A cluster of slow moving thunderstorms that developed in a region of humid, unstable air have brought a soaking to the Darwin region, with some areas seeing their heaviest falls in months. Between 4:30am and 10:00am on Sunday morning there were 1400 lightning strikes recorded within a 30km radius of Darwin city. In the 24 hours to 9am on Sunday, Leanyer in Darwin's northern suburbs received 111mm. This is the most rain they've seen since Februrary and their highest October rainfall since records began in 1990. Pinelands had 40mm and Marrara had 42mm, the highest since March for both places. The rain was lighter in the city where just 6mm fell in the gauge, although this was still their heaviest falls so far this month. The storms had mostly moved offshore by mid morning, allowing the city to dry out during Sunday afternoon. The unstable airmass will continue to linger over the region, bringing a risk of further thunderstorms in the coming days.
