The National Hurricane Center began issuing advisories on Tropical Depression 15 (located in the central Atlantic, east of Bermuda) on 11 October 2007. A GOES-12 visible image with ASCAT wind data sourced from the CIMSS Tropical Cyclones website (above) suggested that maximum winds were only around 30 knots.

There was strong southwesterly flow aloft over the developing cyclone with increasing deep layer wind shear, so the bulk of the deep convection was confined to the northeastern quadrant of TD #15 — an animation of GOES-12 visible images (below) shows that the low-level center was close to becoming exposed in that strong wind shear environment.
