DUBLIN is on full alert for serious tidal flooding amid predictions of heavy rain and strong winds.
City officials have closed floodgates along the River Dodder in the Sandymount and Ringsend areas due to fears of high seas.
According to Met Eireann, heavy rain will spread northwards tonight with some very heavy falls likely in parts of the south particularly.
Flooding is also expected in coastal areas of the south and southeast.
Lowest temperatures of 4 and 9 degrees are predicted
Met Eireann also warned that tides are set to rise substantially along parts of Dublin Bay.
Large waves along the seafront could pose difficulties for motorists on coastal roads.
As a precaution, the city council has begun preventative measures in areas that have been prone to flooding.
“High tides, combined with low atmospheric pressure and high winds over the next few days, will give rise to high sea levels and possibly large waves.
“There may be very localised wave-overtopping in parts of Sandymount and Clontarf,” the council said.
The situation will be monitored over the coming days and a stock of sandbags are on standby if required.
According to Met Eireann, we are in for some “very heavy rain” overnight.
“It will become windy too with moderate to fresh and at times gusty southeast winds which could reach gale force at times along the coast.
“The rain may lead to localised flooding and temperatures will fall to between 4C and 9C,” the Met office said.
The outlook for tomorrow is just as bleak, with a wet and windy start for most commuters.
The rain will gradually clear but it will be replaced by some very heavy and prolonged showers.
Eastern coasts will again be battered by heavy rain on Wednesday night as temperatures drop as low as 3C.
Thursday will see the arrival of thundery rainfall, although there will be some bright spells.
That night temperatures will plummet even further as winter really begins to bite.
It could hit just 1C in parts before Friday brings some respite, with brighter weather.
The weekend will remain unsettled with rain at times.
The flood warning comes just a day after researchers claimed that Ireland is heading for eight more summers of rain.
Last summer was one of the wettest and coolest in decades, according to Met Eireann.
Kieran Hickey, a geography lecturer at NUI Galway, believes that wet summers in Ireland may continue until 2020.
He bases his conjecture on research which attributes increased summer rainfall in northern Europe since the late 1990s to a warming of the north Atlantic Ocean.
“It's more likely we will have more wet summers, though that doesn't mean every summer will be wet until 2020,” he said.
