Every hPa is a difference of around 27 feet, so that difference of 26 hPa means you'd be flying 700 ft lower in 999 hPa than you would in 1025 hPa.

The saying goes "Flying from high to low, watch out below".

Thank you. Such skills needed up there. Deeply awed!

Easing pleasurably.

This is the third gale/wind -loud night in a row here.
N./NW sounds quite different from S/Sw.

Had to travel to the office in Dublin earlier in the evening. Left around 23:00. Was breezy but nothing out of the ordinary. Got back home to North Kildare about half an hour later. Wind a little stronger as I am exposed to a westerly (sheltered from most directions bar anything with "west" in it). Was windy but certainly not a gale. I'd say gusts were up to force 8 with the odd one up to force 9. Winds have eased off a good bit now. Mean speeds would be at higher end of strong breeze with gusts generally around near gale force, the odd one maybe touching gale force 8.

My nearest weather station is Dunsany (Meath) and average winds for the 00:00 report were force 5 with gusts of force 7 (high end of). It's fairly sheltered there so looking at the 01:00 reports at Dublin Airport (where it's very exposed) the average winds were touching force 7 with gusts at the high end of force 8. This Dublin report would be fairly similar to the conditions at my north Kildare location around the same time.

In short, it's a fairly typical windy late autumn strong Atlantic low scenario but the lack of stronger than average winds for the past could make it seem stronger than it is for some people.
Case in point: Across the whole country there are currently 6 ESB breakdowns showing up on the ESB Power Check website with about 400 customers in total affected. If this was an actual storm (with storm force winds), we would have dozens upon dozens of power cuts affecting thousands or tens of thousands of customers.

Not a puff of wind all day in Cork City. I was waiting all night for the wind warning only to learn that it was already over.

Petering out nicely out here but still snarling strong winds, and a bitter, winter chill biting.

East Wicklow, lost power last night (back this morning) and trees down. It seemed to be NW winds instead of the usual S or SW and this seemed to have more of an impact than some stronger winds earlier this autumn

Yes the wind direction affects differently.

Most of the houses nearest northern facing Atlantic shore here are either " back to the north", or where I live, gable end to the north ( built 150 years ago many of them. )

What they call " vernacular architecture"

They even(!) set the chimneys for the prevailing winds. Getting the stove to light in a northerly....
Because although most of the winds are s/sw, when the northerlies come in they are stronger and fiercer. And colder...

Wish I could measure wind speeds out here .
