The Met Office has warned Storm Floris will bring gusts of up to 50mph widely across the country, with up to 70mph winds in some places.
As a result, several flights arriving into Belfast City Airport have been cancelled, including the 9.15am Edinburgh flight, the 9.40am from Leeds Bradford and the 9.50am from Birmingham.
This morning TrafficWatch NI also confirmed due to wind speeds there is now a ban on high sided vehicles from using the Foyle Bridge in Londonderry.
A yellow warning for wind is set to conclude at midnight on Monday. It had initially been due to end at 6am on Tuesday.
Floris is the first storm to hit the UK and Ireland since Storm Eowyn in January, which sparked a rare red warning here.
The Met Office said: “Storm Floris will bring a spell of unusually windy weather for the time of year across the northern half of the UK on Monday.
“The highest winds are expected across Scotland between late morning and early evening. In some areas high winds will be accompanied by heavy rain. Wind will then slowly start to ease from the west later.
“Across the warning area, many inland areas are likely to see gusts of 40 to 50 mph with 60 to 70 mph possible along exposed coasts and high ground, especially Scotland.”
