The Sierra Leone Meteorological Agency (SLMet) has issued its first-ever weather warning using the Common Alerting Protocol (CAP), marking a significant step in strengthening the country’s early warning systems and advancing the digital transformation of meteorological services. The alert, issued over the capital, warned of light dust conditions across Freetown, which could reduce visibility and pose health risks, particularly for individuals with respiratory conditions. Residents were advised to limit outdoor exposure, while drivers and marine transport operators were urged to exercise caution.
According to SLMet, the warning was generated using the CAP Composer, an open-source alerting tool integrated into the agency’s newly developed national meteorological website. The system enables forecasters to produce standardized warnings in line with international best practices and disseminate them in real time. Officials say the adoption of CAP will significantly improve the speed, consistency, and reach of public alerts. By facilitating seamless sharing across multiple communication platforms and institutions, the protocol ensures that critical weather information reaches communities, emergency responders, and policymakers promptly.
The development marks a key milestone in Sierra Leone’s broader efforts to modernize climate services through digital innovation. By leveraging open-source technologies and strengthening digital infrastructure, SLMet is enhancing its capacity to deliver timely, reliable, and accessible weather information. The initiative also aligns with the global “Early Warnings for All” campaign, launched by United Nations Secretary-General António Guterres, which seeks to ensure universal access to life-saving early warning systems by 2027.
Experts note that standardized protocols such as CAP are essential to achieving this goal, as they enable rapid and consistent dissemination of alerts across systems and borders. With this first CAP-enabled alert, Sierra Leone joins a growing number of countries adopting modern, interoperable technologies for hazard communication, an important step toward enhancing national resilience and safeguarding lives and livelihoods against weather-related risks.
