Former Cyclone Alessia could get a second go at roughing up the Top End, with a chance it may redevelop in the Timor Sea.
The weather bureau's tipping the low, which is now lurching about above the central Top End, will hit the Gulf of Carpentaria tomorrow, and may intensify briefly before wandering back west over the Top End on Thursday.
The bureau predicts it'll reach the Timor Sea early next week, where it may redevelop into a tropical cyclone.
The chance of it developing back into a cyclonic storm in the next three days is rated by the bureau as low - or between 5 and 20 per cent.
The Bureau of Meteorology downgraded Cyclone Alessia to a tropical low last night.
The category one cyclone hit the Northern Territory coast at 9pm last night, packing winds of up to 95 kilometres an hour around Daly River, and 70 kilometres an hour near Darwin.
More than 50 millimetres of rain fell at Adelaide River, the heaviest associated with the cyclone.
