Ah yes, the city's most useful page, hidden like a secret level in a video game nobody wants to play. You can usually grab those alerts as an RSS feed if the page has one, then run it through a free app like Feedly to get phone pings.

Yes! Finally someone who gets it. I did the exact same thing, sat on the fence for way too long while everyone kept saying "ah you don't need that down here" and then had one bad winter run that scared me straight.

Layering up works okay on short shallow stuff but once you're doing real deco in cold water it's just misery for no reason.
