The Ghana Meteorological Agency (GMet) has issued an impact-based weather alert warning of moderate to heavy rainfall, thunderstorms, strong winds and possible localised flooding in several parts of the country on Saturday, June 13, 2026.
According to the agency, a previously forecast band of rain-bearing clouds has developed over sections of the coastal and inland areas and is expected to produce moderate to heavy rainfall, with or without thunderstorms, across affected regions.
In its latest weather update issued at 0745 UTC, GMet indicated that parts of the Western, Central, Greater Accra and Volta regions are likely to experience rainstorms between 0745 UTC and 1000 UTC. The agency classified the threat level in these areas under the “Be Prepared” and “Be Aware” categories, signalling the potential for weather-related disruptions.
The northern sector is also expected to experience significant adverse weather conditions. Regions including the Upper East, North East, Northern, Upper West and Savannah are forecast to receive heavy rainfall accompanied by thunderstorms between 0745 UTC and 1400 UTC.
GMet further warned that portions of the Upper West and Savannah regions could face heightened weather risks between 0945 UTC and 1500 UTC. These areas have been assigned a higher alert category, requiring residents and local authorities to take precautionary measures to minimise potential impacts.
The agency cautioned that the expected storms may be accompanied by moderate to strong winds capable of damaging weak structures, uprooting trees and disrupting transportation and other outdoor activities.
In addition, GMet warned of the likelihood of localised flooding in low-lying and flood-prone communities, particularly in locations that experience intense rainfall within a short period.
Residents in affected regions have been advised to remain vigilant, avoid unnecessary travel during periods of heavy rainfall, secure loose objects around homes and workplaces, and stay away from floodwaters, open drains and other hazardous areas during the storms.
The agency continues to monitor the evolving weather system and has urged the public to follow official forecasts and advisories for further updates throughout the day.
