Severe weather warnings have come into effect in Northern Ireland as Storm Isha arrives.
A yellow weather warning began at noon, with high winds of up to 80mph (130km/h) forecast on some coasts and gusts of between 60 and 70mph (100-115km/h) inland.
Disruption is expected and travellers have been warned to be cautious.
Flights have been cancelled at Belfast City and Dublin airports, with several diverted from Dublin on Sunday.
Belfast City Airport and Belfast International Airport warned passengers of further disruption while British Airways said it was monitoring the situation closely.
Ferry services between Larne, Belfast and Cairnryan have also been cancelled, while Monday morning sailings are “in doubt”, P&O Ferries said.

In Belfast city centre on Sunday afternoon, police advised pedestrians to avoid the Castle Lane area due to unsafe scaffolding.
Officers closed Castle Lane at its junction with Royal Avenue after member of the public was struck by falling debris. They were being treated at the scene by emergency services, the Police Service of Northern Ireland said.
As Storm Isha increases in severity an amber warning, the second highest level, comes into force from 18:00 GMT.
It will be in place until 06:00 on Monday. The yellow warning will also expire at noon on Monday.
That means there is an increased risk of power cuts, damage to buildings, travel disruption, injuries and danger to life because of large coastal waves.
The Met Office is warning of a small chance of peak winds of 90mph (145 km/h) in exposed coastal or hilly areas during this period.

It is warning of debris on roads, fallen trees, the possibility of flooding and, in coastal areas, big waves.
The department has also advised that continuing industrial action could hamper response and clean-up operations, and other DfI services in areas affected, including:
- Assistance to those incidents with most impact to life and property
- Response and clear-up operation to fallen trees and debris on the roads
- Repair of serious defects such as manhole collapse or potholes
- Gully clearing and cleansing
- Response to calls to the flood incident line
- Response to flood emergencies
The Met Office advised people to stay up to date with weather forecasts as well as advice from local authorities and emergency services.

Severe weather warnings have also been issued to parts of Great Britain, which could affect flights and ferry services between Britain and the island of Ireland.
Newry and Mourne District Council have said Castlewellan, Delamont, Kilbroney, and Slieve Gullion forest and country parks will be closed on Sunday due to the storm.
They are expected to open again from noon on Monday, subject to safety inspections.
Red alerts issued
Meanwhile in the Republic of Ireland, a number of severe weather warnings have been issued across the country for much of the day.

Severe and destructive winds are forecast, especially for coastal and exposed areas.

Storm Isha marks the ninth named storm of the season, which started on 1 September, and is the first storm beginning with the letter ‘I’ since February 2016.
It follows in the wake of Storm Henk, which wreaked havoc and caused severe damage in parts of the UK in early January.
The worst of the strong winds are expected later on Sunday
Once the storm passes there will be some relief from very strong winds until another wind warning comes into force at 16:00 on Tuesday.
It is forecast to stay in place until noon on Wednesday, with more disruption to travel and utilities expected in that period.
However, the timing of that warning could change between now and then.
