Ida expected to be among costliest hurricanes to impact US mainland; Record heat and drought conditions prompt extreme wildfire activity around the globe.

Aon has published the latest edition of its monthly Global Catastrophe Recap report. It evaluates the impact of natural disaster events worldwide during August 2021. The report highlights Hurricane Ida, which made landfall in the United States as a 150 mph Category 4 storm near Port Fourchon, Louisiana on August 29, killing at least 77 people. Ida caused extensive wind, storm surge, and inland flood damage across the Southeast before its remnants later resulted in exceptional flash flood damage and convective storm impacts in the Mid-Atlantic and Northeast on September 1.

Total direct economic losses are anticipated to reach well into the tens of billions (USD), and Ida will likely become one of the costliest US mainland hurricanes on record both on a nominal and inflation-adjusted basis. While a sizeable portion of the economic damage due to coastal and inland flooding was not expected to be insured, public and private insurance entities were still likely to have exposures into the double-digit billions (USD).

Meanwhile, a major and deadly earthquake struck the Tiburon Peninsula of Haiti on August 14, killing at least 2,207 people and injuring 12,268 others. The magnitude 7.2 tremor struck on August 14 with an epicenter 13 km (8 miles) south-southeast of Petit Trou de Nippes. The tremor left nearly 140,000 structures damaged or destroyed in the Sud, Nippes, and Grand’Anse Departments alone. Government officials unofficially estimated $3 billion in economic damage, with most losses uninsured.
