Senegal is highly exposed to heatwaves and sustained high temperatures, with impacts ranging from heatstroke to worsening cardiovascular illnesses. Despite having robust meteorological data, a lack of integration between the Senegalese meteorological service (ANACIM) and the Ministry of Health (MoH) hampered effective early warning systems for heatwaves, leading to a critical information gap that failed to mitigate adverse health impacts during extreme weather events.
