How does the South African Weather Service categorise severe weather warnings:
Severe weather is an extreme meteorological event or phenomenon, which represents a real hazard to human life and property and has the potential to cause damage, serious social disruption, or loss of human life.
Special Weather Advisory: an alert raising awareness up to five days in advance to either expected large scale potential disruptive weather systems that could later lead to specific watches/warnings with time, or to less urgent alerts of uncommon conditions.
Severe Weather Watch: an alert calling for preparedness to weather hazards that most likely will occur within one to three days and that could lead to disruptive and disastrous conditions.
Severe Weather Warning: an alert calling for reaction due to a very high certainty of a severe weather hazard that is already occurring or imminent within 24 hours and that could lead to disruptive and disastrous conditions.
