MODERATE TROPICAL STORM ANA DOES NOT POST ANY DIRECT THREAT TO SOUTH AFRICAÂ
This weekend saw the first tropical system of the 2021/22 tropical cyclone season for the Southwest Indian Ocean Basin. Towards the end of last week, a tropical low began rapidly intensifying over the open ocean to the northeast of Madagascar, northwards of Mauritius and Reunion islands. ‘Over the weekend, the system turned gradually from east to west over central and northern Madagascar, temporarily losing intensity due to surface friction with the landmass, as well as the absence of the release of latent heat energy from the ocean surface (the main energy driver for tropical cyclones). ‘Overnight, the system continued to intensify, reaching Moderate Tropical Storm intensity in the early hours of Monday morning, leading to its official naming of ‘Ana’. ‘The system tracked westwards and by local sunrise on Monday morning, was lying just off the northern Mozambican coastline between Angoche and Mogincual. The system then tracked in an easterly direction.
