peak intensity of 120 kt the next day. Maximum sustained winds just prior to
landfall in Madagascar were estimated at 110 kt. Nadia turned west-southwest on
23 March while moving off the west coast of Madagascar. It turned west on 24
March and moved into Mozambique on 25 March. The storm maintained hurricane
intensity during this period, with maximum sustained winds estimated at 85 kt
just prior to landfall. Nadia quickly dissipated as a tropical cyclone over
land, although a residual low pressure area persisted over Mozambique at the
end of the summary period. While Nadia affected Madagascar and Mozambique,
there are no reports of significant winds. The minimum reported pressure was
996 mb at Nosy Be, Madagascar at 2100 UTC 23 March. Nampula, Mozambique re-
