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.
