1.2 March 2025 Test Refer to the infographic below based on Tropical Cyclone Bheki. The Mauritius Meteorological Service has issued a class one (out of four) cyclone warning for Rodrigues Island. Winds are expected to gradually increase and seas will become increasingly rough as the storm system approaches the island. Sustained heavy rainfall could trigger flooding in low-lying areas and those with easily overwhelmed drainage systems. Localized evacuations, flash flooding, and landslides are possible. The inclement weather could trigger localized business, transport, and utility disruptions, rendering some bridges or roadways impassable. Flight disruptions at regional airports and temporary closures of ports are also possible. Stagnant pools of water during and after flooding increase insect- and waterborne diseases, such as dengue fever, cholera, and malaria. Raw sewage and other hazardous materials mixed with floodwaters pose a serious health threat.
