An early-spring outbreak of thunderstorms produced around 500,000 lightning strikes over Australia during the last 24 hours, with more heavy rain and flooding still to come.
A low pressure trough and low pressure system interacting with copious tropical moisture produced widespread cloud, rain and thunderstorms over Australia on Wednesday into Thursday morning.
The video below shows this volatile weather spreading over the eastern half of Australia, with lightning occurring continuously for 24 hours and still going into Thursday.

Earlier in the day, SA’s Port Augusta copped 22 mm of rain in half an hour, gaining more than its monthly average in less than 20 minutes and doubling its monthly average in under two hours.
