Perth has had a thundery start to the weekend, with an impressive light show and the heaviest rain in years for some places.
A low pressure trough caused thunderstorms to spark up during the early hours of Saturday, with more than 2500 lightning strikes recorded within a 150km radius of Perth between midnight and 8am.
The thundery action really picked up after 4am, bringing isolated heavy falls to some parts. The wettest part of Perth was the airport, where 39mm had landed in the gauge by 9am, making it the heaviest rain since July 2010. Elsewhere, there was 18mm at Bickley and 14mm at Whiteman Park, while the city itself had just 4mm.
As the morning progresses the rumbles of thunder will continue across the city, causing early voters to venture out in raincoats.
By Saturday afternoon, a high pressure ridge will start to build from the west, bringing more stable conditions and making further thunderstorms unlikely. So for late voters a sausage sizzle at the polling booth may still be a go-er.
