2011 will be remembered as the year of extreme weather . From extreme drought, heat waves  and floods to unprecedented tornado outbreaks , hurricanes , wildfires and winter storms, a record 12 weather and climate disasters in 2011 each caused $1 billion or more in damages—and most regrettably, loss of human lives and property. NOAA's National Weather Service  has redoubled its efforts to create a "Weather-Ready Nation," where vulnerable communities are better prepared for extreme weather and other natural disasters.
