A south-easterly swell is expected to affect the coastal regions from Atsimo-Andrefana to Anosy and from Anosy to Diana. Significant wave heights are forecast to range from 3.0 to 3.5 metres, with waves reaching up to 4.0 metres along the north-eastern coastline. These conditions may pose a threat to maritime activities and coastal communities.
