Around parts of Co Down were worst hit. However, an amber Met Office warning was lifted as the storm eased.

Concerns have been raised about the impact the severe weather has had on certain infrastructure, such as the bridge at Quoile River in Co Down.
NIE Networks said there had been a "small number" of power cuts.
"The high winds and adverse weather brought by Storm Debi caused a low level of damage to the electricity network with some customers experiencing power cuts as a result. "Teams have been working all day to repair any damage caused and restore power as quickly as possible. "As of 4.30pm approximately 1000 customers are without power, mainly in the areas of Craigavon, Newry and Downpatrick. The aim is to have all customers restored this evening. "We would like to remind customers that if they should experience a power cut they can report the fault online at www.nienetworks.co.uk or call the NIE Networks Customer Helpline on 03457 643 643. "
