What’s going on at YYZ?
 

I was supposed to be onboard a flight to YYZ right now but Delta’s telling us that there’s a ground stop at YYZ and aren’t letting planes land. I’m looking at the weather forecast and it looks like it’s not going to storm until 9 pm, four hours after our original arrival time. Does anyone have a clue what’s going on? Truly appreciate it.

Same for me...


"Severe Thunderstorm Watch in effect for Toronto. Light showers at Pearson Airport now, storms moving in."

For those unfamiliar with airport grounds-op, everything stops and the crew head for covered shelter as soon as any lightning is sighted.
Smaller planes are held at the departure airport, so there is the capacity to handle the heavies with fewer options.
