According to latest JTWC warning for TC Edna [final], issued 21:00 UTC, the system was located approximately 264 NM / 488 km south of Noumea, New Caledonia, and has tracked southward at 21 knots over the past six hours.

Recent animated infrared satellite imagery depicts weakening convection associated with the system has significantly sheared off to the southeast. A 05/16:22 UTC NOAA-18 microwave image reveals shallow convection with dry air surrounding the circulation.

The combined effects of strong vertical wind shear and cold temperature have weakened Edna.

AIRS data showed that the strongest storms associated with it were southeast of the center.

The low is expected to move to the north and the west and away from New Zealand, according to the New Zealand Met Service or NZMS. NZMS noted that high pressure located to the southeast of New Zealand is expected to push the extra-tropical low away. (GODDARD)
