Warning details for UK

Yellow warning
Rain between and Show detail

Description

Heavy rain will affect Northern Ireland later on Thursday. This will fall onto saturated ground and is likely to lead to flooding in places; delayed travel may well result, including through the busy evening period. It is possible that a few properties or businesses could also be affected.

Regions and local authorities affected:

  • Northern Ireland
Northern Ireland
  • County Antrim
  • County Armagh
  • County Down
  • County Londonderry
  • County Tyrone
  • County Fermanagh

Chief Forecaster's assessment

Rain will spread into Northern Ireland on Thursday morning, turning persistent and occasionally heavy in the afternoon and lasting well into the evening before dying out. 20 to 40 mm of rain within 12 hours, (perhaps nearer 60 mm over the Mournes) falling on already very wet ground, seems likely to lead to flooding of some prone locations.

Chief Forecaster's assessment

An intense low pressure system is expected to bring a swathe of strong southwesterly winds over southern areas early on Saturday, these steadily transferring east through the morning and early afternoon, becoming westerly and eventually northwesterly later whilst also slowly easing. Gusts exceeding 50 mph are expected widely within the warning area, with gusts of around 70 mph along exposed coastal areas. These are expected to coincide with high tides, leading to locally dangerous conditions.
