As monitored here in NB on 15 MHz today (31 January), WWV ended the National Weather Service Atlantic and Pacific marine high-seas and storm warnings after 19:00 UTC. Before that time, announcements about the ending of the warnings were transmitted during minutes 4 and 7 after the hour with the Atlantic information in minutes 8 and 9 and the Pacific information in minute 10. So, the last storm warnings were during the 18:00 UTC hour. After 19:00 UTC, the announcements in minutes 4 and 7 were discontinued and the storm warnings in minutes 8, 9, and 10 were replaced with an announcement about the ending of the warnings. Presumably, there was a similar transition on WWVH.
