SINGAPORE, May 2 — An “unusual” natural phenomenon caused debris to fly in the air at a Changi East construction site on Sunday (April 30), a Changi Airport Group (CAG) spokesperson said.

In response to TODAY’s queries, the CAG spokesperson said today that no one sustained injuries during the incident on Sunday morning at the construction site, which includes the site for Changi Airport Terminal 5 (T5).

The spokesperson was unable to specify if the affected site was the T5 construction site.

“Our contractors have since secured the movable items with additional support and works at the site have resumed following a safety assessment,” the spokesperson added.

A clip posted on TikTok by user “yeothuang1968” on Sunday showed pieces of debris flying in the air at the construction site amid strong, gusty winds. The site also includes an upcoming Changi East industrial zone.

Another online user “Amin Aziz” reposted the clip on YouTube, which lasted about four minutes, calling the weather phenomenon a “tornado”.

Some users commenting on the videos claimed that it was a waterspout rather than a tornado.

TODAY has asked the Meteorological Service Singapore about the event.
