Extreme Weather Event Classification System

Extreme weather events (EWEs, read "ee-wee's") are organized into different categories called Classes. Classes represent the danger level of the event.

Classes

Classes are numbered, where a smaller number generally means an event is more dangerous to life, property, and/or the local space-time fabric. Class 0 (read as "Class Zero" or "Class Null" interchangeably) events are the most dangerous, representing extreme danger with little possible mitigation. Class 4 events are the least dangerous, representing little-to-no danger to life or property.

• Class 0: Extreme danger without known methods of protection or mitigation (especially where mere shelter may not be sufficient to survive)
• Class 1: Extreme danger requiring known methods of protection or mitigation. Survival is often not guaranteed, even if all measures are taken.
• Class 2: Serious danger that can be mostly or entirely mitigated/protected against with known methods of protection.
• Class 3: Highly dangerous, but requires little to no action for survival.
• Class 4: Not currently known to be dangerous to life or property.

Who classifies events?

When a new EWE is discovered, a panel of scientists known as dusologists ("disaster studiers") from around the globe convene in a safe location (often selected by the affected nation(s), if their governments are still intact) to discuss the severity of the event and research ways to help protect people, property, and reality. Dusologists also try to find ways to attempt to prevent the EWE from recurring (or from occuring as severely) if possible. Panels of dusologists are often comprised of doctors, physicists, chemists, reality philosophers, and many more disciplines.
