Ottawa is bracing for an ice storm that could bring up to 20 mm of ice accretion, prompting school closures and flight cancellations.

The storm is projected to bring ice accretion between 10 and 20 mm, raising concerns about hazardous conditions. Temperatures are expected to hover around the freezing mark, which could lead to a transition from freezing rain to rain later in the day.

In response to the forecast, the City of Ottawa has activated its significant weather event protocols. This proactive measure aims to ensure public safety as the storm approaches.

Hydro Ottawa has stated that their crews are on standby, ready to respond safely and as quickly as possible to any outages that may arise. As a precaution, residents are encouraged to prepare for potential disruptions.

As the storm approaches, residents are advised to stay informed and take necessary precautions to ensure their safety and preparedness for the expected conditions. Details remain unconfirmed.
