The 2020 version of the Bathurst 1000 Supercars event could be one of the wettest in recent years.

The 6.213 km Mount Panorama circuit is treacherous at the best of times, with its off-camber turns, high-speed straights up to 290 km/h and the ever-present danger of errant kangaroos.

The last two Bathurst 1000s were dry, as you'd expect in a period when the Central West region of NSW experienced a crippling drought. But pastures in the area are now green so it's perhaps no surprise that rain and storms are forecast for this year's great race.

You can see what's in store on the map below. A trough and cold front will cross Central West NSW late on Saturday, with a strong likelihood of rain with possible storms during the weekend.

At this stage, there is a fair chance of a wet Top Ten Shootout - which runs from 5:05 pm to 5:50 pm and determines Sunday's all-important grid positions - although the rain may arrive a little later.

Showers will stick around on Sunday, with the chance of more storms on race day in the unstable air behind the front.

If you're heading to the mountain, it'll definitely pay to pack the three B's - beer, barbie and a brolly.

But if you're watching from the couch, buckle up and enjoy the wet weather action.

While rain can play havoc with the race, it has also created some of the most dramatic action in the race's history, including 2007 when rain came late and Craig Lowndes stole his third victory (of an eventual seven) on the last lap, and the 1994 classic when Dick Johnson and John Bowe held off the then rookie Lowndes as water sprayed everywhere.

And remember, you can be a Bathurst weather guru with one touch of your phone using the Weatherzone radar. Just centre the radar over Bathurst and you'll know when to switch to wet weather tyres before the teams do!
