For those of you who like to listen to ATC during bad weather.
The heavy snow just started falling, and SPECIs are getting issued left right and centre. Forecasters are estimating 3cm(1.1inches)/hr.
The most interesting traffic will probably be on the CYYZ feed. CYTZ might offer some interesting traffic if the feed is working (Porter usually diverts to CYYZ if they cant land at CYTZ).
Also, you can get real time RVR information from the NavCanada Site at:
