REMARKS:
LLCC evident on radar, continuing to track inland after crossing the coast at
03Z today.

Dvorak analysis unavailable due to system being located over land.

Recent motion has been to the SW at 10 knots. NWP guidance shows system becoming
increasingly sheared from this evening as the middle-level circulation moves
southwest more rapidly than the LLCC. Although the LLCC is expected to track
west towards the coast again mid-week, the shear and the influence of dry air
are expected to prevent redevelopment.

TC Blanche gone but can still make a reappearance ...if all goes well ..not that likely though .Lots of dry air off the coast if she crosses back to the Kimberley coast near Cape Leveque.

The cyclone has weakened into a tropical depression. The ex-tropical cyclone is expected to continue moving inland over the Kimberley.
