ADVICE TO THE PUBLIC:
Category 2, sustained winds near the centre of 95 kilometres per hour with wind gusts to 130 kilometres per hour.
Location
Within 30 kilometres of 13.4 degrees South, 141.8 degrees East, 10 kilometres east southeast of Aurukun and 580 kilometres east of Alyangula.
Movement
West at 16 kilometres per hour. Tropical Cyclone Narelle is moving westwards, near Aurukun, on the western Cape York Peninsula where impacts are expected over the next few hours. Narelle is then forecast to move quickly through the Gulf of Carpentaria overnight and through Saturday, strengthening again to a severe tropical cyclone.
Narelle is expected to approach the northeast parts the Northern Territory during Saturday. It is forecast to cross the eastern Top End coast overnight Saturday or early Sunday morning, most likely between Birany Birany and Ngukurr, as a severe tropical cyclone. Narelle will then weaken as it moves inland across the Top End on Sunday and Monday.
Hazards
VERY DESTRUCTIVE WINDS with gusts to 195 km/h are forecast to develop in coastal areas between about Birany Birany and Numbulwar, including Groote Eylandt, Saturday evening and overnight into Sunday as Narelle approaches from the east.
DESTRUCTIVE WIND GUSTS to 160 km/h are forecast to develop between Birany Birany and Numbulwar, including Groote Eylandt from later Saturday afternoon and possibly extending to be between south of Nhulunbuy to Nathan River overnight Saturday or Sunday morning depending on the movement of Narelle.
GALES with DAMAGING WIND GUSTS to 120 km/h are forecast to develop in coastal and adjacent inland areas between Gapuwiyak and Port McArthur, including Nhulunbuy and Borroloola, from Saturday afternoon and overnight into Sunday. These GALES may extend west to Ramingining, Bulman, and Ngukurr on Sunday.
HEAVY RAINFALL which may lead to FLASH FLOODING is likely to develop for coastal and adjacent inland areas over the eastern Top End between Port McArthur and south of Nhulunbuy from Saturday afternoon.
LOCALLY INTENSE RAINFALL leading to DANGEROUS AND LIFE-THREATENING FLASH FLOODING is likely over the eastern Top End between Numbulwar and Birany Birany, including Groote Eylandt, during Saturday afternoon and evening
Tides will be higher than normal between Nhulunbuy and Port McArthur later Saturday and Sunday.
LARGE WAVES may produce MINOR FLOODING of low-lying coastal areas. A potentially DANGEROUS STORM TIDE between Alyangula and Port Roper is possible as the cyclone centre crosses the coast with DAMAGING WAVES and DANGEROUS FLOODING.
