South Africa Under Dual Weather Threat: Severe Thunderstorms in Northeast, Heatwave in Cape Provinces

Severe Weather Warnings Issued by SAWS

The South African Weather Service (SAWS) has alerted the public to significant weather events unfolding across the country. A Yellow Level 2 warning for severe thunderstorms has been issued for parts of Limpopo and Mpumalanga, while a persistent heatwave continues to affect the Cape Provinces. These warnings highlight a dual weather challenge for South Africa, urging residents to remain vigilant and take necessary precautions.

Thunderstorm Threat in Limpopo and Mpumalanga

For Friday, October 10, 2025, SAWS has forecast severe thunderstorms over the central and western parts of Limpopo and Mpumalanga. This Yellow Level 2 warning indicates a medium likelihood of significant impacts. Expected conditions include heavy downpours that could lead to localized flooding, the presence of large amounts of small hail, and potentially damaging winds. Further impacts may involve localized damages to informal and formal structures, roofs, and carports. The risk of service disruptions, such as power surges, and bodily injuries caused by lightning is also present. Specific areas in Limpopo under alert include Mogalakwena, Lepele-Nkumpi, Molemole, Greater Tzaneen, Maruleng, Makhado, Polokwane, Blouberg, Modimolle/Mookgopong, Lephalale, Greater Letaba, Fetakgomo/Greater Tubatse, Makhuduthamaga, Elias Motsoaledi, and Ephraim Mogale. In Mpumalanga, Thaba Chweu is among the municipalities identified.

Heatwave Grips Cape Provinces

Simultaneously, a brutal heatwave is baking parts of the Western Cape and Northern Cape. Temperatures are expected to soar into the high 30s and low 40s Celsius, with places like Upington potentially reaching 35°C and Vredendal pushing 40°C. This extreme heat poses several risks, including:

• Veld fire dangers: Extremely high fire danger conditions are anticipated, particularly in areas such as Kamiesberg, Matzikama, Hantam, and Khâi-Ma, where fire danger indices could exceed 75.
• Health concerns: The heat can lead to conditions like hyperthermia and heatstroke, especially affecting vulnerable groups such as the elderly, children, and outdoor workers.

Residents in affected areas are advised to stay hydrated, wear light clothing, and avoid direct sun exposure between 10:00 and 16:00.

Understanding SAWS Warnings and Safety Advice

The SAWS employs an impact-based warning system, using a color-coded scale (Yellow, Orange, Red) and levels from 1 to 10 to communicate the likelihood and severity of weather events. A Yellow Level 2 warning signifies a medium likelihood of minor to moderate impacts. For those in thunderstorm-affected areas, SAWS recommends avoiding crossing swollen rivers, securing loose outdoor items, and unplugging appliances during storms. In heatwave regions, it is crucial to stay indoors during peak heat, use fans or air conditioning, and refrain from making open fires.
