Darwin has had its first rainfall in almost six months as the wet season finally hit the Top End.

As snow and severe thunderstorms lash the southern coast of New South Wales resulting in thousands losing power, Darwin locals could not be happier with their own dose of wildish weather.

Some people rang talkback radio or posted messages on social media.

"First rain in 5 months! I've never been this happy with rain," said one post on Twitter.

Ashley Patterson from the Bureau of Meteorology said Darwin Airport recorded 10mm of rain, with 12mm recorded at Palmerston.

Elsewhere in the Northern Territory 17mm fell at Ferguson River in the Daly District.

The Northern Territory normally experiences five storms during October.

"It is the first batch of rainfall for the wet season," Mr Patterson said.

"It is just a bit slow. It has been dry and its [the rain] has come a bit late."

The rainfall may be the first instalment with more wet weather expected in the next week.

The bureau is predicting a medium chance of rain on Thursday and a 30 per cent chance of a shower on Tuesday next week.
