The Return of El NiÃ±o
Anomalies in sea surface temperatures have led NOAA scientists to believe that El NiÃ±o will make a comeback this winter. In an unscheduled advisory announced on Sept. 13, NOAA scientists reported that El NiÃ±o conditions have developed in the tropical Pacific Ocean and are expected to continue into early 2007. According to Vernon Kousky, NOAA's lead El NiÃ±o forecaster, "Currently weak El NiÃ±o conditions exist, but there is potential for this event to strengthen..."
According to scientists at NOAA, these El NiÃ±o conditions may explain why Atlantic hurricanes have been less active than previously expected.
NOAA predicts that during the upcoming winter North America will experience warmer than average temperatures over western and central Canada and over the western and northern U.S. Wetter than average conditions are predicted for Florida and the Gulf Coast, drier than average for the Ohio Valley and the Pacific Northwest.
