Heavy rains and strong winds have lashed parts of Western Australia's far north after a tropical monsoon crossed over the Kimberley coast, while another low hovers to the north-west of the state.

The tropical low moved rapidly overnight, over an area encompassing Kuri Bay to the Northern Territory border, and south to Halls Creek.

It now lies east of the WA-NT border.

The low dumped more than 138 millimetres of rain on Wyndham, while Kalumburu has received more than 100 millimetres since 9:00am Tuesday.

In Kununurra, 57 millimetres fell in that period, while the town has also been hit with gusty winds of up to 70 kilometres per hour this morning.

Pilbara system to intensify this afternoon

Meanwhile, residents along WA's Pilbara coast are being urged to prepare as a second low approaching the coast is expected to intensify into a cyclone later today.

The weather system is 800 kilometres north-west of Port Hedland and tracking slowly south-west.

The low, which would be named Tropical Cyclone Yvette ones it intensifies, is not expected to hit the mainland until some time on the weekend.

To all the people living in the effected area's,  We wish you well, stay safe and survive,
