The county council has confirmed this evening that all schools, libraries recycling centres, leisure centres and marinas and harbours will remain closed on Friday.
Gwynedd Council has said there is a possibility the current warning for north west Wales may be upgraded to red.
A council spokesperson said: “The Met Office has issued an amber warning for the county between 5am and 9pm tomorrow due to strong winds; there is a red alert in place in other parts of Wales with the possibility that it may become red in Gwynedd.
“Every effort will be made to collect waste and recycling. If your waste is normally collected on a Friday, put your bins out in a safe and sheltered place. If they haven’t been collected, we will make every effort to collect them in the coming days.
“Bus passengers are advised that all services may be subject to some disruption, diversion and possible cancellation at short notice due to the adverse weather.
“The combination of high winds and tides means that there is a strong possibility of coastal flooding as well as the risk of falling trees and damage to buildings.
“Gwynedd Council is working with our national and regional partners to prepare for the storm that has the potential to be the largest the area has experienced in recent years.”
