Tropical Depression Nine formed yesterday, Sept. 8 in the far eastern Atlantic, and NASA's Aqua satellite saw it strengthen into Tropical Storm Humberto today, Sept. 9 at 5 a.m. EDT. As that storm strengthened, the remnants of the once-tropical-storm Gabrielle continued to struggle near the Bahamas as NASA's HS3 mission investigated.
