The Kenya Meteorological Department (Kenya Met) has reported improved accuracy and reliability in its weather forecasting systems, citing strengthened communication channels and enhanced early warning dissemination to institutions.

The updates come as the country continues to experience ongoing rainfall across multiple regions.

David Koros, Assistant Director of Forecasting Services, while speaking during an interview on Monday night, May 4, 2026, said the department’s forecasts have improved due to more structured communication and timely updates to relevant agencies.

Kenya Met says continued improvements in forecasting and early warning systems are supporting disaster preparedness efforts across the country. With ongoing rains contributing to flooding and landslides in several regions.

“So far, we have issued a prediction concerning the weather over this week, which includes, among other counties, Nairobi. We expect continuation of the rainfall around Lake Victoria Basin, Central, Coast for the entire part of this week. However, we expect to have some reduction in terms of intensities. For the month, we expect to have reduced intensities towards the end of the month,” Koros said.

He added that coordination with institutions such as county governments has improved the speed and use of weather alerts.

“We have strengthened our communication and dissemination structure to the level that we are now updating early warning, and we are disseminating to the right institution, one of which is Nairobi County. They get it on time, so it is upon them to act on it. We get feedback through the media, and up to now, we can see that our feedback is fairly good in terms of accuracy and reliability. We do updating at a regular basis,” he said.

Rainfall and weather alerts across regions

Kenya Met has maintained weather advisories in recent days as rainfall continues across several parts of the country. On May 1, 2026, the department issued an alert warning of heavy rainfall and strong winds between May 1 and May 3, 2026, affecting the Rift Valley, Lake Victoria Basin, Coast, and parts of northeastern Kenya.

The advisory noted the likelihood of thunderstorms in the afternoon and evening, with wind speeds exceeding 25 knots in low-lying and coastal areas. Residents in flood-prone regions were urged to avoid crossing moving water and to take precautions during storms.

A subsequent update shared on May 4, 2026, indicated continued rainfall across the Highlands East and West of the Rift Valley, Lake Victoria Basin, Coast, Southeastern Lowlands, and parts of Northwestern and Northeastern Kenya.

Health risk alerts linked to weather patterns

Kenya Met has also expanded its forecasting scope to include health-related risk assessments based on weather conditions. In a bulletin released on May 2, 2026, the department flagged increased malaria risk in Nandi County following a temperature rise of 1.7°C above long-term averages.

The bulletin indicated an epidemic risk level of 30 per cent, above the 20 per cent threshold, attributing the increase to warmer conditions that support mosquito breeding in highland areas. Kisii County recorded no risk, while Kakamega stood at 22.7 per cent.

The assessment was developed in collaboration with the Kenya Medical Research Institute (KEMRI) and the Ministry of Health, highlighting the role of temperature in disease transmission patterns.

The department continues to issue regular updates, urging the public and institutions to rely on official forecasts for planning and safety measures.
