Track of TS 08S

Animated enhanced infrared satellite imagery shows Tropical Cyclone Narelle (08S)‘s low level circulation center (LLCC) remains fully exposed and detached from the main convection that is frayed and rapidly decaying. Additionally, the same animation shows a wide band of cold air stratocumulus clouds advecting from the southwest.

These recent developments indicate Narelle is now embedded in the baroclinic zone and has transformed into a cold core low. An AMSU-B radial/height cross section reveals that the warm core anomaly has disappeared, corroborating the above satellite observation. TC 08S is expected to continue accelerating southeastward deeper into the baroclinic zone.
