Western Australia's first tropical cyclone of the summer is set to hit the Kimberley coast early on Thursday morning.

Tropical Cyclone Blake brought heavy rain and gusty winds to parts of the western Kimberley over the last week and is set to make landfall around 5am on Thursday.

The cyclone has already dumped up to 170mm of rain throughout the North West, and is expected to further drench the eastern Pilbara and south west Kimberley throughout Tuesday and Wednesday.

Bureau of Meteorology spokesman James Ashley said the cyclone was currently tracking south, and was mainly expected to bring rainfall through the Kimberley area.
