WINDHOEK, 27 DEC (NAMPA) Several regions have received good rains on Wednesday, with the heaviest thunder showers falling in the north-central and Kavango regions.
According to a report released by the Namibia Meteorological Services (NMS) on Thursday, Grootfontein (Otjozondjupa Region) and Tsumeb (Oshikoto Region) received the highest amount of rainfall of 57 millimeters (mm) and 36mm, respectively.
Oshikango (Ohangwena Region) and the Ondangwa Airport (Oshana Region) received over 20mm of rainfall, while Rundu (Kavango East Region) received over 17mm.
Pauline Mufeti, an NMS chief hydrologist, reported that the water levels of some perennial rivers have risen tremendously due to the heavy rains that were received during the last couple of weeks.
Mufeti said the Zambezi catchment has caused an increase in the Zambezi River as recorded at Katima Mulilo (Zambezi Region).
Perennial rivers such as the Kavango and Kongola have also recorded above-normal water levels when compared to recordings taken the same time in past years.
The Zambezi River recorded a water level of 1.04 metres, compared to 0.79m which is the normal water level for this time of the year.
The Kwando River in the Kongola area recorded a water level of 2.92m, compared to the normal level of 2.27m, while the Kavango River in the Rundu area recorded a water level of 4.90m, compared to a normal level of 4.42m.
Mufeti indicated that when river levels are above normal, it does not necessarily mean the situation is critical.
Sudden fluctuations must be read with care, as they may have been caused by power plants that often release water into the river system, she explained.
Places which recorded less than 10mm of rain on Wednesday were the Rundu Airport with 9.8mm, Okongo (Ohangwena Region) with 1.1mm and Bagani (Kavango East Region) with 0.4mm.
