Cape Town – The South African Weather Service has alerted the Western Cape to a strong cold front, expected to hit on 14 June and into 15 June.
“Significant rainfall amounts can be expected from Thursday morning, where spells of heavy downpours are likely from late morning into the afternoon. Accumulated rainfall amounts of 10- 25 mm can be expected, but 30-50 mm over the mountains,” a media statement from the SA Weather Service said.
“Further intermittent rain and showers are expected to continue over the western half of the Western and Northern Cape Provinces on Friday, with a further 10-20 mm likely over the western mountains.”
The province was also warned of gale force north-westerly winds (65-70 km/h), which were expected between Cape Columbine and Cape Agulhas on Thursday.
“Strong to Gale force and gusty crosswinds along the N1 highway may result in this major route, as well as corresponding rail transport, being adversely affected,” the Weather Service said.
“Hazardous driving conditions may result in road accidents along this route. Moreover, high-sided vehicles are at risk of being toppled by intense wind gusts along the route.”
It added that gale force, gusty winds may result in localised damage to informal as well as formal structures and infrastructure.
“Travel routes may also be affected due to fallen trees and wind-blown debris.”
According to the Weather Service, heavy rain leading to flooding is expected over the City of Cape Town, Cape Winelands, western parts of the Overberg and West Coast District on Thursday and extending into Friday.
“As the cold front makes its way to the south-eastern parts of the country on Friday 16 June 2018, strong to near-gale force westerly to south-westerly winds (50-6 km/h) can be expected along the Eastern Cape coast with wave heights between 5 to 7 m,” the Weather Service said.
Temperatures over the high lying areas of the Western and Eastern Cape as well as the southern parts of the Northern Cape are expected to drop significantly, with certain areas reaching very cold conditions.
By Saturday, the cold front would have exited the country and the cold, dry air will spread to the interior of the country, resulting in cold daytime conditions over the Free State, North West Province, Gauteng as well as Mpumalanga.
