*************************
Special weather statement in effect for:

  • Newmarket - Georgina - Northern York Region
  • Pickering - Oshawa - Southern Durham Region
  • Uxbridge - Beaverton - Northern Durham Region
  • Vaughan - Richmond Hill - Markham

Isolated thunderstorms possible this afternoon into this evening.

Several rounds of showers will move through the area this afternoon and this evening bringing general rainfall amounts of 10 mm. However, embedded isolated thunderstorms may boost local rainfall totals into the 15 to 25 mm range by late this evening.

The ground is still frozen or snow covered, so these local rainfall amounts combined with mild temperatures may cause significant snowmelt or runoff leading to localized ponding on streets and other low lying areas.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@canada.ca or tweet reports using #ONStorm.
