South Indian Ocean Marine Weather Outlook

A ridge of high pressure prevails across the South Indian Ocean, mostly between 32S and 42S latitudes.  Far to the south, an intense 948mb low near 57S/19E is moving eastward and weakening. Post-Tropical Cyclone Batsirai is now well south of Madagascar (near 36S/43E) and is accelerating southeastward.
