This is due to persistent heavy rain, with "more heavy rain expected tonight into tomorrow".
"This will cause serious strain on emergency services. Take extreme caution in these areas," SAWS said.
Tropical storm Eloise is currently over the north of the country.
Roads are flooding, as is the Kruger National Park where rivers are overflowing and all gravel roads closed.

On Saturday snow fell in Malibu, an unusual occurrence that prompted drivers to get out their cars to play by the side of the road, pictured on social media
The surprise arrival of snow and hail in the LA County caused both delight to locals who pulled out sleds, and increased road traffic accidents.
Drivers along the Malibu Canyon Road posted photos and videos on social media of them getting out their cars in wonder and playing in the light powder in an area where temperatures in January don't usually drop lower than 20F.
The photos were a sharp contrast to just days earlier when beach-goers enjoyed unexpected temperatures in the 80s.
Deaths were reported in 10 prefectures — Hokkaido, Aomori, Iwate, Miyagi, Akita, Yamagata, Niigata, Toyama, Ishikawa and Fukui.
People aged 70 or over accounted for 48 of the deaths. In many cases, older people died after falling from a roof while removing snow.
Local officials say that people should avoid clearing snow from the roof by themselves.
"There were arms everywhere," ecologist Drew Harvell told The Atlantic's Ed Yong last year. "It looked like a blast zone."
The dismal remains of these animals, who are usually capable of regenerating their own limbs, were strewn along the entire West Coast of North America, in one of the largest mass wildlife mortality events ever recorded. Over 20 species of sea stars were perishing.
In some areas, sunflower star (Pycnopodia helianthoides) populations dropped by an average of around 90 percent in weeks, a loss that saw this once common and abundant species vanish from most of its range in just a few years.
The victims died in the worst-hit port city of Beira, most of them killed by falling trees, authorities said.
Cars were submerged in water, walls of some low lying buildings collapsed and swathes of land were flooded in the city, posts on social media showed.
The districts of Buzi and Nhamatanda were affected by severe flooding.
Mozambique President Filipe Nyusi is set to travel to the area.

The International Space Station spotted an exotic type of upside-down lightning called a blue jet (illustrated) zipping up from a thundercloud into the stratosphere in 2019.
A blue jet - a bolt of lightning that shoots upwards from thunderstorm clouds - has been spotted from the International Space Station.
The phenomenon was spotted by the European Atmosphere-Space Interactions Monitor (ASIM) near the island of Naru in the Pacific Ocean.
In an article published in the science journal Nature, astronomers describe seeing five intense blue flashes, each lasting about 10 milliseconds.
Four of the flashes were accompanied by a small pulse of ultraviolet light, which appear as rapidly expanding ring. They are formed by the interaction of electrons, radio waves and the atmosphere and are known as elves (Emissions of Light and Very Low Frequency Perturbations due to Electromagnetic Pulse Sources).













Comment: Mass mortality events caused by algae blooms are in the news more often recently, and the correlation of ocean anoxia with previous extinction level events is likely to be warning sign of what's to come:
- "A new phenomenon": Mass marine life die off in ANOTHER location in Russia's Kamchatka region
- Earth's expanding ocean anoxic zones and the correlation with periods of geologic upheaval
- Mysterious new invasive algae smothering Hawaii's coral reefs
- Neurotoxic algae that is poisonous to marine life and humans advancing along the Pacific coast
- Worldwide ocean anoxia driven by global cooling was possible factor in previous mass extinctions
