As the category one storm weakens to a low, the system is expected to bring even more rain to the sodden north-west pastoral areas of Queensland, as well as the agricultural region of the Atherton Tableland west of Cairns.

The Bureau is tracking the centre of the system to move east-south-east, in the general direction of Croydon, Georgetown and Chillagoe.

The Bureau says Charlotte is drawing strong west to northwest winds into the northern Gulf region from a very active monsoon to the north of the continent.

An official Cyclone Warning is still in place for areas between Cape Keer-Weer and Burketown.

However, coastal and island residents between the Torres Strait islands and Cape Keer-Weer are also being warned that the strong monsoon winds will continue to bring higher than normal tides, and damaging winds in monsoon squalls, with gusts up to 100 km/hr.

The Bureau says these winds have already caused sea levels to rise above the high water mark during recent high tides.

The sea is likely to rise over the high water mark again today, with damaging waves and flooding of some low lying areas close to the shoreline on the high tide.
