The South African Weather Service has placed north-eastern Limpopo on high alert ahead of Tuesday's forecast, with a Yellow Level 2 warning in effect for severe thunderstorm conditions. Residents in the affected areas face the prospect of heavy downpours, damaging winds, hail and frequent lightning strikes, which could trigger localised flooding and pose risks to property and communities.
Under the weather service's colour-coded warning framework, a yellow alert indicates a moderate threat requiring awareness and caution, while an orange warning represents a more serious risk demanding greater preparedness. The numerical levels assigned to warnings reflect the probability of adverse impacts, with Levels 2 and 6 indicating a higher likelihood and Level 4 pointing to a reduced chance of severe consequences.
