New yellow weather warning for fog in NI

The Met Office has issued yet another weather warning, this time for fog across all six counties. 

The alert is in place from 5pm today (Wednesday) until 9am tomorrow morning (Thursday). 

Freezing fog is expected to become more extensive and thicken across Northern Ireland this evening and overnight, with visibility falling to less than 100 m in places. Once formed the fog may well persist into Thursday morning. Some icy patches will also develop on untreated surfaces bringing an additional hazard.

In Belfast this evening, thick fog is already reducing visibility in these areas in particular:

  • Westlink / M1 Broadway to J12 The Birches
  • M2 Foreshore from York Street to J2 Greencastle
What should I do? 

Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary.

Keep yourself and your family safe when it is icy. Plan to leave the house at least five minutes earlier than normal. Not needing to rush reduces your risk of accidents, slips, and falls. If you need to make a journey on foot, try to use pavements along main roads which are likely to be less slippery. Similarly, if cycling, try and stick to main roads which are more likely to have been treated.
Be prepared for weather warnings to change: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
