Flooding forecasted in the coming days/week

biko

Just a heads up folks.

Anti-flooding measures are to be deployed in the city next week to deal with some of the highest tides experienced in almost two decades.

The highest tide is expected on Sunday the 27th and could reach up to 20 foot in height – significantly higher than the Quay wall at Spanish Arch.

Lets hope the weather plays ball or it could turn rather serious.

It'll be interesting to see will the carparks in Salthill be closed off in advance of this.

The top of Blackrock diving board won't be as scary a drop. Great for beginners. :pac:

If this is the worst high tides Galway has seen in 18 years it begs the question what level of damage was done 18 years ago?

AlphaMull

I've no idea what the situation was 18 years ago in terms of damage but I don't think they are saying this event is the 'worst' tide. The are saying it's the highest in 18 years.

Lower tides but with a storm surge behind them would have caused bad flooding in more recent years.

This is how bad it got a couple times just during the last years.

I'm thinking somewhere between 5-5:30pm

Depends a lot on wind and atmospheric pressure.

Recall Debbie Hurricane in Sept 1961. Serious storm damage and flooding.

Chunks of prom torn out and left up on road.

A lot of flooding in town. At one stage almost all Dominick St flooded.

Hope weather is calm next weekend

The tide next week will come to the same height as it did at the end of August: 5.7m.

On its own, a 5.7m tide on its own is not extraordinary at all. There's a spring tide every two weeks, and the most pronounced spring tides tend to happen around the equinoxes [September and March].

If it's accompanied by low atmospheric pressure, and/or strong winds from the West, this can create a 'storm surge', potentially more than a metre higher than the predicted high tide. This can cause serious problems.

On the other hand, if it's accompanied by high atmospheric pressure, and/or strong winds from the East, then Buckfast Plaza will remain above sea level.


Here are the predicted times and heights for the spring tide beginning next weekend (27 September)
Sunday at 5.20pm: 5.5m
Monday at 5.44am: 5.5m
Monday at 6.03pm: 5.7m
Tuesday at 6.26am: 5.7m
Tuesday at 6.45pm: 5.7m
Wednesday at 7.08am: 5.6m
Wednesday at 7.29pm: 5.5m

For anyone who's interested, there is also a lunar eclipse after midnight on Sunday night. I don't know if this has any influence on tidal height, but some people may be interested in staying up to view it

Was there any flooding at all? I didn't notice anything, no high tides nor floods or anything similar.

I don't think there were any reports. I think we can count ourselves lucky though, we've had very high atmospheric pressure and relatively slack winds of late. Had we experienced more traditional poor weather (low pressure, high winds) coupled with the high tides, it would have been a very different story.

Tide was exactly as forecasted. At the Spanish arch area, the water came just as high as the top of the quay wall, but didn't go any higher.

If there had been a storm surge, the water could have come higher. There was no storm surge, (and the weather forecast showed no reason to expect one).

I'm bitterly disappointed to read in todays free paper that the council plan to leave that dreadful eyesore (the aqua-dam) in place for another month.

The spring tide on 29 October will be less pronounced than this week's non-event. They should remove the ugly aqua-dam now, and decide whether to put it up again on Monday 26 October, based on the weather forecast at that time.

Are you mad? The council working on a bank holiday!?!! What lunacy is this? :pac:

In fairness to them, for the sake of a month, it probably makes more sense to leave it in place as it's probably not cheap to use.

If they did, they'd be slammed for wasting the money when it could have stayed there for the duration

Of course a nice stone wall (over reinforced concrete) would be a permanent and more aesthetic solution for Spanish Arch area.

Quite right - I suppose it comes down to the question: how much are we prepared to spend to keep our city beautiful.

My heart sinks to think of one of the most beautiful public spaces in the country being inhabited by that great big ugly worm, all for the sake of pinching pennies while preventing flood street from maybe flooding.

Something like this would be ideal.

You need to travel more.

Ah in fairness, on a nice day the view from the Bridge of the Arches, Long Walk/across the bay is pretty iconic. Might not be THE most beautiful spot but it's definitely well photographed. 'Spaces' not so much maybe, but the whole picture is quite lovely.

No harm to leave them there because by next weekend we may have to deal with the remains of Hurricane Joaquin, should be interesting according to the posters on the weather forum it could be here by the 9th Oct.

High tide then is only 4.5m, so it's very unlikely an ex-tropical depression will cause any flooding. High swell and waves might cause problems in Salthill, but not at Spanish Arch.
