This year's heaviest tropical storm is pushing a wide arc of water and wind across East Asia, leaving a torn trail in its wake. As in eastern Taiwan, entire villages were raided after a reservoir breached and rescue services are still searching for missing people while Hong Kong closed its shutters and airlines fanned entire fleets to avoid damage and southern China is gearing up for new hits along the Guangdong coast.
On Taiwan, residents of Hualien tell how water and mud turned streets into churning gullies in an instant after a natural dam gave way, resulting in deaths and a large number of missing persons, and with teams searching on foot and by helicopter as soon as winds allowed. The national fire department speaks of an extraordinary situation fueled by days of rain that unexpectedly put entire communities in the dark.
On the other side, Hong Kong opted for maximum precaution, the highest storm warning was rigged and public life came to a virtual standstill, airports pushed hundreds of flights off the board and major carriers moved most of their planes to safer fields in the region, while overflowing seawater plagued boulevards and the stock market remained open but running on a skeleton staff. The airport, normally a world hub for cargo, halted traffic for extended periods to spare staff and equipment.
In mainland China, authorities along the coast are working on a massive prevention operation, with shelters opening and evacuations running into the millions in the densely populated belt from Shenzhen to farther west, where the storm field is coming ashore with hurricane force winds and heavy rain that could linger for days in lowlands and river deltas. Weather officials are warning of significant storm surge that will raise water gauges in bays and estuaries.
All this fits a familiar pattern in which the greatest damage comes not only from the wind but especially from the water that continues to surge after passage, as dam breaches, landslides and secondary flooding make rescue work slow and treacherous. A lesson that recurs every time a category five system grazes the edge of the continent and then rains out inland. Photo reports show boardwalks where waves pound above light poles and wharves disappearing in foam as traffic stalls and power falters.
Still, for countries with long rivers and vast forest and clay areas far from this storm, there is a quiet clue in this story, namely that the heaviest costs are often avoided by dull preparatory work. Think maps that show risk zones down to village level, monitoring points that transmit in real time and emergency scenarios that practice every rain day, because that's when evacuation paths prove passable, levees and locks closed in time and communications clear enough that people act without panic. The region shows how speed, discipline and redundancy save lives, even when nature takes a turn for the worse.
