The government is asking people to avoid plantations and glens.
Storm Darragh battered the Island over the weekend and caused extensive damage to these areas.
The government says a full assessment of the damage in affected areas will take days to complete and is asking the public to stay away until it is complete.
It says fallen trees, unstable ground and blocked paths could create significant dangers to walkers.
