Re: Storm Eunice
Looks like we are about to get the worst, slap bang in the Red Warning area!! Tidal surge as well, hope the Environment Agency flood gates hold on the sea front!!

Re: Storm Eunice
It will be only the northern part of the Netherlands where the storm will rage and where storm surge levels will be reached. Those barriers will be closed.
Not an abnormal situation, it would be worse - also for East England and London - with NW to NE wind with the water being pushed into the narrow Channel, the 1953 situation. There are already flood warnings for areas within 5 miles of the measuring stations ruling the Thames Barrier.
This game between wind and water is one of my meteo motivations. Tension and sensation.
[EDIT 18/2 9h00:] Orange warning now for most of the Netherlands.

Re: Storm Eunice
Storm? What storm? 31mph is highest here so far and pressure has just bottomed out at 979.9hPa. 17hPa higher than my lowest pressure.
Maybe once the centre moves east the winds will increase.

Re: Storm Eunice
Well in sunny sheltered Gorey Jersey the max gust was 36 mph @11:04, currently decreasing and the lowest pressure was 1001.7 @07:00 currently rising. It also missed us then.

Re: Storm Eunice
Yes, that's when you will get the increase - 57 mph here which is lower than anticipated, but there's an hour or so left for that to change.RayProudfoot wrote: ↑Fri 18 Feb 2022 12:45 pm Storm?

Absolute pressure values are irrelevant TBH - it's the gradient of pressure around the low that gives the strong winds. In the case of this storm and the core of strong winds crossing W-E over central parts, it's the rate at which pressure is rising to the rear of the centre that is the generation mechanism for the strong winds - and that rate of pressure rise is solely down to the strength and orientation of the jet stream miles above our heads.

Re: Storm Eunice
Freddie, I’m well aware that absolute pressure is no indication of wind strength but given the Met Office forecast a weather bomb I was expecting it to be lower.
Pressure was falling extremely rapidly for a while this morning but is now rising rapidly. Winds have picked up in the last 30 mins. I expect 40mph to be broken. Maybe the path of the low is not quite that predicted 24 hours ago.

Re: Storm Eunice
I just saw on the Dutch news that the O2 arena in London is blowing away...

Re: Storm Eunice
It split into two lows - perhaps you were between the two centres? Secondary centre formed over Northern Ireland in the small hours and is now the dominant centre at 970 hPa off the coast of E Scotland. The main centre was over SW Ireland at 0600 (974 hPa), and moved ENE, moving along the Cheshire/Shropshire border late morning, and is now approaching Hull, central pressure about the same as at 0600. My pressure bottomed out at 976.7 hPa, similar values at Harwarden and Leek. Perhaps your baro is reading a bit high?RayProudfoot wrote: ↑Fri 18 Feb 2022 1:46 pm Freddie, I’m well aware that absolute pressure is no indication of wind strength but given the Met Office forecast a weather bomb I was expecting it to be lower.

It was a weather bomb, BTW, central pressure dropped more than 30 hPa in 24 hours.

Re: Storm Eunice
Splitting may have reduced the impact up here but winds are now what I expected several hours ago. Pressure was 1003 at midnight and fell to 976 at 11:32 so 27hPa in 11.5hrs. Over twice a bomb!freddie wrote: ↑Fri 18 Feb 2022 2:11 pm It split into two lows - perhaps you were between the two centres?

Pressure matches that at Manchester airport so no worries there. 52mph recorded so near peak storm.

Re: Storm Eunice
2 miles inland from south coast here, but very sheltered location and seldom record gusts over 30mph. I got 51mph at 12:24, pressure went from 1008.1 at 20:40 last night to 988.5 at 11:00 this morning. It’s been pretty bad, but thankfully everything seems OK. Cannot imagine what 90mph gusts must be like!!! Going to be a very windy weekend right through to Monday afternoon by the looks of it.

Re: Storm Eunice
The increase in winds were forecast earlier in the week to be mid morning in your area, and it did slip by 3-4 hours - especially over the past 3/4 model runs.RayProudfoot wrote: ↑Fri 18 Feb 2022 3:02 pmSplitting may have reduced the impact up here but winds are now what I expected several hours ago.
The rise has been equally dramatic - 15 hPa in 3 hours here at one point!RayProudfoot wrote: ↑Fri 18 Feb 2022 3:02 pmPressure was 1003 at midnight and fell to 976 at 11:32 so 27hPa in 11.5hrs. Over twice a bomb!
Manchester a/p recorded 976 hPa between 11:20 and 11:50 so perhaps yours is a tad high?RayProudfoot wrote: ↑Fri 18 Feb 2022 3:02 pmPressure matches that at Manchester airport so no worries there.

Re: Storm Eunice
Which matches my 976.2 at 11:32. Remember they only report to the nearest millibar.
