october alex dissipated storm developed east west time warning responsibility expanded area responsibility severe tropical november area convection formed southwest sumatra south equator moved southwestward slowly developed distinct low pressure area november system strengthened storm west began tracking storm november reached estimating winds mph days later nearby ship reported winds mph time storm moved generally west southwestward crossing november time renamed storm continued westward gradually weakened november deteriorated tropical depression status dissipating days later tropical cyclone middle december active southern indian_ocean northeast madagascar circulation developed december preceded development tropical disturbance december moving west northwest system slowly developed shifting southwest december system intensified moderate tropical storm passing north madagascar briefly developing eye feature satellite presentation degraded land interaction convection

basin reached minimum pressure mbar inhg moderate tropical storm active end january coast spawning distinct circulation january southeast tropical disturbance trough system moved west southwestward madagascar february system named gradually intensified days later storm moved ashore eastern madagascar peak winds mph weakened crossed country emerged february south storm intensified peak intensity turned west northwest february final landfall central dissipating soon striking country days affected region brought additional rainfall peak hour total storm produced peak winds mph caused flooding landslides particularly area lake storm damaged roads eastern madagascar capital city rail connecting city deaths country moderate tropical storm tropical storm developed january east central madagascar moved offshore turned south february storm intensified peak winds mph turning westward moving ashore steered ridge dissipated later day producing wind gusts mph storm moved dropped rainfall flooded isolated towns floods washed away bridges knocked power lines moderate tropical storm february tropical disturbance formed north quickly intensified tropical storm day moving southwest storm attained peak winds mph february passed northwest mauritius island mountainous peak recorded gusts mph storm continued southwest change intensity weakening slightly february day turned west northwest executed tight loop progressing southward turning southeast storm dissipated february tropical cyclone active middle march northeast madagascar spawned low pressure areas march westernmost tropical

coastal towns northeast southwest damaged houses crops roads destroying storage shed storm changing trajectory offshore ship attempted avoid storm sail mph gusts waves flooded deck damaged later passed near island producing waves intense tropical cyclone low pressure persisted end april equator developed spiral area convection april preceded development tropical disturbance day time system tropical storm status given moving southwest storm strengthened organized ridge south steered east april approaching trough turned southeast following day enhanced atmospheric instability helped storm strengthen tropical cyclone status april day attained peak winds mph developing defined eye increased wind shear progressively cooler waters weakened cyclone turned south storm weakened tropical depression status dissipated day storms tropical depression formed south february given moved southward initially reaching winds mph ridge south turned system north dissipated february near formed short lived tropical depressions end february formed february northeast moved southward mauritius bringing days heavy rainfall depression turned west northwest dissipated february day depressions formed including madagascar given moved westward dissipated february reaching winds mph depression originated southwest coast madagascar february system passed south island moving southeastward
