The NI Weather & Flood Advisory Service meanwhile has also has issued an advisory of “heavy showers and thunderstorms” over the next few days.

“There is a risk that Showers & Thunderstorms could affect NI during Wednesday, Thursday but more especially on Friday this week,” it states.

“Some of these may be torrential at times with high rainfall amounts in short periods of time leading to a risk of flooding.

“At this stage there is some uncertainty in the forecast and we have held off issuing a warning.

“As always showers/thunderstorms are likely to be hit and miss with some places remaining dry throughout, although where they do occur you can expect - heavy rainfall, along with possible lightning, risk of flooding and possible localised interruptions to power supplies.”

It has been cautioned that the advisories will be updated as more data comes in.
