Half thinking of getting up eary and heading out to kilkee or lahinch for a lookie at the waves, reckon kilkee be imprssive seeing them crashing against the cliffs.

Try get down before 11am as top of tide will be around then and because of the full moon it should be massive and a sight not to be missed… someone said the waves might reach the 8 metre mark,

Well worth the trip down.


OOOOOPS Had to edit this because it will be low water around 11am... still should be good as the tide comes in,

Just average windy conditions here in Sligo SW. Our Monkey Puzzle trees haven't started "humming" yet Expect that they will before 9 am. Take care and be safe.

We are getting 15 degrees C on our outdoor Max/min thermometer right now and its rising!!

Met Éireann saying 110km/h gusts all day tomorrow for the midlands and east, 140km/hr in the north.

I got the impression it was going to be a minor wind factor in the north of co. dublin. well to me it seems that way for tomorrow but we'll see.

Icky Thump

the Dubs just want to be involved as usual:rolleyes:

Picking up here in Dundalk now:

Woken up by serious gusts in Galway here, sea must be very rough in the bay now.

force eleven

Gusting close on 40kts here in the midlands - but very squally. Tends to die away for a few minutes then arrive back with a vengeance. Nothing out of the ordinary, the storm we had in May was worse,but this one has yet to peak.

I received a link for the Galway Harbour Company which has an automated weather station.

Peak gust of 55 kts at 0559h. Sustained 35 kts. direction SW.

temp there peaked at 17 C around 0230h.

Meanwhile, 967 mbs at UK buoy K4 west of Irish M4, wind south 30 kts so centre a few mbs lower presumably located around 55.5N 13.0W.

Note to early readers -- hurricane force gusts likely on outer west coast soon, peak 0700-0900h -- SW 50 kts gusting 80 remains the prediction.

Deep Easterly

Gusting 56 knots at the Mullet. and 54 at Mace Head:

http://www.met.ie/latest/reports.asp

Gust speeds elsewhere generally in the range of 30-50 knots.

Mean 10 min windspeed here in Tuam 18mph, down from 20mph in the last 15 mins. Pressure 985.2 rising rapidly. Temp 12.7c / 93% RH. Heavily overcast but only light spits

Deep Easterly

Updated sea area warning from the met:

"Southwest winds will reach gale force to strong gale force in all sea areas and will reach strong gale force to storm force on Irish coasts from Valentia to Slyne Head to Fair Head today and possibly touch violent storm force between Erris Head and Malin Head this morning.
Issued at 05:00 on 12-Sep-2011 "

Those two curves are the ACTUAL temperature and dewpoint, as measured. Look at the red temperature curve and how it compares to the diagonal isotherm. If temperature were constant then the temperature curve would also slope upwards from left to right, following the isotherms, but it doesn't. It's -10°C at 500 hPa, for instance.

"There is a near constant temperature gradient up to 12000 m"

Gradient - change in the value of a quantity (as temperature, pressure, or concentration) with change in a given variable and especially per unit distance in a specified direction

<facepalm>

Reiketsu

Gusts up to 47mph here but nothing constant...

Sponge Bob

Mullet and Mace highest gusts at 7 and at 8

7 = 61 and 55 KT
8 = 60 and 58 KT

snow ghost

Anecdotally it is pretty wild here at the moment - the sea is unreal being pushed in and still rising (high tide was at 6.35), with walls of airborne horizontal spray.

Hooter23

Stormy in galway said on local radio a good few trees down around the city blocking roads

homersimpson

After a very calm start to the night the storm started to arrive around 5am

Some parts of the town have no power already

Worst of the storm is supposed to hit in the afternoon but I think it will be just after 6 this evening when the tide is high

Stay safe everyone
