A level 9 weather warning is not a standard term used by the National Weather Service (NWS) in the United States. However, a level 9 orange warning was issued by the South African Weather Service for the Western Cape before heavy rain that moved over the country at the weekend. It is unclear what the specific criteria are for a level 9 warning in South Africa, as the NWS uses a different system of watches, warnings, and advisories. The NWS issues warnings for specific types of severe weather, such as tornadoes, severe thunderstorms, and winter storms, based on specific criteria such as wind speed, hail size, and snow accumulation. It is important to pay attention to any severe weather warnings issued by your local weather service and take appropriate precautions to stay safe.
