Ryanair have a 30kt crosswind limit for landing when the runway is wet,and a 25kt crosswind limit for take off.
There have been no Ryanair departures from Dublin all day due to the constant strong winds,this has led to all the stands being occupied on terminal one.There was quite a long wait this morning for the three aircraft that managed to land, due to all stands being occupied at terminal one.
You get a situation where you can land but have a long wait on the taxiway while waiting for a stand to become available.
I presume that those aircraft that diverted to Shannon thought that the wind would have died down somewhat and the Ryanair's would start taking off again leaving stands free,but it seems Desmond had different plans...
