Widespread heavy rain reduced visibilities to less than a kilometre and there's also been a fair share of gusty winds.

Darwin was whipped by a 93 kilometre an hour gust on Saturday as Laurence (then a mere tropical low) came within 30km of the city. This was the strongest since March this year and enough to cause damage to infrastructure.

Rain was also an issue. In the last 72 hours Darwin Airport has been deluged with almost 400 millimetres as Laurence continued to deepen, the wettest December in 11 years.

Other parts of the Darwin-Daly region were rained on heavily too. Batchelor has picked up 409 millimetres so far, and Dum-In-Mirrie 272mm.

Even as far inland as Katherine got a splash, which recorded 68mm to 9am on Monday morning, the wettest since February.

Currently, Tropical Cyclone Laurence is heading southwest, its course set to make landfall over the Western Australian Kimberley district sometime tomorrow.

In the mean time it will intensify to a Category 2 cyclone and continue to bring upwards of 50 mm to the northern Kimberley and far western Darwin-Daly.
