Met Éireann have issued two nationwide Status Yellow weather warnings with Storm Dennis to wreak havoc this weekend.

The storm, which will pass by Ireland from Iceland, will bring a wet and windy day tomorrow with strong southerly winds and widespread heavy rain bringing a risk of flooding.

There is a Status Yellow rain warning in place across the country from 6am until 9pm on Saturday. There is also a Status Yellow wind warning nationwide from 3am until 8pm on Saturday.

Valerie Watters, a forecaster for the meteorological service, warned of the possibility of heavy wind and rain.

"There is a possibility that there will be wind warnings and rainfall warnings for periods over the weekend," she said.

"At the moment we're looking at heavy rain on Saturday for all parts. It will clear to showers for a while tomorrow afternoon but then there'll be another band of rain pushing in from the south in the evening, and it will be widespread overnight on Saturday.

"So there will be a good bit of rain on Saturday and there is a risk of flooding especially where water levels are already high."

Coastal areas of Connacht and Munster especially can expect up to 70mm of rain between today and Monday morning.

The rest of the country will also experience heavy rain with falls of between 30mm and 40mm, some of it falling as sleet or snow tomorrow and on Sunday night.

While the storm is currently registering pressure of just 917mb - low enough to bring extreme weather conditions, - Ms Watters said that by the time it hits Ireland, it will have increased to around 950mb, which is still low enough for gale-force winds.

Unlike when Storm Ciara hit, tides will be low this weekend; however, because of high river levels there could still be some flooding.

"The core of it will be around 917mb but that could change between now and then," Ms Watters said.

"It is a huge storm at that stage but it will have filled in by the time it gets to us and it's looking like around 950mb so we won't see such low pressure.

"We're coming into a period of neap tides, so it's not like Storm Ciara where there were high tides but there could still be some flooding because river levels are elevated and there will be lots of rain."

Ms Watters advised the public to keep an eye on any weather warnings and avoid the sea, where waves will be around 10 metres high.
