Darwin is on track to reach their December average rainfall, which is already sitting at the halfway mark. Storms on Friday morning brought an additional 34mm to the December rainfall tally, which now sits at 123mm. While the storm was short-lived, it was intense, producing 20mm in ten minutes. For the year, Darwin has seen over 2140mm hit the rain gauge so far, compared to the 987mm total to this day last year. Although, as some residents will remember, the second half of December 2016 was very soggy, with over 360mm falling in the final fortnight. Over the next week, an unstable airmass will reside over the western Top End, bringing showers and thunderstorms every day this week.
