National Overview:


January For information on local temperature and precipitation records during the month of January, please visit NCDC's Extremes page.

  • Across the United States, extreme drought conditions were observed in areas of Wyoming and Nebraska, as well as northern Minnesota and parts of Texas. Exceptional drought was limited to areas of south Texas. For more information on drought during January, please visit the U.S. Drought page.

  • El Niño-Southern Oscillation (ENSO) conditions are indicative of a weak warm episode (El Niño) in the tropical Pacific basin. Sea Surface Temperatures (SSTs) in the Equatorial Pacific decreased to between 0.5°C and 1.0°C above average in most of the Niño regions. Current forecasts indicate the likely development of ENSO-neutral conditions during March - May 2007. For additional information on ENSO conditions, please visit the NCDC ENSO Monitoring page and the latest NOAA ENSO Advisory.
