Cape Town - Very hot and hazardous conditions are expected over the Northern and Western Cape, but there is some light rain relief.
The South African Weather Service warns fire hazardous conditions will be in place over the entire Western Cape, except the Cape Metropole, as well as the western parts of the Northern Cape - as temperatures will hover around the late 30s and Vredendal will once again tip the mercury at 40°C on Human Rights Day Tuesday, 21 March.
While the extreme heat is expected to continue later into the week, a cold front is approaching from the west and is expected to pass the southern parts of the Western Cape by Thursday.
A 30% chance of rain can be expected across most of the Western Cape, the southern parts of the Northern Cape near Prieska and Vanwyksvlei. A slight chance of rain could also be expected over much of the Eastern Cape, the south-easterly parts of the Free State as well as across Lesotho.
Thunder and lighting already hit parts of Cape Town on Monday night, providing a drop of relief for the province in the grips of a drought.
Very little rain has been forecast elsewhere in the country for Tuesday, however a 30% chance of isolated showers has been forecast over northern regions of Limpopo, along the borders with Zimbabwe and Mozambique, across the areas of Thohoyandou and Giyani.
A 30% chance of rain has also been forecast across Botswana, with heavy rains across these regions seeing higher than normal incidents of Malaria being reported. Travellers heading to Botswana or those who find themselves in Limpopo need to ensure they take the correct preventative measures as a warning has been issued for high levels of malaria in both of these regions.
The Ministry of Health and Wellness for Botswana has issued a warning that the country is experiencing a high level of malaria, following the recent heavy rains. "There have been increases in the number of cases in Okavango, Ngami, Chobe, Boteti, Tutume and Bobirwa. Travel agents are advised to warn their clients to seek medical advice two weeks before travelling to malarial areas."
The Limpopo Health Department has also announced an increase in the number or reported malaria cases in the province, particularly around Lephalale and Thabazimbi.
Conditions will be cool to start off with across most of SA, with areas in Northern Cape around Sutherland and the Free State's Bethlehem and the south-eastern parts of Gauteng near Ermelo can expect a chilly start to the day. For the rest a fine and mild day can be expected as the extremely hot conditions in the west will persist.
Johannesburg in Gauteng will reach 27°C, while Pretoria will reach 29°C. Bloemfontein in the Free State will peak at 30°C.
