1999–2000 South-West Indian Ocean cyclone season
The storm turned toward the east on April11 away from land. Convection organized thereafter into an eye feature, but was weaker than thunderstorms in typical tropical cyclones, resulting in its subtropical classification.[3] The MFR estimated peak 10‑minute winds of 95km/h (60mph) on April12,[50] noting that the system should have been named, but also that its "structure has had no recent analogue in [the basin]."[3] Meanwhile, the JTWC issued three tropical cyclone formation alerts, but never issued advisories.[43] An increase in wind shear deteriorated the eye feature and the convection, promptly causing weakening. On April15, the circulation dissipated off the southwest coast of Madagascar.[3]
