The South African Weather Service (SAWS) has issued a Yellow Level 2 Weather Warning for Gauteng, alerting residents to the possibility of disruptive thunderstorms. Heavy downpours, damaging winds, hail, and localised flooding are expected, particularly in the southern and central parts of the province.
Emergency services across Gauteng are on high alert, and residents are urged to take precautions to protect lives and property as storms develop through the afternoon and evening.
What the Yellow Level 2 Weather Warning Means
SAWS uses a colour-coded system to help South Africans understand the seriousness of weather events. A Yellow Weather Warning signals potentially dangerous conditions, while the Level 2 rating indicates a moderate chance of the event occurring.
This type of warning does not mean the entire province will be severely affected. Instead, it highlights the likelihood of localised disruptions, which may include flooded roads, damage to infrastructure, and dangerous travel conditions.
What Forecasters Are Saying
SAWS forecaster Lehlohonolo Thobela said thunderstorms would stretch across Gauteng and into neighbouring provinces.
“You can expect isolated to scattered showers and thundershowers into the afternoon, covering the Northwestall the way to parts of KwaZulu-Natal and the southern parts of Limpopo. For tomorrow, just isolated showers and thundershowers are expected over Gauteng and the North West, as well as into the Free State province,” Thobela explained.
This outlook shows that while Gauteng may face widespread storms today, conditions should ease slightly tomorrow.
Hazards to Expect Under the Yellow Level 2 Warning
Heavy Rainfall and Flooding
Rainfall of 15–25 mm is forecast, with some downpours reaching 30–40 mm in parts of Gauteng. This level of rain increases the risk of flooding in low-lying areas, informal settlements, and roads with poor drainage.
Strong and Damaging Winds
Gusty winds could uproot trees, damage structures, and create hazardous driving conditions. Loose items around homes should be secured to prevent injury or damage.
Hail and Lightning
Hailstorms may damage vehicles, crops, and rooftops, while frequent lightning strikes pose fire hazards and risks to personal safety.
Emergency Services on High Alert
The Johannesburg Emergency Management Services (EMS) has confirmed that teams are prepared to respond to weather-related incidents.
EMS spokesperson Robert Mulaudzi urged residents to avoid flooded roads and stay indoors during thunderstorms. “Our teams are monitoring the situation closely and are on standby to assist communities. We urge the public to remain cautious and prioritise safety,” he said.
Impact on Gauteng Communities
The weather system will not impact all of Gauteng equally, but southern and central regions face the highest risk.
- Transport Disruption: Submerged bridges and flooded roads are already affecting traffic in some areas.
- Power Interruptions: Strong winds and lightning may cause outages in certain suburbs.
- Vulnerable Housing: Informal settlements are especially at risk of flooding and wind damage.
eNCA has reported that several roads remain closed due to storm-related flooding.
Safety Advice for Residents
Residents are encouraged to take simple but important steps during the Yellow Level 2 Weather Warning:
- Avoid floodwaters: Do not attempt to cross flooded bridges or roads.
- Secure outdoor items: Strong winds can turn loose objects into dangerous projectiles.
- Stay indoors during storms: Limit movement until conditions improve.
- Prepare for outages: Keep torches, charged phones, and basic supplies on hand.
- Follow official updates:Check SAWS announcements and trusted news outlets for real-time information.
Why Staying Informed Matters
Weather conditions in Gauteng can change quickly, and what begins as isolated showers can escalate into intense thunderstorms. Even a Yellow Level 2 Weather Warning can cause serious local damage if ignored.
Gauteng Weather Outlook
The Yellow Level 2 Weather Warning underlines how vulnerable the province is to sudden storms. While not catastrophic, these conditions still pose risks of flooding, hail, and travel disruption.
Authorities urge residents to remain vigilant, take precautions, and avoid unnecessary travel. By preparing in advance and following official advice, communities can limit the impact of severe thunderstorms.
