The Gulf of Alaska has cooled off considerably this autumn season and is cooler than normal for the first time since 2012. More recently, the cool waters have evolved off the U.S. West Coast. The California Ocean Current is up-welling subsurface cool waters causing a horseshoe cool anomaly to form from the Gulf of Alaska to the California Coast and southwestward toward Hawaii.

JUL/AUG/SEP 2021 was the 3rd hottest on record given the 127-year climatology and 15th wettest in that time period. Most impressive was the record wet climate during that time for New York, Massachusetts and Rhode Island.

A wet fetch out of the deep tropics interacts with a low pressure trough causing excessive rainfall forecast by GFS in the 8-14-day period across Southeast Brazil, Uruguay and northeast Argentina.

In 2013 the northeast Pacific Ocean turned extremely warm while south-southeast of Greenland the North Atlantic turned colder than normal. These conditions have been dominant since that time and affecting the North America climate more so than ENSO while also influencing the character of conventional climate signals (AO, NAO, PNA, WPO and EPO).
