Brookmans Park & Dovers Poor Wx
Last night loads of storms & CB activity both sides of LHR wreaking havoc.
Around 1730z London ATC not permitting anymore SIDs thru Dover or Brookmans Park due to high level of storm intensity and traffic volumes.
At one stage Epsom SIDs and STARS badly effected by storms.
Between 1730z and 1800z only aircraft heading on a straight track departure from LHR were allowed to depart, i.e. VS011 and BA001 OK. Storm was some 9 miles long at one stage and the cell was half a mile north of the threshold for 27R!
BA442 almost had to return to stand for more fuel as it sat awaiting a new departure track to avoid wx.
