Kenya Met Warns More Flooding After Recording 160 mm Rainfall at Wilson Airport

The Kenya Meteorological Department (KMD) has warned that moderate to heavy rainfall will continue across several parts of Kenya until March 9, 2026, maintaining the risk of flooding, landslides, and water contamination.

In a press release dated March 7, Kenya Met stated that the heavy rainfall advisory issued on March 3, 2026, remains in force, as weather conditions continue to produce isolated storms expected to bring between 40mm and 100mm of rain in some areas.

“The advisory warns that moderate to heavy rainfall is expected to continue through the weekend (7th to 8th March 2026), with isolated heavy storms of 40mm to 100mm in some locations. Rainfall may persist into early next week, maintaining elevated risks of flooding, landslides, and water contamination,” read part of the press release.

KMD said the current weather conditions are part of a prolonged wet spell that began in mid-February 2026, following the March–April–May (MAM) seasonal rainfall onset forecast issued on February 18.

Authorities added that they will continue monitoring the situation and issue updates to help communities prepare and respond to potential hazards.

Some weather stations recorded heavy rainfall in the past 24 hours, including:

  • Moi Airbase – 145.4 mm
  • Kabete – 117.4 mm
  • Dagoretti – 112.2 mm
  • Thika – 59.6 mm

Kenya Met explained that 20mm of rainfall equals about 20 litres of water per square meter, enough to quickly overwhelm drainage systems and increase flood risks.

The meteorological department expressed regret over the damage to infrastructure and disruption to livelihoods caused by the ongoing rains and assured the public that it will continue to closely monitor the evolving weather situation.
