Munich Re: 2011 Breaks Annual Catastrophe Loss Record

The Munich Re insurance company announced today that the first 6 months of 2011 have already broken the record for annual catastrophe losses worldwide:
An exceptional accumulation of very severe natural catastrophes makes 2011 the highest-ever loss year on record, even after the first half-year. Already, the approx. US$ 265bn in economic losses up to the end of June easily exceeds the total figure for 2005, previously the costliest year to date (US$ 220bn for the year as a whole). Most of the losses were caused by the earthquake in Japan on 11 March.

Altogether, the loss amount was more than five times higher than the first-half average for the past ten years. The insured losses, around US$ 60bn, were also nearly five times greater than the average since 2001. First-half losses are generally lower than second-half losses, which are often affected by hurricanes in the North Atlantic and typhoons in the Northwest Pacific. The total number of loss-relevant natural events in the first six months of 2011 was 355, somewhat below the average for the previous ten years (390).
The Japanese earthquake losses were estimated at $210 billion.

Massive Thunderstorms Hit Chicago With Hurricane-Force Winds, Worst Power Outage in History

Images (click to enlarge): Northern Illinois regional radar and mid-atmosphere wind pattern at 8 am CDT, July 11, 2011, from National Weather Service; Chicago firefighters working to rescue driver trapped by fallen tree, from Chicago Sun-Times

July 11 Update: About 350,000 remained without power in Chicago as of Tuesday morning. The peak outage estimate was revised upward to 868,000.

Original post:
A line of severe thunderstorms brought hurricane-force winds to the Chicago area Monday morning, July 11. Although no tornadoes were reported, the extremely strong straight-line winds produced widespread power outages. At the peak, over 817,000 customers were without electricity. Commonwealth Edison reported that this was the largest outage from any storm in Chicago history.

The force of the wind moving eastward across southern Lake Michigan prompted a seiche and lakeshore flood warning as water levels oscillated rapidly by over 2 feet.

Trained spotters reported wind gusts as high as 80 mph. Wind gusts of 75 mph were measured at Midway Airport and 63 mph at O'Hare. Here are some selected reports from the National Weather Service:
