Intense Tropical Cyclone Haruna (16S)  struck Madagascar at about 18:00 GMT on 21 February. Data supplied by the US Navy and Air Force Joint Typhoon Warning Center suggest that the point of landfall was near 22.2 S, 42.4 E. Haruna brought 1-minute maximum sustained winds to the region of around 185 km/h (114 mph). Wind gusts in the area may have been considerably higher.

According to the Saffir-Simpson damage scale the potential property damage and flooding from a storm of Haruna’s strength (category 3) at landfall includes: storm surge generally 2.7-3.7 metres (9-12 feet) above normal, some structural damage to small residences and utility buildings with a minor amount of curtainwall failures, damage to shrubbery and trees with foliage blown off trees and large trees blown down, mobile homes and poorly constructed signs are destroyed, low-lying escape routes are cut by rising water 3-5 hours before arrival of the centre of the storm, flooding near the coast destroys smaller structures with larger structures damaged by battering from floating debris, terrain continuously lower than 1.5 metres (5 feet) above mean sea level may be flooded inland 13 km (8 miles) or more, and evacuation of low-lying residences within several blocks of the shoreline may be required. There is also the potential for flooding further inland due to heavy rain.
