Meteorological technician at the Namibia Meteorological Service (NMS) Olga Tjiueza told Nampa on Friday that the heat-wave experienced here over the past few weeks is a result of high-pressure systems in the atmosphere which are causing air to sink, with no air escaping, while temperatures keep rising.
Tjiueza stated that extreme hot conditions will prevail until Saturday, while heat conditions will ease as from Sunday.
“Tropical moisture is expected over the eastern half of Namibia and a few thunder showers are expected as from Monday,” she noted.
Meteorologists have previously indicated that local weather patterns differed last year as most of the country had already experienced rain during January. This year temperatures have been way above normal, with a maximum average of 35.8 degrees Celsius this year compared to an average of 31.2 degrees Celsius during the same period last year.
South Africa also experienced an intense heat-wave over the past week with sunny and mild conditions up to 28 degrees Celsius expected over the next seven days, according to the South African Weather Service.
Meanwhile, the United Nations Office for the Co-ordination of Humanitarian Affairs (UNOCHA) in its latest situation report (No 2) issued on Thursday for the Southern African Development Community (SADC) Region warned that while the flood response in southern Mozambique is continuing, new cases of flooding are being reported in northern Mozambique.
“Tropical Cyclone Felleng is moving parallel to the eastern coast of Madagascar, and while not projected to make landfall, flooding is still expected. River levels are also high across the region,” it stressed.
At least 48 people have died in severe floods that have devastated southern Mozambique over the past few weeks. Some 250 000 people have been affected, of which 146 000 people are still being housed in temporary shelters. Access to some areas continues to be an issue, with many roads and bridges washed away, according to the report.
Seychelles, hit by a series of rare floods and landslides, declared a state of emergency on 28 January this year, while in Botswana, flooding due to extremely heavy rains has been reported in the north-east and central districts of that country.
