After several big rain events in January, the wet season is quickly turning into one of the best on record for many parts of Western Australia's north.

Kununurra in the Kimberley had its wettest January on record, receiving just under 600 millimetres, while Fitzroy Crossing's rainfall total of 739.8 millimetres between October 1 - January 31, is the highest the town's received since records started in 1893.

A tropical low which swept across the north last week failed to turn into a cyclone, but delivered steady rain to the Kimberley and parts of the Pilbara and Gascoyne.

Lake Argyle overflowed, highways were cut and according to Glenn Cook from the weather bureau, there is more to come.

"February looks like potentially being more of the same, with the outlook suggesting most parts of WA, particularly in the Pilbara and West Kimberley region, have very strong likelihoods of seeing above-average rainfall," he said.

"The weather forecast models are even suggesting another potential low out off the coast in the next week or so.

"So it looks like more of the same in terms of that monsoonal weather that we've seen."
