 marker.Haplogroup J is believed to have arisen 31,700 years ago (plus or minus 12,800 years) in the Near East (Semino et al. 2004).It is most closely related to Haplogroup I, as both Haplogroup I and Haplogroup J are descendants of Haplogroup IJ (S2, S22).Haplogroup IJ is in turn derived from Haplogroup F.92,110 pages on this wiki.
