One more app while I'm at it ... this one downloads the current
Navigational Warnings (NOTMAR) issued by the CCG.
Download warnings issued in the previous day, week month or year. Download all warnings, or just the type you are interested in for the area you are interested in (eg. Military Exercises in the Straight of Georgia).
Hopefully it will not only let me know when WG is active, but also get me paying more attention to other warnings, which I am probably a bit lax about.
