Photos and videos shared by residents and motorists showed cars sitting helplessly in murky brown water that had risen to nearly half their height.
In some cases, the floodwater covered the wheels and lower doors of the vehicles, raising fears that the engines and electrical systems could have been severely damaged.
Motorists who had left their cars in the parking area rushed back after learning about the flooding, only to find the situation already out of control.
Some stood nearby watching as the water continued to rise, unsure of how they would retrieve their vehicles safely.
Others attempted to assess the damage while hoping the water would drain once the rain stopped.
Business owners operating near Aga Khan Walk said the flooding happened very quickly.
According to some traders, the drainage systems in the area appeared overwhelmed by the sudden heavy rainfall, causing water to accumulate faster than it could flow away.
Within a short time, the sunken parking lot turned into what many described as a “temporary pool.”
Several people gathered around the scene as emergency teams and security officers tried to assess the situation.
Some efforts were made to direct water away from the area, but the amount of rainfall made it difficult to control the flooding immediately.
Urban planners and residents have long raised concerns about flooding in parts of Nairobi’s central business district, especially in areas where drainage systems are blocked or unable to handle large volumes of rainwater.
Low-lying spaces such as underground parking lots are particularly vulnerable when storms strike.
The incident at Aga Khan Walk has renewed discussions about the need for better stormwater management in the city.
Experts say improvements in drainage infrastructure, regular clearing of blocked channels, and better urban planning could help reduce such incidents in the future.
For many car owners affected by the flooding, the immediate concern remains the cost of repairing potential water damage.
Vehicles exposed to floodwater often face problems with engines, electronics, and interior components.
