With four months still to go in 2011, the United States has already tied its yearly record for the number of weather disasters with an economic loss of $1 billion or more, the U.S. government reported Wednesday.

With the bulk of the hurricane season ahead and winter storms after that, National Weather Service Director Jack Hayes said 2011 could surpass the record, first set in 2008.
"I don't think it takes a wizard to predict 2011 is likely to go down as one of the more extreme years for weather in history," he told journalists on a conference call.
The "new reality" is that both the frequency and the cost of extreme weather are rising, making the nation more economically vulnerable and putting more lives and livelihoods at risk, Hayes said.
The number of U.S. natural disasters has tripled in the last 20 years and 2010 was a record breaker with about 250, the NWS said, citing data from Munich Re, a company that insures insurance giants.
In the report released Wednesday, the National Climatic Data Center listed these billion-dollar events in 2011, in reverse chronological order:
- Upper Midwest flooding (Summer). Estimated losses exceed $2 billion and flooding along the Missouri and Souris Rivers continues.
- Mississippi River flooding (Spring-summer). Estimated economic loss ranges from $2-4 billion and some areas are still flooded. At least 2 deaths.
- Southern Plains/Southwest drought, heat wave, wildfires (Spring-summer). Total direct losses top $5 billion; "both direct and total economic losses will rise dramatically as the event continues," the NWS said.
- Midwest/Southeast tornadoes (May 22-27). An estimated 180 tornadoes caused 177 deaths, most in Joplin, Mo., and nearly $5 billion in insured losses. Total losses are greater than $7 billion.
- Southeast/Ohio Valley/Midwest tornadoes (April 25-30). An estimated 305 tornadoes left 327 dead and caused nearly $7 billion in insured losses. Total losses topped $9 billion.
- Midwest/Southeast tornadoes (April 14-16). An estimated 160 tornadoes killed 38 people and caused $1.4 billion in insured losses; total losses topped $2 billion.
- Southeast/Midwest tornadoes (April 8-11). An estimated 59 tornadoes caused insured losses of $1.5 billion; total losses topped $2.2 billion.
- Midwest/Southeast tornadoes (April 4-5). An estimated 46 tornadoes left 9 dead and caused more than $1.6 billion in insured losses; total losses topped $2.3 billion.
- Central/East Groundhog Day Blizzard (Jan. 29-Feb. 3). The storm was tied to 36 deaths and caused insured losses of $1.1 billion; total losses topped $2 billion.
In addition to the nine large disasters, thunderstorms in the first half of 2011 caused some $20 billion in losses, double the previous three-year average of $10 billion.
Economic losses from all severe weather so far this year have reached $35 billion, the report stated, a large amount but still small compared to a few singular disasters like Hurricane Katrina, where losses topped $100 billion.
The rising costs are due partly to demographics, Hayes said. The population is rising and there are more people and more buildings in environmentally vulnerable areas, such as coastal regions.
Asked if global warming was to blame for the rising frequency of wild weather, Hayes said that was "a research question" and that it would be difficult to link any one severe season to overall climate change.Video: Building a "weather ready" nation (on this page)
The report was issued in conjunction with a government "Weather-ready" campaign to better prepare Americans for violent weather.
In the current fiscal climate, the campaign focuses on already-budgeted items such as upgrading the weather radar system and on better coordination among existing agencies.
For example, one program aims to have rainfall forecasters work more closely with the agencies that build and maintain levees and operate flood-control canals.
The campaign was timed with the advent of what is traditionally the busiest part of the June-through-November Atlantic hurricane season.
The United States has not been hit by a hurricane in three years.
"Those are the types of things that lull people to sleep. We want people vigilant," Hayes said.
The National Hurricane Center has predicted there will be as many as 19 tropical storms this year. So far there have been seven, but none have strengthened into hurricanes.
Only one, Tropical Storm Don, came ashore in the United States but it quickly fizzled over the Texas coast without delivering the rain that is badly needed in the parched state.
