What Milton residents should consider

  • High humidex values today mean heat discomfort for vulnerable people; consider staying cool and hydrated, and check on elderly neighbours and pets.
  • Be prepared for gusty winds — secure outdoor furniture and items that could be blown about.
  • Thunderstorms may develop this afternoon; motorists should take care on wet roads and watch for sudden gusts or localized heavy downpours with small areas of higher rainfall (local amounts around 10 to 20 mm are possible in showers).
  • Local smoke will reduce air quality in some neighbourhoods this morning; people with respiratory conditions should limit prolonged outdoor exertion.

Monitor local conditions through municipal alerts and Environment Canada updates as the day progresses, particularly if planning outdoor activities or travel.
