So 321 departures out of 654. The ATC report is below, but there have been an unusual number of other ATC messages about long holds in the stack (over 25 minutes, at which point some aircraft may need to divert) and take off delays. This is caused by bad weather around LHR,details below.

Landing RWY: 09L
Airborne holding (mins): 12 peak
Departure RWY: 09R
TSAT delay average (mins): 0

Heathrow: EGLLTC regulation 40/60 0540-2000z due to CB risk. End change to Westerlies anticipated between 0800-0900z but TBC.
Network: Majority of first rotation slots being generated by capacity restrictions through Germany. Hungarian restrictions also playing a part due displacement of traffic (Ukraine).

Weather: Low risk CBs LTMA 0600-0900z, medium risk 0900-2000z. High risk NW LTMA 1000-1800z. Risk of isolated gust 25-28KT in and around showers in the afternoon.
