Cape Town - Two of the three fires threatening historic wine estates in Somerset West are still raging, City of Cape Town Fire Management said on Wednesday.
"The fire which was burning on the farm threatening the Lourensford wine estate has died down, what was left to burn on the farm has been burnt," Senior Communications Officer Winston Davids said.
Firefighters were still battling fires on two other farms which were threatening the Vergelegen and Knorhoek wine estates.
Davids said over 70 firefighters and emergency personnel were on the scene.
"They are working in shifts, each shift ends at 09:00 every morning... that's when we send in fresh legs," he said.
Davids said that two helicopters, one from the SA National Defence Force and the other from Working on Fire, were on hand to drop water bombs.
On Tuesday, the helicopters could not take flight because of the dense smoke which hindered the visibility of the pilots.
"There is very dense fog in the area at the moment, the smoke density is not as bad as yesterday, so helicopters may take off a bit later."
Hot weather, heavy winds
Davids said the fires started about a month ago in the Grabouw area. Hot weather and heavy winds resulted in the fires flaring up, and spreading to Somerset West.
"They start off small, and are fuelled by hot and windy weather conditions. As we extinguish the fires, hot spots remain high up on the mountains, and then flare up once again by the wind... sometimes it is very windy, causing the fires to spread very fast."
The cause of the fires remained undetermined.
Animals were evacuated off the farms, and no one was injured in the blaze.
He was not sure how much longer the fires would burn.
"If we do not put it out, then there would be nothing left to burn soon," Davids said.
