In addition to supply chain disruptions caused by the Japanese earthquake and flooding in Thailand, the U.S. was wracked by regional droughts, hurricanes, tornadoes, tropical storms and floods in 2011. Domestic weather events added up to 14 disasters, defined as those with economic impact greater than $1 billion, according to a report by the National Oceanic and Atmospheric Administration (NOAA.) The record-breaking string of disasters interrupted inbound and outbound transportation and rates in the affected regions, but only for brief periods.
Here is the NOAA list in brief. (For full details, including photos, videos and weather maps see http://www.noaa.gov/extreme2011/.)

The Road Ahead: FMCSA Recommends Training and Analysis
Long-term weather forecasts are notoriously unreliable, so it's best to be prepared for anything.The FMCSA issued a timely report in April on the topic of "Weather and Climate Impacts on Commercial Motor Vehicle Safety." Safety has improved enormously in recent years, according to the report, due to a variety of technological improvements in vehicles, equipment, roads and communications, as well as improved decision-making on routes and schedules. The agency recommends additional driver training and more analysis of crash data to prevent future weather-related accidents.
The American Trucking Associations also offered guidance to motorists for coping with bad weather. The rules are written for drivers of small private vehicles, but professional drivers can share them with friends and family members to keep everyone safer.
