Halloween morning was looking more like Christmas for parts of Ontario. Some areas could see up to 15 cm of snow by the time all is said and done. See what's fallen so far, and who is at risk during trick-or-treat hours.
Expected Max UV Observation:
This is today's expected maximum UV reading, taking today's weather into consideration.
- Minimal sun protection required for normal activity
- Wear sunglasses on bright days. If outside for more than one hour, cover up and use sunscreen
- Reflection off snow can nearly double UV strength. Wear sunglasses and apply sunscreen
