Alerts and flight planning
ECCC’s Ontario alert table retrieved Monday morning showed no active land alerts. Forecast gusts, flurries and freezing temperatures still warrant attention.
Check directly with your airline before travelling to the airport. Changing winds, precipitation and visibility may affect operations; flight cancellations or delays have not been confirmed for this report.
Anyone heading onto the land should carry warm clothing, shelter and a reliable communication device. Freezing air temperatures alone do not establish that lake or river ice is safe for travel.
What to wear
A winter jacket, hat, insulated gloves and warm boots will be useful for early starts. Keep waterproof outerwear ready for Wednesday, particularly in southern inland communities and around Attawapiskat.
Watch for slippery surfaces where precipitation meets freezing temperatures.
