As a consequence of Cyclone Idai, which occurred during March 2019, depths, coastline and sea levels may have changed throughout this area. Wrecks and obstructions may have been displaced. Tidal predictions may be unreliable and aids to navigation may have been damaged, destroyed or be out of position. Mariners should expect considerable change and seek local knowledge when making for ports or seeking refuge.
Mariners are advised to navigate with extreme caution in the area.
