Storm Dennis is set to wreak havoc this weekend, but Dublin may miss the worst of it.

Met Eireann is preparing to issue weather warnings for the storm, which will pass by Ireland and bring a wet and windy day to the capital tomorrow.

Strong southerly winds and widespread heavy rain are likely to bring a risk of flooding in other counties.

Met Eireann forecaster Valerie Watters warned of the possibility of fierce winds and rain, but said the east coast would not be as badly affected as other areas.

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

"Areas in the Wicklow mountains are slightly elevated, but the rest of the east coast should be OK.

"At the moment, we're looking at heavy rain on Saturday for all parts.

"Then there will 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 Sunday night.

While the storm is currently registering pressure of just 917mb, low enough to cause extreme weather conditions, Ms Watters said that by the time it hits Ireland it will have increased to around 950mb.

Unlike when Storm Ciara hit, tides will be low this weekend, but there could still be flooding as a result of the high river levels.

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

"We're coming into a period of neap [moderate] 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."

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