East Pacific Ocean Tropical Depression 1E intensified to become Tropical Storm Adrian (at 9.5º N latitude, 92.3º W longitude) at 03 UTC on 10 May 2017 — making it the earliest tropical storm on record in the East Pacific basin during the meteorological satellite era. GOES-16 Infrared Window (10.3 µm) images (above) revealed a series of nocturnal convective bursts which exhibited cloud-top infrared brightness temperatures in the -80º to -89º C range (shades of violet color enhancement).

During the subsequent daylight hours, GOES-16 Visible (0.64 µm) images (below) showed that southeasterly deep layer wind shear (source) had decoupled the organized convection from the exposed low-level circulation center (LLCC). Due to the far southern location of Adrian, only Full Disk scan images were available, at 15-minute intervals.

However, one of the GOES-16 Mesoscale Sectors was positioned over Adrian during the 2226-2355 UTC period, providing images of the LLCC at 1-minute intervals (below).
