The La Nina in the Pacific is reaching its peak and is expected to become slightly weaker next year. Most parts of the equatorial Pacific except for the extreme western parts are now covered with colder sea surface temperature (SST) anomalies. Warmer than normal SST are seen in the midlatitude regions of Pacific and Atlantic Oceans and western tropical Indian Ocean.

SST anomalies for October 2007.

Particularly seas around Japan are warm which indicates a moderate winter there. However, high latitude variations and the meandiring wind patterns there might bring some cold spells to Japan. Together with a warm sea around the region sometimes would cause snow. The warmer SST in the northern North Atlantic is expected to moderate the winter temperature in Europe. Britain and Scandinavian regions are expected to receive above normal rains and snow.

The Indian Ocean conditions will favor above normal winter rains in the maritime continent. The northeast monsoon rain in western India is expected to be stronger than normal. Sri Lanka also will enjoy good rainfall and moderate temperatures.

The dry conditions in Eastern Australia are expected to recede following the changes in the conditions of Indian and Pacific Oceans. However, because of the strengthening of La Nina western USA will receive less than normal rainfall.
