MIDDELBURG – Two short-lived tornadoes struck the eastern highveld of Mpumalanga on Thursday, 1 January, causing property damage but no loss of life, according to the South African Weather Service (SAWS).
The tornadoes occurred near Middelburg and Carolina during widespread severe thunderstorm activity that affected the province on New Year’s Day, SAWS confirmed in a media statement on Monday afternoon.
Assessment reveals property damage
SAWS conducted a damage assessment in the Middelburg area on Friday, 2 January, despite communication challenges caused by the severe weather. Internet connectivity was unavailable, with locals attributing the outages to the previous day’s thunderstorm.
Access restrictions to private farms prevented a comprehensive survey, but damaged communication lines along Stoffberg Road and uprooted tree branches indicated the tornado’s path. The damage patterns suggested that tornadoes in the area might be underreported due to limited access for assessments, according to SAWS.
Eyewitnesses reported strong winds and large hail around 18:00 on New Year’s Day. One witness observed a funnel-like feature beneath clouds near Stoffberg Road. Farm workers returning home encountered severe weather conditions, including frequent lightning, and were forced to seek shelter in nearby settlements.
According to SAWS, satellite analysis revealed signs of a rotating thunderstorm between 17:40 and 17:50, with the system organising into two cells. Weather analysts noted that when thunderstorms rapidly approach each other, they tend to produce tornadoes – phenomena that are particularly difficult to predict and warn against due to their rapid development.
No surface damage assessment was conducted for the Carolina tornado due to access restrictions and time constraints.
Weather warnings issued in advance
SAWS had issued Level 2 and Level 4 warnings for severe thunderstorms affecting Mpumalanga and KwaZulu-Natal on 1 January. The Level 4 warning indicated low likelihood but potentially significant impacts, highlighting risks of damaging winds, large hail, and heavy rainfall.
Researchers from the Vaal University of Technology have been conducting focused studies on tornadoes in Mpumalanga. SAWS continues to enhance post-event verification processes, particularly in regions where numerical data collection is limited, working with academic institutions to improve categorisation and forecasting techniques.
Weather warnings are updated daily and available through the SAWS website (www.weathersa.co.za), radio and television broadcasts, social media platforms, and the WeatherSMART mobile application.
