Find out what the latest weather forecast from the SA Weather Service means for your region.

The moderate tropical storm Filipo, which is nearing the coast of southern Mozambique, is expected to also affect the extreme north-east parts of South Africa.

The South African Weather Service (Saws) said the weak, embryonic tropical low-pressure system experienced significant intensification overnight on Sunday.

According to the weather service, the storm is expected to affect mostly the southern parts of Mozambique, but some of its effects will also be felt over the extreme north-eastern parts of South Africa.

“It is estimated that Filipo will make landfall this evening on the Mozambican coast at or near Inhassoro, north of Vilankulos, having further intensified to a ‘Severe Tropical Storm’, associated with average winds between 89 and 118 km/h.”

“Therefore, for much of the southern Mozambican coastline, a high risk exists for weather-related damage from a combination of torrential rain, strong, damaging winds (with wind gusts well more than 100 km/h), as well as storm surges near the coastline.”

Tropical Storm Filipo impact on SA

For South Africa, Saws said deterministic NWP modelling from a number of sources has produced high-confidence guidance indicating that most of the heavy rain, at least for Monday and Tuesday, will stay confined to southern Mozambique.

Despite this, there is a moderate to high chance that Tuesday and Wednesday will see extremely heavy rainfall across the lowveld regions of Mpumalanga and Limpopo, respectively.

For Mpumalanga, there is a chance of orographically enhanced rainfall along the eastern Escarpment region on Wednesday. Localised flooding and heavy rain are possible over the neighbouring Kingdom of Eswatini, the southern Lowveld (which includes the Kruger National Park), and the extreme northeastern KwaZulu-Natal (KZN).

The Olifants, Letaba, Sabie, and Sand rivers, as well as the Crocodile River in the far south of Kruger National Park (KNP), are among the major rivers that are projected to flow quite forcefully, probably in flood, starting midweek.

Similarly, a stretch of prolonged, exceptionally heavy rainfall is predicted on Wednesday in the northeastern region of KwaZulu-Natal, particularly along the coast and in the nearby hinterland north of Richards Bay.

By Thursday, the intense rain will stop completely as the system passes east of South Africa, out of southern Africa, and into the southern Indian Ocean.

“The Saws will continue to monitor any further developments relating to this weather system and will issue subsequent updates as required.”

A yellow level 4 warning for disruptive rainfall leading to flooding roads and settlements, difficult driving on dirt roads, damage to infrastructure, and mud-based houses is expected over the north-eastern parts of KwaZulu-Natal and the lowveld regions of Limpopo and Mpumalanga from Wednesday morning.

Saws also issued an orange level 6 warning for disruptive rainfall leading to flooding roads and settlements, difficult driving on dirt roads, damage to infrastructure, and mud-based houses over Umkhanyakhude District Municipality, uPhongolo, Nongoma, and uMfolozi local municipalities in KwaZulu-Natal, as well as the Nkomazi Local Municipality (southern lowveld) in Mpumalanga from Wednesday morning.
