Cheneso still active in Mozambique
According to the weather service, for much of this week, severe tropical storm Cheneso has aimlessly swirled around in the eastern part of the Mozambique Channel, just off the western coast of Madagascar, without much overall movement of the system.
Given that Cheneso is currently classified as a ‘Severe Tropical Storm’, sustained winds around the core, or vortex, of the system can be expected to be fairly damaging, of the order of 89 to 118 km/h.
This video is no longer available.
Very rough seas, in the region of 4 to 6 metres, can also be expected in the vicinity of the system.
By Saturday, 28 January, ‘Cheneso’ is expected to adopt a more southerly track, passing close to Europa Island.
“Given current guidance from numeric weather prediction models (NWP), the South African Weather Service (SAWS) can confidently state that this system is not expected to directly affect South Africa.”
