Hourly GOES-West imagery from the CSPP Geosphere site, above (direct link to animation), shows the development of a broad Kona Low over the Hawai’ian islands. MIMIC Total Precipitable Water (TPW) fields over the eastern Pacific, below, show a very moist airmass moving into the eastern Hawai’ian islands as the Kona low develops to the west. The OSPO Percent of Normal fields at 1200... Read More
Metop-B and Metop-C both overflew Tropical Storm Mal as it approached the island of Fiji on 14 November. The toggle above shows the two wind plots from this website, MetopC from 0933 UTC and MetopB from 1013 UTC.
