Kenya Met Warns Of Five-Day Heavy Rainfall In Several Counties

The Kenya Meteorological Service Authority (KMSA) has released an updated weather advisory cautioning the public about a significant increase in rainfall expected across various parts of the country between April 22 and April 27, 2026.

The warning, issued on April 21, highlights the likelihood of intensified downpours, particularly in the coastal, northeastern, and southeastern lowland regions.

According to the advisory, rainfall activity is set to become more widespread and heavier over the forecast period, with some areas projected to record substantial accumulations.

In particular, the Coast and adjacent regions could experience rainfall amounts exceeding 20 millimetres within a 24-hour period. This level of precipitation raises concerns about potential flooding and related hazards, especially in vulnerable and low-lying areas.

The authority specifically identified several counties that are likely to be most affected by the heavy rains. These include Kwale, Mombasa, Kilifi, Tana River, and Lamu along the Coast.

In the northeastern region, Garissa County, as well as parts of Wajir and Mandera, are also expected to experience intensified rainfall. Additionally, counties in the southeastern lowlands, namely Taita-Taveta, Kitui, and Makueni, have been listed among the areas at risk.

Beyond the rainfall itself, the advisory also warns of accompanying weather conditions that could pose further risks. Gusty winds exceeding 25 knots, equivalent to approximately 12.5 metres per second, are expected in some locations.

Such winds may lead to reduced visibility, minor structural damage, and hazardous conditions for both road users and those in open areas.

Along the coastal strip, marine conditions are forecast to deteriorate significantly during the advisory period. Wave heights are expected to rise above two metres, creating rough sea conditions that could endanger small vessels and disrupt maritime activities. As a result, operators in the maritime sector have been urged to exercise caution and take necessary safety measures to minimize risks.

KMSA has also cautioned residents about the possibility of floods and flash floods, particularly in regions prone to poor drainage or located near rivers and water channels.

Notably, the authority emphasized that flooding may also occur in areas that do not directly receive heavy rainfall, especially those situated downstream, where rising river levels can lead to unexpected inundation.

Members of the public have been strongly advised to remain vigilant throughout the period and to take precautionary steps to ensure their safety. This includes avoiding walking or driving through flooded roads or fast-moving water, as such conditions can be extremely dangerous and unpredictable.

People are also encouraged to steer clear of open fields during thunderstorms and to avoid taking shelter under trees or near structures like grilled windows, which may increase the risk of lightning strikes.

The authority reiterated its commitment to closely monitoring the evolving weather situation and assured the public that timely updates will be provided should conditions change.

Residents are encouraged to stay informed through official communication channels and to adhere to all safety advisories issued during this period of heightened weather activity.
