November was a wet month in many countries across the globe, with heavy rains and flooding causing billions of dollars of economic losses, according to Aon’s monthly Global Catastrophe Recap report, which each month evaluates the impact of global natural disaster events.
“The reality of heavier rainfall events and subsequent flooding continues to become more evident on a seemingly monthly basis as new examples of extreme events occur,” said Steve Bowen, managing director and head of Catastrophe Insight for Aon’s Impact Forecasting team.
He noted that 2021 has recorded several record-setting events in Europe, Asia, Oceania and the Americas, “which has further exposed structural, agricultural and infrastructure vulnerabilities to high-intensity, low-interval rainfall occurrences. Recent events in Canada, India and Australia serve as reminders of the need to navigate the increasing volatility of these events and the interconnected and more severe risks they present.”
The report reveals that an “atmospheric river” caused catastrophic impacts in Canada’s southern British Columbia province in mid-November, resulting in a province-wide state of emergency and killing four people. Damage to property, agricultural interests and infrastructure was widespread, which also resulted in notable supply chain disruptions, said the report.
The economic loss was anticipated to approach or exceed US$2 billion in Canada alone. Heavy rains also affected the U.S. state of Washington, where additional economic losses were estimated to reach US$200 million.
Notable flooding in New South Wales and Queensland in Australia occurred during the second half of November, said the report, citing significant flooding along the Upper Lachlan River, where evacuation orders were issued for residents in Forbes. This was the wettest November for New South Wales and Australia since records began, said the report, noting that extensive damage to agricultural land occurred, with total economic losses initially expected to be in the 100s of millions of dollars.
Elsewhere, an active Northeast Monsoon affected parts of India and Sri Lanka from late October through November, killing at least 190 people in India and 27 in Sri Lanka. Tens of thousands of structures and vehicles were damaged or destroyed, along with agricultural land and infrastructure.
The report said total economic losses in Karnataka and Andhra Pradesh states (India) alone were estimated at more than INR180 billion (US$2.4 billion), with additional losses in neighboring states.
