This pressure set records for many cities across the Northeastern United States for the lowest pressures ever observed. The convection diminished while the hurricane accelerated toward the New Jersey coast, and the cyclone was no longer tropical by 2100 UTC on October 29. About 2½ hours later, Sandy made landfall near Brigantine, New Jersey, with winds of 80 mph (130 km/h). During the next four days, Sandy's remnants drifted northward and then northeastward over Ontario, before merging with another low pressure area over Eastern Canada on November 2. On October 23, 2012, the path of Hurricane Sandy was correctly predicted by the European Centre for Medium-Range Weather Forecasts (ECMWF) headquartered in Reading, England nearly eight days in advance of its striking the American East Coast. The computer model noted that the storm would turn west towards land and strike the New York/New Jersey region on October 29, rather than turn east and head out to the open Atlantic as most hurricanes in this position do. By October 27, four days after the ECMWF made its prediction, the National Weather Service and National Hurricane Center confirmed the path of the hurricane predicted by the European model. The National Weather Service was criticized for not employing its higher-resolution forecast models the way that its European counterpart did. A hardware and software upgrade completed at the end of 2013 enabled the weather service to make predictions more accurate and farther in advance than the technology in 2012 had allowed. According to NCAR senior climatologist Kevin E. Trenberth, "The answer to the oft-asked question of whether an event is caused by climate change is that it is the wrong question. All weather events are affected by climate change because the environment in which they occur is warmer and moister than it used to be." Although NOAA meteorologist Martin Hoerling attributes Sandy to "little more than the coincidental alignment of a tropical storm with an extratropical storm", Trenberth does agree that the storm was caused by "natural variability" but adds that it was "enhanced by global warming". One factor contributing to the storm's strength was abnormally warm sea surface temperatures offshore the East Coast of the United States—more than above normal, to which global warming had contributed . As the temperature of the atmosphere increases, the capacity to hold water increases, leading to stronger storms and higher rainfall amounts. As they move north, Atlantic hurricanes typically are forced east and out to sea by the Prevailing Westerlies. In Sandy's case, this typical pattern was blocked by a ridge of high pressure over Greenland resulting in a negative North Atlantic Oscillation, forming a kink in the jet stream, causing it to double back on itself off the East Coast.
