Unknown		Natural Resources Canada
⚠️ content.usc_all_unknown — urgency, severity, and certainty all reported as Unknown — using Unknown as a default across all three fields limits alert interpretability.
⚠️ content.no_instruction_time — instruction does not say by when the protective action should be taken — no deadline and no immediately-class directive.
⚠️ content.no_description_explains_effects — description names the hazard but does not explain the effects it will have on people, property or infrastructure.
