GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) depicted the remnants of Hurricane Beryl, which was situated off the East Coast of the US on 13 July 2018. Note the presence of 2 apparent low-level circulation centers — the primary circulation became better exposed as areas of deep convection moved more quickly to the east.

Overlays of low-level (produced using Visible Band 2) and upper-level (produced using Water Vapor Band 8) Derived Motion Winds (below) highlighted the primary low-level circulation, as well as the trough aloft whose axis was located just to the west.

Contours of Deep-Layer Wind Shear from the CIMSS Tropical Cyclones site (below) revealed that there was a large gradient in shear over the region at 19 UTC, with higher shear northwest of the system — this verified the subjective appearance of high shear in that particular area, where low-level and upper-level Derived Motion Winds were nearly orthogonal.
