Heavy rain, storms, and destructive winds expected in South Africa on Monday

Residents of several provinces in South Africa have been warned about the start of the week, which is expected to be rainy and potentially disruptive, as heavy rain, severe thunderstorms, and destructive winds are forecast for Monday.

The South African Weather Service (SAWS) has issued a series of warnings based on potential impacts for Monday, September 14th. The most serious is a Level 4 Yellow Warning for disruptive rain over parts of the Western and Northern Cape.

This warning is due to extensive rain and thunderstorms expected in many areas of the western and central parts of the country.

Flood threat due to heavy rainfall

According to SAWS data, there is an 80% probability of rain and thunderstorms over a vast area stretching from parts of the Western Cape to the Northern Cape. In other parts of the Northern Cape and the central inland region, there is a 60% chance of downpours and thunderstorms, while in some areas of the Eastern Cape and KwaZulu-Natal, the probability of rain is 30%.

Isolated showers are also expected in parts of Limpopo and Mpumalanga with a probability of around 30%. The Level 4 Yellow Warning for disruptive rain covers the territories of the Western Cape and parts of the Northern Cape. SAWS warns that the precipitation may lead to flooding of roads and settlements, as well as cause serious disruptions to transport.

Severe thunderstorms threaten the Northern and Western Cape

Additionally, a Level 2 Yellow Warning for severe thunderstorms has been issued for parts of the Northern and Western Cape. These storms could trigger localized flooding on vulnerable roads, low-lying areas, and bridges, and cause local damage to settlements in open areas.

A Level 1 Yellow Warning for severe thunderstorms is in effect in parts of the Eastern Cape, where storms are capable of damaging settlements and temporary structures, as well as causing local power and communication outages.

Destructive winds will blow across inland areas and the coast

Strong winds will exacerbate the complex weather conditions on Monday. A Level 2 Yellow Warning for destructive winds applies to a large inland area, including parts of the Northern Cape, North West province, Free State, and Limpopo. The weather service warns of possible localized damage to settlements.

Along the coastlines of KwaZulu-Natal and the Eastern Cape, Level 1 and Level 2 warnings for destructive winds are in effect. The Level 2 warning for the coast includes a risk to the navigation of small boats and vessels, as well as possible disruptions to small harbors, ports, and beach activities. In other areas along the affected coast, destructive winds may cause localized damage to settlements, power and communication outages, and hinder navigation.

Прогноз погоды по регионам

In Gauteng, the day is predicted to be fine and cool, though it will warm up significantly in the far north of the province. Due to the high UVB sunburn index, individuals spending long periods outdoors must take necessary sun protection measures.

Mpumalanga will begin the day with localized morning fog in the east, after which conditions are set to clear, leading to fine weather that ranges from cool to warm for the remainder of the day. Similarly, south-eastern Limpopo is forecast to have morning fog patches before transitioning into fine and cool to warm weather.

The North West region is expected to remain fine, with temperatures fluctuating between cool and warm. In the Northern Cape, much of the province will be fine and warm to hot, despite partly cloudy skies predicted in the southeast. Isolated afternoon showers and thundershowers have a 30% chance of occurring in the southeastern sections of this province.

Along the Northern Cape coastline, moderate to fresh winds blowing from the south to the southeast are anticipated. The Free State will start with morning fog patches in its eastern areas; otherwise, conditions will be fine and cool to warm, though the south may become partially cloudy.

The Western Cape is set to encounter morning fog along its southern coast, with other areas being partly cloudy and warm. Light rain is forecast along the south coast, where the chance of rain is noted at 30%. Coastal winds there are generally expected to be moderate south-easterly, potentially increasing to fresh or strong in the afternoon, while winds along the south coast itself will be moderate south-westerly. The province's UVB sunburn index is projected to be very high.

The western portion of the Eastern Cape will feature cool weather with light rain and morning fog near the coast. Inland areas will be partly cloudy and warm to hot before cloud cover intensifies later in the day, with a 30% likelihood of isolated showers and thundershowers. Moderate to fresh south-westerly winds are expected along the coast, sometimes strengthening to strong gusts. In contrast, the eastern half of the province will initially be fine before becoming partly cloudy and warm, while areas situated north of the escarpment will stay cool.

KwaZulu-Natal is expected to see morning fog patches over its northern interior before conditions settle into fine and cool to warm weather. Moderate to fresh northerly to north-easterly winds are forecast along the coast, and the UVB sunburn index is expected to be very high.

In summary, Thursday promises predominantly dry and stable weather for the northern and central parts of South Africa, whereas the southern regions will contend with intermittent rain and thunderstorms.
