Most of the southwestern United States is having a very dry winter. The northern parts of Arizona and New Mexico were clipped by a few drenching storms exiting California in December, but dry conditions are more the norm.

El Niño and La Niña can significantly alter seasonal climate conditions, such as temperature and rainfall patterns, in many parts of the world. Scientists Brad Lyon and Paul Block explain the potential impacts of La Niña in different parts of Africa.

More than half of the United States experienced heat, drought, or flooding during 2011, demonstrating the power and momentum of climate extremes.

Few winter storms and El Niño conditions brought severe drought conditions to the Hawaiian Islands this past year.

2013's Billion Dollar Weather & Climate Disasters

According to NOAA's National Climatic Data Center, the United States saw nine climate and weather disaster events, each with losses exceeding $1 billion in damages during 2013. These events included a drought event, two flooding events, and six severe storm events. Overall, these events resulted in the deaths of 113 people and had significant economic effects on the areas impacted. NCDC is the nation's scorekeeper in terms of placing extreme climate and weather events into historical perspective in this series of annual reports, dating back to 1980.

This online course will explore challenges for water management in the Western U.S. both at large and small scales.

Drought Risk Atlas

The National Drought Mitigation Center unveiled the Drought Risk Atlas on March 21. The atlas provides analysis of data on drought frequency and severity for more than 3,000 spots across the country. The stations chosen for the atlas go back at least 40 years with nearly continuous data, and some go back more than 100 years.
