Meteorological Agency Warns:
Strong and Dusty Winds; Risk of Floods

In a press conference held at the Sierra Leone Meteorological Agency’s (SLMet) headquarters on Friday, May 5, 2023, the agency revealed its highly anticipated 2023 Seasonal Forecast, highlighting the agro-climatic characteristics expected during the upcoming rainy season.
The forecast, developed using advanced meteorological tools, historical data spanning from 1992 to 2022, and expert knowledge, paints a worrisome picture of what lies ahead for the country. Gabriel Kpaka, the Deputy Director General and Head of Operations at SLMet, expressed concerns about various climate-related risks, including strong and dusty winds, thunderstorms, lightning, the risk of floods (including urban-induced flooding in July, August, and September), outbreaks of pests and insects, and the development of germs.
Analyzing the current configuration and future projection of ocean surface temperatures, Kpaka warned of an impending deficit in rainfall. He explained, “We have observed that the sea surface temperature remains warm up to March, indicating a potential shortage of rainfall. From now until July, the Southern part of Sierra Leone will experience higher temperatures compared to the Northern part, although both regions will be warmer than usual.”
The Deputy Director General continued, “During the rainy season, we anticipate an increase in temperature, particularly during dry spells. Disturbingly, from June to August, Sierra Leone is projected to face a rainfall deficit, which is a cause for concern. It’s important to note that a rainfall deficit doesn’t mean we won’t have rainy days, but rather a decrease in the overall amount of rainfall.”
Kpaka emphasized the potential risks associated with the expected torrential rains in July, August, and September. Without adequate precautions, these heavy rains could lead to disastrous consequences. He urged farmers to take precautions and adjust their traditional farming methods to the changing climate patterns. Late planting seasons are expected, with a significant delay in rainfall, indicating that farmers should wait before sowing their seeds.
The SLMet official stressed the importance of relying on meteorological information to make informed decisions. He highlighted the likelihood of a long dry spell toward the end of the season, prompting farmers to be prepared. Additionally, Kpaka noted an increased frequency of thunderstorms in October, raising concerns for sectors such as aviation.
To mitigate the identified risks, Kpaka suggested strengthening communication channels for seasonal forecasts, enhancing the monitoring and response capacities of agencies responsible for flood management, disaster risk reduction, and humanitarian aid. He also stressed the importance of avoiding uncontrolled occupation of flood-prone areas and the need to clean sewer channels to facilitate rainwater evacuation. Furthermore, Kpaka called for improved access to high-quality seeds and agricultural inputs tailored to farmers’ needs and encouraged the adoption of climate-smart techniques to enhance crop and fodder production.
With the alarming forecast in hand, Sierra Leone must heed the warnings and take proactive measures to safeguard lives, livelihoods, and the nation’s future against the potential impacts of the upcoming rainy season.
