For more details, you can find additional information on the Zambezi Flood Plain and the flood emergency declared in response to the heavy rains.
8. Hennops River Flood
The Hennops River is one of the most polluted rivers in Gauteng.
Poorly maintained sanitation facilities in areas like Tembisa, Ivory Park, and Olifantsfontein have contributed to its condition.
During heavy rains, the river often floods, leading to significant damage to nearby communities. The river’s high level of Escherichia coli makes the water dangerous for residents during these floods.
The floods also impact the environment, harming local wildlife and vegetation. The constant pollution and flooding are serious issues that need addressing to improve the river’s health.
9. Lelewela Cyclone
The Lelewela Cyclone struck Namibia with unexpected force.
This storm, which formed in the Indian Ocean, traveled westward before hitting the Namibian coast.
Lelewela caused significant damage to coastal towns. Winds reached speeds that disrupted daily life and infrastructure. Many homes and buildings were destroyed.
Heavy rains from the cyclone led to severe flooding. Rivers overflowed, impacting both urban and rural areas. The agriculture sector suffered as crops were washed away.

Meteorological Conditions Leading to Massive Storms
The formation of massive storms in Namibia is influenced by a mix of geographic and climate factors. These conditions shape how and when storms develop, impacting both intensity and frequency.
Geographic Factors Influencing Storm Formation
Namibia’s location on the southwestern coast of Africa and its proximity to both the Atlantic Ocean and the Namib Desert play key roles in storm formation.
The cold Benguela Current, running along the coast, influences weather patterns significantly. This current brings cold, nutrient-rich waters up from the depths, affecting temperature and humidity levels in the region.
Mountains and highlands in the interior also contribute. The elevation changes create varying air pressures that can lead to turbulent weather.
Additionally, Namibia’s coastal plains and deserts experience extreme temperature fluctuations between day and night. These shifts can cause low-pressure systems that may develop into storms.
Climate Patterns Impacting Namibia
Climate patterns like El Niño and La Niña have a major impact on Namibia’s weather.
El Niño often leads to drier conditions, while La Niña can bring increased rainfall and storm activity. Both patterns cause shifts in sea surface temperatures in the Pacific Ocean, which then influence weather far beyond that region.
Another important factor is the Intertropical Convergence Zone (ITCZ), a belt of low pressure near the equator where trade winds from the Northern and Southern Hemispheres meet.
When the ITCZ moves northward, it can bring moist and unstable air to Namibia, contributing to storm development.
Seasonal variations also play a role.
From November to April, the rainy season, storms are more frequent. During this time, tropical cyclones from the Indian Ocean may also affect Namibia, particularly in the northeastern regions. These combined factors create a complex environment for storm formation in the country.
Historical Context of Major Storms in Namibia
Namibia, situated between the Kalahari and Namib deserts, has experienced significant storms throughout its history. These storms have had far-reaching effects on the country’s landscape and people.
Recent Notable Storms
In recent years, Namibia has seen a rise in storm activity, leading to severe weather events.
For example, the 2011 flood affected nearly 500,000 people, displacing over 60,000.
This flood highlighted the vulnerability of communities and the need for improved disaster preparedness. Increased flooding and drought have become more frequent, affecting around 70,000 people annually.
Another major event was a massive dust storm captured by satellites.
The storm originated from Namibia’s Central Plateau, spreading dust over the Atlantic Ocean. Such events demonstrate the severe weather patterns that impact not only Namibia but also neighboring regions.
Long-term Impact of Historical Storms
Historical storms have had enduring effects on Namibia’s environment and society. The country’s high central plateau spawns berg winds, which contribute to dust transportation.
Such winds have been observed for many years, affecting local agriculture and air quality.
