Nairobi residents are waking up to a stark warning today, Friday, March 20, 2026. The Kenya Meteorological Department (KMD) has issued a fresh heavy rainfall advisory, warning that the current downpour is set to intensify significantly over the next 72 hours.
According to the weatherman, the intensity is expected to peak between Friday (today) and Sunday (March 22), with rainfall amounts likely to exceed 20mm within a 24-hour period. This comes at a time when the city is already reeling from a devastating start to the March-May “long rains” season, which has already claimed lives and displaced thousands across the country.
The “Saturation” Risk: Why This Weekend is Different
Unlike the rains seen earlier this month, this weekend’s downpour falls on already saturated soils. Since late February, Nairobi has experienced prolonged wet spells, meaning the ground has lost its ability to absorb more water.
The Result: Even moderate rainfall can now trigger immediate flash floods. The water has nowhere to go but into our streets, our drainage systems, and unfortunately, our homes.

While the entire metropolitan area will be affected, the KMD and local authorities have flagged specific neighborhoods for “extreme vigilance”:
The “Triple Threat”: Floods, Lightning, and Power
The advisory isn’t just about water; it’s about the secondary hazards that often prove more lethal.
Flash Floods: These can appear in minutes, even in areas where it hasn’t rained heavily, as water moves downstream from the Aberdare ranges.
Lightning Strikes: Residents are strictly advised not to shelter under trees or stand near grilled windows during thunderstorms.
Electrocution: With over 30 fatalities in Nairobi already linked to drowning and electrocution this month, stay away from fallen power lines and submerged electrical boxes.
Survival Guide: How to Stay Safe This Weekend
If You Are Driving:
The 6-Inch Rule: Just six inches of fast-moving water can knock you off your feet, and a foot of water can sweep away most cars. If you see water crossing the road, Turn Around, Don’t Drown.
Visibility: Heavy rain reduces visibility to near zero. If you must drive, keep your headlights on and maintain a significant following distance.
Avoid “River Roads”: Stay away from low-lying bridges and roads that run parallel to the Nairobi and Ngong rivers.
If You Are at Home:
Clear the Drains: If it is safe to do so, ensure the small drainage channels around your compound are clear of plastic waste and debris.
Elevate Valuables: If you live in a flood-prone area (like South C or Mukuru), move electronics and important documents to higher shelves today.
Power Down: During heavy lightning, unplug sensitive electronic devices to prevent damage from power surges.
The Public Health Warning
The Ministry of Health has also issued a parallel alert. Saturated soils and flooded latrines are a recipe for water-borne diseases like cholera.
Boil All Water: Even if it looks clean, assume tap water is contaminated during a flood.
Avoid Wading: Do not walk through floodwaters barefoot; the risk of leptospirosis and other infections is high.
Conclusion: Community Vigilance
This weekend will be a test of Nairobi’s infrastructure and our community spirit. As we navigate these heavy rains, check on your neighbors—especially the elderly and those in informal settlements who may be most vulnerable to rising water levels.
Keep your phone charged, stay tuned to local radio for emergency broadcasts, and remember: no journey is worth your life. Stay indoors unless it is absolutely necessary to travel.
