A GOES-17 Infrared / Water Vapor Difference product (reference) from the CIMSS Tropical Cyclones site (below) highlighted areas of deep convection where overshooting tops were likely penetrating the tropopause (yellow to red enhancement).
GOES-17 Infrared images, with an overlay of deep-layer wind shear (below) indicated that Andres was approaching an environment of moderate to high shear, which would limit intensification.===== 10 May Update =====
