The village of Fort Simpson has issued a 48-hour precautionary flood warning for residents that live on the island. The notice was triggered after movement by the ice crossing early Monday morning.

"Breakup is imminent and residents should be prepared for potential flooding," reads the public notice. Residents can find updates on the village's page, where there is further information about the community's flood plan and current water levels.

An earlier notice reported that the Liard river had moved by the ice-crossing, which caused the Mackenzie river to move as well. As of noon on Monday, both rivers were stationary after traveling about 100 meters.

At the time of the notice, water levels reached just over 7 meters high. According to the community's flood procedures, 24-hour monitoring isn't triggered until water reaches 12.5 meters, with business and school closures beginning at 14.0 meters.

'It's got a life of its own'

Bob Norwegian lives along the riverbank on the island in Fort Simpson. He's an Elder and knowledge holder from the community who has been watching the rivers and how they behave for years.

He said it's hard to predict when exactly the rivers will break and what risk it may pose to the community.

"It's got a life of its own and you gotta bend with it," he told CBC.

It's also unclear how cold weather and snowfall sweeping the region will affect spring breakup, but it doesn't appear to be a negative development.

Roger Pilling, a former hydrologist who is currently working with the Emergency Measures Organization (EMO), said that the situation is so far developing as it would in previous years.

Typically, breakup will begin in Fort Simpson around the first week of May, but that can vary year to year, especially during cooler or warmer years. While there has been snowfall in the area over the past few days, it's likely to melt quickly with the sun expected to come out on Monday afternoon.

"I don't think the cold weather is going to hurt us," said Pilling, but he acknowledged that it's hard to know for sure as they are many variables at play.

As of right now, it's difficult to predict what will happen in the coming days, but Pilling said residents should remain prepared and vigilant.
