“Eleven people died in several of the sultanate’s provinces when their vehicles were swept by heavy rains as they drove through valleys,” state news agency ONA quoted a police statement as saying.
Four bodies, including those of a six-year-old and a 10-year-old, were found on Thursday. One body was found on Wednesday while the remaining five were recovered Tuesday, when the storm began.
The police issued a warning urging “maximum caution.”
The storm has likely caused at least $50 million worth of damage, officials said on Thursday.
The storm flooded many parts of the country, prompting 60 patients to be evacuated from two hospitals by government helicopters.
The two hospitals had to be closed.
“My estimate is that it will cost no less than 20 million rials ($50 million) to put them right,” a doctor said.
Witnesses said cars were swept away as rainwater flooded major motorways. Some drivers scrambled to the rooftops of their cars to escape the rising water.
The meteorological office said the storm would continue until Saturday.
In June 2010, 16 people were killed when a Cyclone Phet hit the Gulf state.
In 2007, Cyclone Gonu tore through Oman, killing at least 49 people and causing damage estimated at $3.9 billion.
