Strong storm off the Pacific Northwest coast
* GOES-16 data posted on this page are preliminary, non-operational and are undergoing testing *
Nighttime images of Suomi NPP VIIRS Day/Night Band (0.7 µm) and Infrared Window (11.45 µm) data (above) showed an occluded extratropical cyclone off the coast of the Pacific Northwest at 1050 UTC or 3:50 AM local time on 13 November 2017. This system was producing storm force winds offshore.A GOES-16 Mesoscale Sector had been positioned over that region, providing imagery at 1-minute intervals — the structure and evolution of the storm could be seen using Lower-level (7.3 µm), Mid-level (6.9 µm) and Upper-level (6.2 µm) Water Vapor imagery (below).
