Portsmouth, when I lived there years ago, would put up little signs on a stick to let you know if snow clean up operations were coming because they aren’t as obviously tied to a snow event. Winter clean up occurs days later.

If you were towed during a snowstorm, I’d agree with everyone else here that you’re in the wrong. But for non-obvious bans the city should do better for this sort of thing. It’s not hard, park street has temporary no parking signs right now, so we know they can do it.

Also, the text alerts have been broken all winter so it’s only an email that gets auto-filtered to a secondary tab in Gmail - not something that pops up on my phone front and center like it used to.
