More than 100 houses in Denpasar were damaged by whirlwinds Wednesday. Preliminary reports say that it caused no fatalities.
As of 4 p.m., the local authorities had confirmed that at least 75 houses were partially or severely damaged in one housing complex, identified as Jati Pesona estate on Jl. Pulau Moyo. The powerful winds also inflicted damage on temples, mosques and cars.
Earlier in the afternoon, Bali Disaster Mitigation Agency (BPBD) operations head I Gde Made Jaya Serataberana revealed that three locations had bore the brunt of the incident.
“We haven’t seen any severe injuries,” he said.
Panji, one of the agency’s operations team members, said that personnel in Pemogan and Pedungan reported that 50 house roofs had been damaged.
The Meteorology, Climatology and Geophysics Agency (BMKG) reported it had earlier warned agencies of a potential whirlwind at around 12:30 p.m. on Wednesday.
“The agencies should have forwarded the information to the public,” said BMKG’s data and information division head, I Nyoman Wiryajaya.
Wiryajaya explained that the public should receive alerts immediately for extreme weather, earthquakes and other natural disasters.
“We are developing an early warning system for climate-related incidents,” he said.
As of now, he said, earthquake information was accessible via the Internet and agencies could utilize this to informed.
Wiryajaya said that severe storms could occur at any time, especially during cloudy weather. Among the characteristics were the appearance of cumulonimbus (dense, towering vertical) clouds, short periods of heavy rain and thunder.
The BMKG predicted that the peak of Bali’s rainy season would be between January and February. The public must remain alert, Wiryajaya said.
Late last year, a similar whirlwind also destroyed dozens of houses and killed one person in Tabanan.
Made Astra, a weather analyst at Denpasar Geophysics Station, said the freak weather could appear when hot and cold air masses met.
The hot air on Wednesday came from Denpasar, he said.
“Right before the incident, Denpasar was 32.4 degrees Celsius. Thereafter, the cold air mass came in from the city’s southwestern area,” he said. “The meeting of these two resulted in a whirlwind around Pemogan-Pedungan-Sesetan and the areas around them.”
He explained that weather such as this normally lasted for three to five minutes and moved horizontally.
Hestri, a Pedungan resident, said she witnessed many goods, including roofs, wood and plastic bags flying about.
“Waste was everywhere,” said the printing company worker.
The picture of the tall, spiraling column of air that played havoc as it moved violently across the southern outskirts of Denpasar soon went viral across social media and instant messaging services
