The SA Weather Service was not sure on Tuesday whether tropical storm Irina would return to South African this weekend.
"There is a difference of opinion on whether the tropical storm will come back close to the coast again, or if it will stay far away from the coast," weather spokesman Mnikeli Ndaba said.
Ndaba said the tropical storm was located 748km east of Durban and would not have an impact on land. There would, however, be rough seas along the KwaZulu-Natal coast.
Irina caused heavy storms in KwaZulu-Natal on Saturday afternoon. On Monday the provincial co-operative governance department said about 48 families had been displaced.
"Phumaphi Makhaye, 56, broke both her legs when her house collapsed on her on Sunday morning in Jozini in the Nyawushadi area," department spokesman Vernon Mchunu said.
No other injuries were reported.
