Storm Overview
Classification and Season
Severe Tropical Storm Ana was a significant meteorological event, designated as the fourth-deadliest tropical cyclone globally in 2022. It was the first named storm of the 2021โ22 South-West Indian Ocean cyclone season, originating from an area of convection designated as Invest 93S northeast of Madagascar.[2]
Intensity Metrics
According to Mรฉtรฉo-France La Rรฉunion (MFR), Ana reached its peak intensity as a Severe Tropical Storm with 10-minute sustained winds of 95 km/h (60 mph) and a minimum pressure of 987 hPa. The Joint Typhoon Warning Center (JTWC) also reported peak 1-minute sustained winds of 95 km/h (60 mph) with a lowest pressure of 993 hPa.[1]
Temporal Extent
The storm's lifecycle spanned from its formation on 20 January 2022 to its dissipation on 26 January 2022. Its trajectory significantly impacted multiple nations in Southern Africa.
Meteorological History
Genesis and Development
Initial ensemble forecasts indicated potential development northeast of the Mascarene Islands. By 20 January 2022, the JTWC identified Invest 93S. Mรฉtรฉo-France noted a developing circulation, influenced by monsoonal flow. The system gradually consolidated, leading to its classification as a tropical depression by MFR on 22 January.[4][9]
Track and Landfall
Ana made landfall in Madagascar as a tropical depression, crossing the island and entering the Mozambique Channel. Conditions in the channel facilitated re-intensification into a tropical depression. On 24 January, MFR upgraded it to Moderate Tropical Storm Ana. It subsequently made landfall near Angoche, Mozambique, before weakening into an overland depression and moving across Malawi and Zimbabwe, eventually becoming a remnant low over Zambia.[10][16]
Devastating Impact
Overall Consequences
Tropical Storm Ana resulted in significant loss of life and widespread destruction across Madagascar, Malawi, and Mozambique. The storm's aftermath was compounded by the need for relief efforts amidst the threat of subsequent cyclones, such as Cyclone Batsirai.[20]
Infrastructure Damage
In Malawi, the storm's heavy rainfall caused extensive flooding and damage. Notably, the Kapichira Hydroelectric Power Station, responsible for approximately 30% of the nation's electricity supply, sustained damage, leading to intermittent power outages across the country.[25][27]
Madagascar Impact
Human Toll and Displacement
Prior to its intensification into a moderate tropical storm, Ana made landfall in Madagascar as a tropical depression. The associated heavy rainfall triggered deadly landslides and floods, causing 58 fatalities within the country.[21] An estimated 55,000 individuals were displaced, with an additional 130,000 seeking refuge in temporary shelters.[22][23]
Malawi Impact
Fatalities and Displacement
The southern regions of Malawi, particularly around Mulanje, experienced severe impacts. As of 31 January, 37 fatalities were reported, with 22 individuals missing and 158 injured.[25] Approximately 200,000 people were displaced from their homes, with over 109,000 residing in emergency camps.[25]
Widespread Power Outages
The storm led to nationwide electricity disruptions in Malawi. The aforementioned damage to the Kapichira Hydroelectric Power Station significantly impacted the country's energy infrastructure, resulting in prolonged power outages.[25]
