Weather update: Expect on/off rain for rest of week

JULY 22, 2015

According to the Port Elizabeth office of the SA Weather Services, expect intermittent rain for Wednesday and the rest of the week.

"In a nutshell rain is expected on and off over most of the Eastern Cape for the rest of the week, with clearance from the west only expected around Sunday evening," Garth Sampson, SA Weather Services spokesperson for the Eastern Cape, said in a statement.

In detail the general outlook for the week is as follows: 

Wednesday 22 July - An upper trough, located west of the country will draw in moisture over the region producing showers and thundershowers across the province.

Thursday 23 July - Another upper trough and surface cold front approaches causing showers and thundershowers across most of the Eastern Cape.

Friday 24 July – The cold front moves through the Eastern Cape with a temporary break in rainfall in the morning. The rainfall returns in the afternoon/evening for the province as a high pressure system ridges in along the coast. Light snowfalls are possible overnight on the Sneeuberg and southern Drakensberg.

Saturday 25 July - A cut-off low will be situated over the western Free State with the ridging high south of the country. This will cause freezing levels to drop significantly resulting in cold conditions with heavy showers of rain. Snow can be expected over the high lying areas with disruptive snow over the Sneeuberg and southern Drakensberg mountains. Heavy rain with flooding is expected in the former Transkei area.

Sunday 26 July - The cut-off low will move out along the KwaZulu-Natal coastline with onshore flow still producing showers. Heavy rain is expected in the extreme east of the province. Snowfalls are expected to continue on the northern mountains.

Monday 27 July – A high pressure system moves over the province causing clear conditions.

Considering that some significant falls were recorded towards the end of last week and further persistent rain is expected this week, the ground will become supersaturated in places. This can lead to localized flooding even with less significant falls. It is advised to listen to the radio or visit for the latest forecasts and warnings.
