Track of TD 16W

Tropical Depression Noru (16W), located approximately 425 nm east of Misawa Air Base, Japan, has tracked northward at 19 knots over the past six hours.

The extra-tropical transition process is nearly complete and the fully exposed low level circulation (LLCC) is separating from what remains of the convection. Maximum significant wave height is 17 feet.

The mid-level cold anomaly is expanding and the warm core anomaly has been forced downwards to near to the surface. Sea surface temperatures are below the minimum values necessary to support a warm core system.

An unusually strong and poleward high pressure system that is part of a blocking pattern over the western north pacific is driving Noru into the Sea of Okhotsk. The system will be closely monitored for signs of regeneration.
