Extreme Weather 2011

A year for the record books

From extreme drought, heat waves and floods to unprecedented tornado outbreaks, hurricanes, wildfires and winter storms, a record 14 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.

NOAA forecasts, advisories, watches, warnings and community-based preparedness programs have been and will continue play an even greater role in enhancing the economy and saving lives. A Weather-Ready Nation is one in which businesses, governments and the public are armed with accurate forecasts and other critical information on which to make smart decisions to protect life and property when severe weather threatens.
