FORECAST winds of up to 40 kilometres an hour have prompted organisers to cancel Northfest 2019 at Horsham's Dudley Cornell Park.
Horsham Rural City Council took to Facebook on Friday afternoon with the news.
The free family fun day, put together by sponsors and organisations in towns, takes place every second year with the aim of enhancing connections between young people and adults.
Headspace Horsham's youth engagement and community development co-ordinator Louise Barnett said the event's committee would meet again in two weeks to consider whether to reschedule the event.
"We're just in cancellation mode at the moment," she said.
"Apologies due to weather, we didn't want anyone blowing away, and we will be in further communication about he possibility of the next Northfest."
