Unseasonably heavy rain is affecting Western Australia's Kimberley and Pilbara regions.
Cygnet Bay in the Kimberley saw 61mm in 24 hours to Wednesday, while nearby Lombadina gained 31mm. Marble Bar received almost double its monthly average, despite only receiving 18mm. The last time Marble Bar saw this amount of rain was courtesy of Severe Tropical Cyclone Rusty in February. For Bidyadanga, the 30mm received in the last 24 hours was the highest May rainfall in 16 years.
As an offshore low continues to move east, closer to the Kimberley, moderate to heavy falls with isolated thunderstorms are expected to continue in the coming days. There is potential for coastal areas in the Kimberley to receive another 40-80mm while this system persists.
May is typically a transition time between the wet and the dry season in the tropics, where rainfall typically decreases and becomes infrequent. However, this current set-up has the potential to produce several days of rain with some residents having to wait until the weekend before seeing clear skies return. And it does not look like staying clear for long. Another system should bring more rain later on in the weekend and early next week.
This could turn out to be a wet month in some places.
