During Tuesday and Wednesday northwesterly low level winds are expected over the region and a steering flow somewhat from the west due to a strengthened southern monsoon trough south of Indonesia along with the possible development of two tropical cyclone south of Java island within that monsoon trough.The Perth Tropical Cyclone Warning Center(TCWC) of the Australian Bureau of Meteorology(BOM) expects a high chance of the tropical low slightly to the northwest of Broome to develop into a tropical cyclone on Thursday with an increasing chances of the tropical low near the Cocos and Christmas Islands developing into a tropical cyclone towards the end of the week.

Medium to high chances of showers and thunderstorms are still expected then(during Tuesday and Wednesday) with the atmosphere remaining moist and unstable and the steering flow then also means a slight chance of showers and thunderstorms in the morning as showers and thunderstorms which form offshore due to land breeze convergence are steered towards the coast.

Then from Thursday the doldrums lie over the region again with light low level winds,this should also lead to a high to very high chances of showers and thunderstorms especially in the afternoon/evening but there is some uncertainty with possible dry air moving in aloft then.
