“The heavy rainfall is likely to intensify to more than 30mm in 24hrs on 22nd, 23rd and 24th February 2026 and spread to the Southeastern lowlands and the Coastal region especially south Coast,” the statement added.

The intensity is, however, projected to reduce on February 25.

The advisory, classified under moderate to heavy severity with a “moderate probability of occurrence (33% to 66% chance),” is expected to guide preparedness efforts among national and county disaster response agencies.
