A number of weather warnings remained in place on Sunday morning, with strong southwest winds, severe gusts and coastal gales persisting.

ESB Networks said around 41,000 homes, farms and businesses, mostly in the northwest region, were without electricity on Sunday morning as a result of Storm Boelo.
Its PowerCheck service was showing a large number of outages in the west and northwest, as well as in parts of the midlands, Bantry in Co Cork and Dingle in Co Kerry.
“As Met Éireann weather warnings remain in place, there may be further power outages this morning,” it said.
“ESB Networks crews have been deployed since first light in all impacted areas to continue to carry out the necessary restoration work where safe to do so. We expect the vast majority of impacted customers to have their supply restored by this evening.”
In Northern Ireland, some 7,000 customers were without power as of 10.30am on Sunday, according to NIE Networks.
NIE Networks said the storm had resulted in “a level of damage to the electricity network” across Northern Ireland and incident centres to co-ordinate the response had been operational across the North since Saturday afternoon.
“Our engineers and field teams were mobilised in advance of the storm and are continuing to respond across the network, working safely and efficiently to repair damage and restore supplies to affected customers as quickly as possible,” NIE Networks said.
The Police Service of Northern Ireland (PSNI) has warned of road closures throughout Northern Ireland due to fallen trees caused by Storm Boelo.
The PSNI said a number of roads blocked by fallen trees and debris related to the weather had been cleared.
However, the Springwell Road in Groomsport remained closed and the Cootehall Road in Crawfordsburn had been reduced to one lane. The Foyle Bridge in Derry was closed due to high winds.
“Please continue to exercise caution while driving,” the force said. “If travel is essential, leave extra time for your journey and increase your stopping distance from the car in front.”
Mayo County Council said the R331 Claremorris to Ballinrobe road was partially blocked by fallen trees, with crews attending the scene to remove the obstructions.
The stormy weather caused some transport disruption, with a number of flights cancelled at Dublin Airport on Saturday and several ferry crossings not departing between Dublin and Holyhead.
Thousands of people are participating in the Dublin Marathon on Sunday morning, with organisers advising them to bring suitable layers to keep warm before the start and to have “warm, dry clothing available after finishing”.
