Warning for heavy rain

The Namibia Meteorological Service has warned that heavy rainfall is expected over the south-eastern parts of Namibia tonight.
This, as a surface low over south-western Namibia deepens and will cause strong winds over the interior to persist.
The weather office said that cool afternoon temperatures are also expected due to the advection of cold air from the west tomorrow.
Rain in the form of isolated thundershowers were already expected in the Kavango regions, Zambezi, east of Otjozondjupa and Omaheke from yesterday.
However, today, a few isolated thundershowers over the eastern half on the interior are expected with scattered thundershowers most likely over Otjozondjupa and Khomas in places.
Weather experts have warned that an upper cyclone system has developed across the Atlantic Ocean which will swing over the western side of southern Africa during its waning phase.
An upper cyclone is a cold-core low pressure system with closed circulation in the upper air.
It will apparently cause a seasonal transition that aims to deliver high volume rain over southern Africa.
Strong winds
Meanwhile, LandWater warned that the upper cyclone system could mean strong gusts of wind from the west for Namibia, while it could bring more rain to South Africa.
“Extensive higher-volume rain and very strong gusts - Namibia should take special note of the wind - will swing in towards the middle of the week from the west, but with scattered and lower-volume coverage over the wider western coastal belts, with rain more towards South Africa than Namibia,” it said.
Although it is still uncertain how much rain Namibia will receive from this system, it is expected that a second and third upper trough system will follow.
“However, this is an evolving picture and things can quickly get bad in Namibia,” LandWater warned.
It explained that the current system is developing in three phases, which means it can build up to "trigger extensive, high-volume rains over large parts of southern Africa".
This can be followed in the week of 25 October and again from 1 November with a second and third system.
