Indian Ocean coral bleaching


16 February 2019 – moderate to high bleaching is still expected in Mauritius, Reunion, the Seychelles, and across N. Madagascar into the N. Mozambique Channel

Overall, moderate to high bleaching is still expected in the central and northern parts of the WIO. Tropical storms continue both east and west of Madagascar, dissipating some of the heat in these areas. However as the WIO warm pool expands towards the equator and mainland, the risk of bleaching in Mauritius, Reunion, the Seychelles, and across N. Madagascar into the N. Mozambique Channel continues.      Download the full alert at right ->
