    What a fascinating mess the Atlantic is right now. Unprecedented to have so many deep Low Pressure systems at one time.
    On this mornings output ECM showing higher gusts than GFS all weekend.
    ECM has been trending to overcook these storms recently so will be interesting to see if the GFS is more accurate again. Met Eireann should come out with warnings later. Heavy rain and flooding may be more of an issue with Storm Dennis.

    It looks similar to last weekend so I'd expect

    Orange Warning for Atlantic at least

    Yellow warning rainfall 20mm to 40mm

    Maybe 50 to 60mm in some location

    Wev had 82mm since last Friday and rivers in rural Sligo are burst

    This month so far must rank as one of the lowest average pressures over the Atlantic basin. I'd like to see the anomaly up to now.

    As of 11th February:

    One theory I've been following is that an increase in charged particles entering our atmosphere will lead to lower lows and higher highs caused by increased current flows in the global electric circuit. The increase being attributed to a weakening of the earths own magnetic field thus allowing in more charged particles from the sun and cosmic radiation from further afield.

    Was thinking that myself.

    All this hype with named storms has caused the connacht schools cross country races scheduled for Saturday in Loughrea to be cancelled. If you ask me it is very early to be calling this.

    Rain and flooding maybe more of a factor than the wind in that

    Flooding will have to be a factor. Ground is saturated already. Rivers still quite high, trees coming down will surely be an issue also.

    Heading towards Dunmore East last night and field near Jaybees had quite a bit of water in it. Noticed the last few days when it does rain it pools a lot more and it's taking longer for the water to drain. Anyone on flood plains would want to think about putting up some defenses if due another deluge.

    Remembering the flooding from storm frank near here

    I wonder what's the chances the record on last week's storm can be broken?
    Experts are hailing a British Airways flight as the fastest subsonic New York to London journey.

    The Boeing 747-436 reached speeds of 825 mph (1,327 km/h) as it rode a jet stream accelerated by Storm Ciara.

    Just realised that's faster than the speed of sound, so would've had some sonic booms!

    No sonic booms because it didn't break the sound "barrier ". The planes ground speed was above mach 1 but it's airspeed was well below mach 1.

    Dont think a 747 can go through the sound barrier. I think because the wind speed was so fast, it kind of carried the plane to that speed. Could be completely wrong mind you :)

    Ground speed ≠ air speed


    The air the plane was flying in was moving at a few hundred km/h, so relative to that the plane was subsonic.

    Technically yes, but actually not. The speed of sound is relative. You're only going faster than sound if you're going 1,200km/h faster than the air around you. This aircraft was travelling about 900km/h faster than the air around it, but 1,327km/h faster than the ground below it.

    While it's believed that modern aircraft could be pushed past the speed of sound, there are concerns about airframe fatigue if they were flown routinely like this, so they don't do it.

    Think of the Jet Stream like one of these in an airport... when you walk on one of these at the airport you're still walking at your normal pace, but over ground you're moving twice the speed........

    It has been fascinating seeing the momentum of the Jet over the last few weeks.!
