A boil water alert has been issued for a number of remote communities in the Roper Gulf region as a result of Tropical Cyclone Tiffany.
in a Facebook post, NT Health said they had been advised by Power and Water Corporation that the cyclone could impact water supply.
"Bickerton Island has lost power to the water plant and the ability to chlorinate drinking water has been impacted," the post reads.
"Other communities that may be affected include Groote Eylandt, Numbulwar, Rittarangu, Ngkurr and Minyerri. This advice may be extended to other communities depending on the track of the cyclone."
"If the power goes out during the cyclone, NT Health recommends as a precaution that water for drinking, food preparation and oral hygiene be obtained from either packaged bottled water or by boiling tap water and allowing it to cool before using.
"NT Health will lift the Boil Water Alert after Power and Water Corporation confirms the water supply system is fully operational and the water is safe to drink."
Anyone who has concerns can contact the NT Health - Environmental Health Hotline during business hours, toll free on 1800 095 646.
