With severe winter weather scheduled to slam into the east coast on Thursday and Friday, some airlines are warning of delayed or cancelled flights.
A winter storm warning has been issued for much of Atlantic Canada and parts of the eastern United States with snow expected to start falling Thursday morning.
Pearson International Airport is asking anyone flying to the east coast to check your flight status with your airline before arriving at the airport.
Winter weather and cold temperatures are in the forecast and may impact flight schedules. As always, please check your flight status with your airline or at https://t.co/sCj5fDvHJ1

Delta Airlines has proactively cancelled more than 400 flights as of Wednesday evening and into Thursday, primarily at JFK and LaGuardia airports in New York and Boston’s Logan International.
This same weather system forced Delta to suspend operations at Savannah/Hilton Head International Airport in Georgia due to snow and ice accumulation on runways and taxiways.
The system hitting the east coast has been described as a “bomb cyclone.” But as fearsome as the storm is with high winds and some snow, it may not be quite as explosive as the term sounds.
“Bombogenesis is the technical term. Bomb cyclone is a shortened version of it, better for social media,” said Weather.US meteorologist Ryan Maue, who helped popularize the term polar vortex in 2014.
“The actual impacts aren’t going to be a bomb at all,” Maue said. “There’s nothing exploding or detonating.”
Bomb cyclones draw air from polar regions after they leave. In this case, it means extra cold Arctic air because of where the polar vortex is
Storm intensity is measured by central pressure – the lower the pressure, the stronger. A storm is considered a “bomb” when the pressure drops rapidly – at least 24 millibars in 24 hours.
This storm looks like it will intensify at twice that rate, said Bob Oravec, lead forecaster at the National Weather Service’s Weather Prediction Center.
While the worst of this storm will stay out at sea, high winds with gusts approaching 100 km/h and the bitter cold that follows will be the real culprits.
