In a stark contrast to last year, this year's November across the Top End has been a damp one, with a soggy end also on the way. It has been remarkably wet for this early in the wet season for the region, with many places so far seeing more than three times their monthly average for November. Darwin has received 317mm for the month so far, currently the second wettest November on record and 2.5 times the monthly average. The wet conditions have also meant it has been cooler than usual, with the city a good chance to see its coolest November since 1999. Just southeast of the region in the Roper-McArthur district, it has been exceptionally wet, with places such as Centre Island and McArthur River having their wettest November's on record. For Centre Island, the monthly total of 331mm so far is almost ten times the average. While today is officially the last day rain can be counted towards the month of November, totals could rise noticeably for some places with torrential rain falling across the region in the past few days. In the 24 hours to 9am on Thursday, Adelaide River collected 102mm, its heaviest daily November fall on record. Meanwhile, Douglas River picked up 76mm to 9am today, and Wandie Creek 69mm. For Douglas River, the 217mm for the month so far is only 30mm short of the all-time November record. Further heavy falls will occur across the region today as the remnants of Ex-Tropical Alessia interact with the monsoon trough. The system will move steadily west over the coming days into the start of December, with the heaviest falls likely to be over Sunday and Monday when a further 100-to-200mm is possible in parts. From Tuesday, the system will move towards the Western Australia Coast, causing falls to ease across the region, however showers and thunderstorms will still persist with locally heavy falls possible.
