Storm Betty has brought wind and rain across Northern Ireland with flooding and fallen trees on some roads.
Police have advised drivers to be cautious on the roads as high winds and rain will make conditions difficult.
The Police Service of Northern Ireland (PSNI) urged the public to “heed any road closure signage”.
“Motorists should continue to proceed carefully and at lower speeds, bearing in mind the impact of this weather on stopping distances and braking,” a police spokeswoman said.
Road disruption
In south Belfast, a number of roads and surrounding areas have been flooded over night:
The M1 Motorway had been closed to traffic at Lisburn due to a fallen tree but has since reopened.
Translink and NI Railways said that due to “exceptional weather” there were delays and cancellations across the network.
Severe gusts and rainfall
Katesbridge in County Down had more than half a month’s worth of rain in under 12 hours overnight.
The weather station there recorded 45.4mm since 19:00 BST on Friday until 06:00 on Saturday.
The average rainfall for the entire month of August there is 84mm.
Severe gusts of wind of 90km/h (56mph) were recorded at Ballypatrick in County Antrim, while Orlock Head in County Down saw gusts of 85km/h (53mph).
The strongest gusts were recorded in the Republic with Johnstown Castle in Wexford having 96km/h (60mph) winds overnight.
Conditions will slowly improve through Saturday with sunny spells and some scattered blustery showers.
Advice and help for those affected by flooding or those who have seen a fallen tree or blocked road can be found on NI Direct’s website.
