The first half of the week was characterized by the collapse of the cores of both the South Atlantic and the southern Indian high pressure cells. At around Wednesday, both cores only measured 1018 mB, and were located relatively far offshore.

When the South Atlantic high is weak and its core displaced to the south, its immediate effect on the south-west coast of Africa is much reduced. During summer, this core typically stays offshore, slipping around Cape Agulhas on its regular passage from west to east. But its outer rim at 1016 mB has a dirct impact on the western half of South Africa, Botswana, Namibia and the south-western quarter of Angola. The effects are most visible in the atmosphere’s lower strata from ground level to about 18,000 feet, i.e. the so-called 500 mB surface.

This week’s progressive synopsis showed just how important the South Atlantic high is for local weather.

The transport of moisture from the Indian Ocean continued every day, following more or less the southern limit of the Inter-Tropical Convergence Zone. This means substantial moisture penetrates the Namibian atmosphere from Zambia and Botswana. The origin is the Indian Ocean and the path runs across Mozambique, Zambia, Zimbabwe and Botswana until it eventually reaches central and southern Angola, as well as Namibia.

This intrusion carries a high vapour load, it is light and buoyant. It brings in lots of clouds, which, like everyday this week, penetrates deep into Namibia up to the edge of the escarpment. Depending on local conditions, in may even descend down the western face of the escarpment onto the coastal plain. In essence, the north-eastern airflow creates conditions that are conducive to rain.

Enters the South Atlantic high from the south-west. It is cold, dry and dense. It creeps up the Namibian coastline from south to north, pushing across the coastal plain until it encounters the escarpment where the air starts to ascend, depending on the strength of the low pressure system over the Namibian interior. The impact from the South Atlantic high creates numerous local events which are unpredictable, at least on a localised scale.

At the beginning of this week, a strong cyclonic circulation was present on the surface over the Namibia Angola border. This circulation was driven by the northern extension of the South Atlantic high. But instead of obliterating the intrusion of moisture, it energized the low pressure circulation, drawing in moisture from Zambia, enhancing convection and producing spectacular rainfall over Kavango West, Owamboland and the Kunene Region.

This system migrated south with the bias to the west. In its wake it rained over Kunene, Erongo (up to the coast), Otjozondjupa, Khomas, Hardap and even Karas. On weathermaps, the progression could be seen clearly as the system developed from a low pressure intrusion into a full-blown trough that ran from the Kunene Region through Namibia and through South Africa up to its southern coast at Port Elizabeth.

What’s Coming

The intrusion of moisture from Zambia and Angola continues throughout the weekend but it is opposed on the surface by the South Atlantic high. A very prominent convergence zone stretches from the Erongo Region to the Kalahari, through Botswana and into South Africa.

Local rainfall conditions remain positive during the weekend but only for the northern half of Namibia. This continues into Monday.

Meanwhile, a tropical depression just north of Madagascar is expected to develop into a proper Tropical Storm, moving closer to the island’s east coast and migrating southwards, becoming stronger as it does. By Friday afternoon, this depression has already evolved into a moderate tropical storm labelled Enawo with winds around 35 knots.

The development of Enawo will replicate conditions of three weeks ago when “Carlos” developed in about the same spot, also following a trajectory close to the Malagasy coastline, moving from north to south.

The combination of low pressure over northern and western Namibia, amplified by the zonal airflow from Madagascar to Zambia, portend well for local rainfall.

From Tuesday onward, rainfall expectations are very positive for the whole country but the bias remains in the north, the north-west, and the western escarpment down to the Orange River.

Following reverse listing, public can now acquire shareholding in Paratus Namibia


20 February 2020, Windhoek, Namibia: Paratus Namibia Holdings (PNH) was founded as Nimbus Infrastructure Limited (“Nimbus”), Namibia’s first Capital Pool Company listed on the Namibian Stock Exchange (“NSX”).

Although targeting an initial capital raising of N$300 million, Nimbus nonetheless managed to secure funding to the value of N$98 million through its CPC listing. With a mandate to invest in ICT infrastructure in sub-Sahara Africa, it concluded management agreements with financial partner Cirrus and technology partner, Paratus Telecommunications (Pty) Ltd (“Paratus Namibia”).

Paratus Namibia Managing Director, Andrew Hall

Its first investment was placed in Paratus Namibia, a fully licensed communications operator in Namibia under regulation of the Communications Regulatory Authority of Namibia (CRAN). Nimbus has since been able to increase its capital asset base to close to N$500 million over the past two years.

In order to streamline further investment and to avoid duplicating potential ICT projects in the market between Nimbus and Paratus Namibia, it was decided to consolidate the operations.

Publishing various circulars to shareholders, Nimbus took up a 100% shareholding stake in Paratus Namibia in 2019 and proceeded to apply to have its name changed to Paratus Namibia Holdings with a consolidated board structure to ensure streamlined operations between the capital holdings and the operational arm of the business.

This transaction was approved by the Competitions Commission as well as CRAN, following all the relevant regulatory approvals as well as the necessary requirements in terms of corporate governance structures.

Paratus Namibia has evolved as a fully comprehensive communications operator in Namibia and operates as the head office of the Paratus Group in Africa. Paratus has established a pan-African footprint with operations in six African countries, being: Angola, Botswana, Mozambique, Namibia, South Africa and Zambia.

The group has achieved many successes over the years of which more recently includes the building of the Trans-Kalahari Fibre (TKF) project, which connects from the West Africa Cable System (WACS) eastward through Namibia to Botswana and onward to Johannesburg. The TKF also extends northward through Zambia to connect to Dar es Salaam in Tanzania, which made Paratus the first operator to connect the west and east coast of Africa under one Autonomous System Number (ASN).

This means that Paratus is now “exporting” internet capacity to landlocked countries such as Zambia, Botswana, the DRC with more countries to be targeted, and through its extensive African network, Paratus is well-positioned to expand the network even further into emerging ICT territories.

PNH as a fully-listed entity on the NSX, is therefore now the 100% shareholder of Paratus Namibia thereby becoming a public company. PNH is ready to invest in the future of the ICT environment in Namibia. The public is therefore invited and welcome to acquire shares in Paratus Namibia Holdings by speaking to a local stockbroker registered with the NSX. The future is bright, and the opportunities are endless.
