Impact Based Warning: Severe Thunderstorms

15 January 2022

Hazard Alert Level Affected Municipalities Valid From (SAST) Valid To (SAST)
Severe Thunderstorms Yellow (L2) (High likelihood of Minor Impacts) Beaufort West, Hantam, Kannaland, Karoo Hoogland, Khâi-Ma, Laingsburg, Oudtshoorn, Prince Albert 15/01/22 11h00 15/01/22 22h00

Discussion: Showers and thundershowers are expected to develop over the interior of the Namakwa as well as the Central and Little Karoo from early afternoon, where some may become severe with quick and heavy downpours (30-40mm/hour) which can lead to flash flooding as well as possible large amounts of small hail (diameter of 2cm and less).

Impact: Localised flash flooding of susceptible roads, low-lying areas and bridges (main concern being the N1 and the Swartberg Pass) which can lead to difficult driving conditions especially where the roads are slippery due to the combination of hail and pooling of water on the roads and the heavy downpour that can reduce visibility. This may contribute to minor vehicle accidents and longer travel times. Localised damage to infrastructure and settlements (mainly informal) and localised and short term disruption to municipal and other essential services are also possible.

Instruction: If possible stay indoors away from metal objects. Do not seek shelter under trees or tall objects. Do not go fishing or play golf as both the golf clubs and fishing rods are good conductors of electricity. Be aware that any combination of hail, strong winds and/or heavy downpours can accompany the storms.
