Africa: Weekly Weather Forecast for 23 – 29 Jan 2023

Africa: Africa Weather Forecast launched their weekly summary (23 – 29 Jan 2023). As per African weather reports, scattered storms will be over the central interior most of the week, followed by hurricanes in the east much later in the week after the Tropical Storm has exited Madagascar and moved towards the southern Mozambique Channel before turning east.

There’s an upper trough peaking on Tuesday while passing through the Western Cape and fizzles out towards the Eastern Cape on Wednesday morning. While at the same time, the rest of the country will be affected by a high-pressure cell so gigantic it extends to Namibia and Botswana. 

However, a different picture plays at the surface, one of widespread surface convergence east of a surface trough lingering in the west, connected to the tropics and keeps redeveloping in the afternoons, initiating scattered storms over the central interior most days of the week.

It is partly cloudy in the northeast and parts of the central and south-eastern interior, with a high chance of light rainfall from scattered storms over the central and south-eastern interior. 

Otherwise, fine and warm to hot elsewhere. Temperatures in Gauteng (the lower 30s) and western KwaZulu-Natal (mid to upper 30s) are expected to surpass #heatwave thresholds until Tuesday afternoon in KwaZulu-Natal. In contrast, Gauteng and neighbouring provinces will most likely remain hot throughout the week.

High chance of light showers and thunderstorms in the west and central interior but moderate in places along the southern Drakensberg.

High chance of showers and thundershowers over the central and eastern provinces on Wednesday but low in Gauteng. Fine and hot in western Limpopo and west of Prieska in the Cape. Medium chance of moderate to slightly intense rainfall along the east coast between Durban, Nkandla and Richard’s Bay.

On Thursday and Friday, isolated storms are expected over the central interior, particularly in provinces surrounding Lesotho on Thursday but more along the southern escarpment on Friday. 

Both days will experience light rainfall amounts as a high-pressure cell settles in the northeast, supported by #Tropical Storm Cheneso in southern parts of the Mozambique Channel.

A widespread, persistent southerly flow along the south and southeast coasts supply a significant amount of moisture into Western Cape, Eastern Cape and KwaZulu-Natal with a high chance of light-to-moderate rainfall over the three provinces on Saturday, partly cloudy elsewhere in the east but fine and hot in the far west. 

Very low chance of afternoon or evening showers over the central parts but medium to high in places as far east as Gauteng and western Mpumalanga on Sunday.
