Police have cordoned off two city roads this afternoon after high winds destabilised the roof of the Scottish Environment Protection Agency (SEPA) building.
Greyhope Road and Sinclair Road in Torry have both been closed off by the emergency services to ensure the safety of the public.
It is understood the roof of the SEPA building has been moving violently in the high winds of Storm Ali.
A diversion has been put in place along Baxter Street.
A police spokeswoman said the closure is likely to remain in place for several hours.
