Just last August the federal officials who track weather disasters said 2011 would go down as a record year with 9 events topping $1 billion in damages. On Wednesday, those same authorities upped the number to 12 events — totalling $52 billion in damages —and said there’s still a chance for one or two more to be added to the list.

“In my weather career spanning four decades, I’ve never seen a year quite like 2011 … record-breaking extremes of nearly every conceivable type of weather,” National Weather Service Director Jack Hayes said in a statement accompanying the new figures.

The National Climatic Data Center said more detailed accounting led to these newcomers:

Texas, New Mexico, Arizona wildfires (Spring-summer-fall). These had been incorporated into a broader disaster category in the August report (See below under Southern Plains/Southwest drought), but were pulled out when damages exceeded $1 billion, with five deaths.
Midwest/Southeast tornadoes (June 18-22). New numbers now put damages at $1.3 billion, with three deaths from an estimated 81 twisters.
And two other events are nearing that mark:

Northeast pre-Halloween storm (Fall). This “has a 50/50 chance of exceeding $1 billion,” center forecaster Adam Smith tells msnbc.com. “It may be a stretch to indicate that this winter storm is ‘likely’ to surpass the mark. But we will have an update on this in next month’s update.”
East Coast Tropical Storm Lee (Fall). “At this point, the data suggest that the damage from Tropical Storm Lee has an unlikely (less than 50/50) chance to reach the $1 billion mark,” Smith added.
The events followed a report last August that listed 9 events topping $1 billion for the year. A few days later, Hurricane Irene hit the East Coast, causing $7.3 billion in damages, claiming 45 lives, and bringing the total to 10 events.

The old record was 9 events, set in 2008.

Moreover, the annual average has gone way up. In the 1980s, the U.S. averaged just over one weather disaster a year, the center stated. In the 1990s, the average was 3.8 a year — and that jumped to 4.6 in the 2000s and 7.5 in the past two years.

When the August report was released, Hayes called the rising frequency and cost of extreme weather a “new reality.”
