Forecasts said Tropical Cyclone Batsirai is increasing in intensity and is expected to pass north of the Indian Ocean island nation of Mauritius on Wednesday evening and make landfall in central Madagascar on Saturday afternoon.
The Global Disaster Alert and Co-ordination System said Batsirai has been upgraded and classified as Category 4.
Madagascar’s meteorology directorate has alerted seafarers and issued cyclone alerts in 16 districts projected to be in the storm’s path.
The GDACS forecasts that the cyclone has the potential to intensify in the next 48 hours, posing serious threats to Mauritius, Madagascar and the French overseas department of Reunion.

The WMO said the 2022 cyclone season in the Indian Ocean is expected to end in April with the exception of the Seychelles and Mauritius, where it is expected to end in May.
