Conservation Authority issues flood watch for London

It will be a wet and mild Family Day weekend in the London region.

On Friday afternoon, the Upper Thames River Conservation Authority issued a flood watch bulletin, noting that warmer temperatures and rain will make for rising water levels and runoff.

The forecast is calling for a high of 0 C on Sunday but periods of rain with highs of 8 C and 9 C for Monday and Tuesday, respectively.

“Because of the amount of water already on the landscape in the form of fairly ripe snow, the lack of re-freezing temperatures forecast overnight, and three days of rain, there is the potential for a significant flood event,” said senior water resources engineer Mark Helsten.
