Flood Warnings Issued for KwaZulu-Natal
The South African Weather Service has issued a Yellow Level 2 warning for disruptive rainfall along the KZN south coast. Localised flooding is expected, particularly in low-lying areas, informal settlements, and regions near rivers and bridges. Motorists should anticipate difficult driving conditions and possible road closures.
Rainfall Totals Expected in KZN
Forecast models predict 30 to 50mm of rain for parts of southern KZN on 19 July. Heavy rainfall increases the risk of flash flooding, especially where the ground is already saturated or drainage is poor.
Impact on Informal Settlements and Infrastructure
Many vulnerable communities in KZN remain at greater risk during such storms. Floodwaters could damage homes, roads, and essential infrastructure, leading to displacement, disrupted transport, and health hazards. Authorities are urging families in at-risk areas to prepare for possible evacuations and remain alert for official advisories.
