Strong airflow on the outskirts of a typhoon produced a waterspout in Tamsui, New Taipei City, Taiwan.
According to a report by the Central News Agency, the phenomenon that occurred on the afternoon of August 8 lasted about 30 minutes, and some roof damage was also reported. Waterspouts are eye-catching, but they are extremely dangerous at close range.
3-Line Summary
1. A waterspout was reported in Tamsui under the influence of the outer circulation of Typhoon Baekhaedon.
2. Waterspouts are rotating phenomena produced by localized convection and changes in wind.
3. If you see one, taking shelter in a safe building or vehicle and checking official warnings take priority over filming.
What Happened
The Central News Agency (CNA) reported that a waterspout accompanied by hook-shaped clouds appeared in Tamsui on the afternoon of August 8, with the outer circulation and strong airflow of Typhoon Baekhaedon as the backdrop. The report also said it lasted about 30 minutes and caused damage to corrugated metal roofs and other structures.
Over water, a waterspout is called a waterspout; over land, it may also be described as a localized rotating wind phenomenon. Its size and duration vary, but airborne debris and wind gusts can make it dangerous at close range.
Why Does It Form?
When unstable air, updrafts, and differences in wind direction and speed overlap, the air can rotate and a vortex can develop. Strong convection and changes in wind can occur around the outer parts of a typhoon, sometimes creating conditions for such phenomena.
However, not every strong rain cloud leads to a waterspout. Because the location and timing are highly localized, it is often recognized only after it is seen.
What Should You Do If You See One?
Move away from windows and glass doors and enter a sturdy indoor space. Avoid areas with abundant airborne debris, such as open outdoor areas, coasts, and construction sites. If you are in a vehicle, pull over safely, but it is best to avoid elevated structures and areas around street trees.
Approaching a waterspout or flying a drone toward it is dangerous. If local authorities issue warnings or evacuation guidance, follow them immediately.
In Summary
The Tamsui waterspout was reported as a brief but powerful weather phenomenon produced by unstable air on the outskirts of a typhoon. The rarer the sight, the more important it is to keep your distance and prioritize safety over watching.
