UN agency says deadly floods show need for faster, wider warnings

Latest reports coming from the UN World Meteorological Organization (WMO) has shown that more intense downpours and glacier outburst floods are becoming increasingly frequent, with deadly consequences for communities caught off guard.

Stefan Uhlenbrook, WMO Director of Hydrology, Water and Cryosphere was quoted as saying that “Flash floods are not new, but their frequency and intensity are increasing in many regions due to rapid urbanization, land-use change and a changing climate,”.

Each additional degree Celsius of warming enables the air to hold about 7 per cent more water vapour.

“This is increasing the risk of more extreme rainfall events. At the same time, glacier-related flood hazards are increasing due to enhanced ice melting in a warmer climate,” he added.

Floods and flash floods claim thousands of lives each year and cause billions of dollars in damage. In 2020, severe flooding across South Asia killed more than 6,500 people and caused $105 billion in economic losses.

Two years later, catastrophic floods in Pakistan left over 1,700 people dead, 33 million affected and losses exceeding $40 billion, reversing years of development gains.

This year, the onslaught has continued. In July alone, South Asia, East Asia and the United States have seen a string of deadly events, from monsoon rains to glacial lake bursts and sudden flash floods.

In India and Pakistan, heavy monsoon rains have severed transport links, washed away homes and triggered landslides. Pakistan declared a state of emergency in its worst-hit areas, deploying military helicopters for rescue missions after forecasters warned of exceptional flood risk along the upper Jhelum River.

The Republic of Korea suffered record-breaking downpours between 16-20 July, with rainfall exceeding 115 mm per hour in some locations. At least 18 people were killed and more than 13,000 were evacuated.

In southern China, authorities issued flash flood and landslide alerts on 21 July, just a day after Typhoon Wipha battered Hong Kong, underscoring the compound risks of sequential storms.
