Forget the dry season, the stormy wet season is fast approaching the Top End of the Northern Territory. Thunderstorm activity has increased very gradually over the last month, with instability on the rise, moisture feeding in from the northeast and heat building over the interior. During Tuesday, storms fired up near Tennant Creek, and should die down by late evening. Thunder and lightning were also making an appearance in northwest. Cape Fourcroy, the western-most point of Bathurst Island, saw thundery deluges start as early as 1pm. So far it has received almost its entire monthly average in a few hours, a total of 53 millimetres. This is the wettest it's been since December of last year, and also the wettest October day in four years. Storms may impact Darwin this afternoon and evening, with major storm activity moving to western parts of the Territory by tomorrow. With November not far off, the month that some designate as the official start of the wet season, thunderstorm events will continue to multiply, periodically illuminating the wonderful landscape that is northern Australia.
