The Nairobi Expressway has temporarily waived toll fees for motorists exiting via the Southern Bypass and Eastern Bypass (Exit A) due to severe flooding on Mombasa Road.

• The toll waiver is a measure by Moja Expressway Company to mitigate traffic congestion caused by heavy rains and waterlogging on the A8 section.
• Moja Expressway Company, the private operator of the expressway, announced the waiver on Friday, May 1.
• Motorists can still access the expressway from Mlolongo towards the city centre but must exit via the specified bypasses to benefit from the fee suspension.

Heavy overnight rains have caused widespread flooding across Nairobi, rendering key transport routes impassable and disrupting daily life, particularly on Saturday, May 1.

• Mombasa Road is impassable between Mlolongo and Cabanas, with traffic backed up for nearly 3km.
• The National Police Service had previously warned residents to stay alert, citing rapidly rising water levels in major rivers throughout Nairobi.
• Flooding has also affected other major roads including Jogoo Road, Landhies Road, and the Nairobi Expressway, with the Nairobi Commuter train service from Syokimau to Nairobi disrupted.

A tragic head-on collision occurred this morning along the Narok-Bomet highway, resulting in multiple fatalities and injuries.

• Four people were confirmed dead at the scene.
• The accident involved a lorry and a saloon car, with preliminary reports indicating the lorry veered off its lane.
• Narok Police Commander Patrick Lobolia confirmed the incident as investigations are underway.

Heavy rains across Kenya are expected to significantly reduce by mid-May 2026, according to the Kenya Meteorological Service Authority (KEMSA). However, the agency warns of ongoing risks and potential damage before the cessation of the rainy season.

• The March-April-May 2026 rainfall season is predicted to end in the latter half of May, with generally drier conditions expected, although some regions like Central Kenya and the Coast may see rain into June.
• KEMSA advises continued caution due to the risk of flooding, damage to infrastructure and agriculture, and health risks like waterborne diseases and malaria.
• The authority also warned of potential river overflows and flash floods in low-lying areas due to excess inflows into rivers, dams, and drainage systems.

Kenyans can anticipate a reduction in heavy rainfall by mid-May, according to the Kenya Meteorological Department. The long rains season is expected to significantly ease in the latter half of the month, providing much-needed respite after weeks of downpours.

• The Kenya Meteorological Department forecasts drier-than-average conditions from the second half of May.
• Despite the easing, the first week of May still poses risks of flooding and disruptions.
• The end of the long rains will usher in a cool and dry season, with potential temperature drops in the Highlands.
