REMARKS:
Ex-TC Veronica was located using Dampier radar and animated IR imagery in which
the LLCC is clearly distcernible. Confidence in the position is high.

Dvorak analysis: DT was 2.0 at 2000 UTC but is becoming difficult to assign as
the convection wekanes. MET is 2.0 and CI is held at 2.5. No gales evident on
ASCAT-C pass at 1420, and there are now no observations reading gales.

Conditions are unfavourable for redevelopment and no further bulletins will be
issued for this system.
