The South African Weather Service (SAWS) has warned of extremely high fire danger conditions in parts of five provinces on Thursday, 22 October.
The warning covers places in Limpopo, Free State, Northern Cape, North West and north-western KwaZulu-Natal.
Hot, dry and windy conditions can increase the risk of veld fires spreading rapidly, particularly in areas with dry grass and vegetation.
Which provinces are affected?
According to SAWS, extremely high fire danger conditions are expected in places over Limpopo, as well as parts of the Free State, Northern Cape and North West.
The warning also extends to north-western parts of KwaZulu-Natal.
However, this does not mean every town or district in the five provinces faces the same level of danger.
Why is the fire danger extremely high?
Several weather conditions can increase the risk of veld fires.
High temperatures can dry out vegetation, while low humidity reduces the amount of moisture in the air.
Strong winds can also cause fires to spread quickly, making them difficult to control.
When these conditions occur together, even a small fire can become dangerous.
The fire danger warning does not mean fires have already broken out.
Instead, it highlights weather conditions that could make fires easier to start and spread.
Why should residents take the warning seriously?
Veld fires can spread quickly across grassland, farmland and other areas with dry vegetation.
They can threaten homes, livestock, agricultural land and infrastructure.
Smoke from fires can also reduce visibility on roads and affect people with breathing difficulties.
SAWS has urged residents to remain alert to dangerous fire weather conditions.
People in affected areas should follow the latest forecasts and take precautions to prevent fires from starting.
