A warning has been issued for heavy and persistent rain for Northern Ireland on Wednesday.

A Met Office yellow rainfall alert has been issued from 02:00 until 21:00 BST for all counties, but eastern areas are expected to bear the brunt of downpours.

Many areas will see between 20-30mm of rain while higher areas of counties Antrim and Down could get up to 60mm.

The heaviest rain is expected through Wednesday morning and afternoon, with conditions gradually easing from the west by the evening.

This could be enough to cause some travel disruption due to spot flooding and surface spray.

The Met Office has warned of the possibility of a few homes and business being flooded, as well as possible interruptions to power supplies.
