Ekurhuleni's Disaster and Emergency Management Services department (DEMS) has alerted residents to be on the lookout for possible floods this week.
The warning comes in awake of weather forecasts showing a 80-100 percent chance of showers and thundershowers in the municipality and the entire Gauteng province from Tuesday through to the weekend.
DEMS said heavy rains may also result in rivers, low lying bridges, open trenches, furrows, culverts and even canals to flood causing damage to adjacent and down streams areas that may not receive any rainfall.
"Parents with children walking to school are also urged to be cautious in contemplating their safety when crossing flooded water streams," said DEMS
The emergency department also warned pedestrians and drivers to avoid crossing under subway bridges, low lying bridges as well as swollen streams with water above the ankle level.
"If you can`t see the road surface because of the flood water, turn around and use alternative roads," said the department.
