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, late on Saturday afternoon and overnight into Sunday as Narelle approaches from the east.
DESTRUCTIVE WIND GUSTS to 160 km/h are possible from south of Nhulunby to Nathan River on Saturday night or Sunday morning depending on the movement of Narelle.

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 and evening.
