Fall (September-November)

  • Drought conditions intensified in north-central Oklahoma during November. Areas of extreme drought across Texas also expanded. A very active storm track across the Pacific Northwest eliminated the persistent dry conditions in parts of this region. Record amounts of precipitation fell during November. Seattle reported it's wettest month on record with 15.63 inches (397 mm) of precipitation. Parts of the Southeast also had a reprieve from the prolonged dryness in this region. For more information on drought during November, please visit the U.S. Drought page.

  • The Atlantic Hurricane Season came to an end with 9 named storms (4 tropical storms and 5 hurricanes - 2 major): a near-average season. No hurricanes made landfall along the U.S. mainland in 2006. For additional information on hurricanes in the atlantic basin in 2006, please visit the Atlantic Hurricane Season page.

  • In the East North Pacific basin, Tropical Storm Rosa and Hurricane Sergio formed. Hurricane Sergio was a strong category 2 storm and the strongest November hurricane on record in the East North Pacific basin. For the season, 19 named storms formed (8 tropical storms and 11 hurricanes - 6 major), which was above average. For additional information on hurricanes in the East North Pacific basin in 2006, please visit the East North Pacific Hurricane Season page.

  • El Niño-Southern Oscillation (ENSO) conditions remained in a warm phase (El Niño) in the tropical Pacific basin as Sea Surface Temperatures (SSTs) in the Equatorial Pacific continued to warm and expand throughout November. As of the beginning of December, SST anomalies are between 1.1°C and 1.3°C in all of the Niño regions, except for the Niño 1+2 region. El Niño conditions are expected to intensify during the next few months and will likely continue through spring 2007. For more information on ENSO conditions, please visit the NCDC ENSO Monitoring page and the latest NOAA ENSO Advisory.
