SIX NATIONS – Warmer temperatures and light rain spread across the Grand River watershed on the evening of Monday, Jan. 2nd. Temperatures are forecast to rise to four degrees this morning and remain above freezing until Wednesday, when more seasonable weather returns.
The current forecast call for 10 to 15 millimetres of rainfall on Tuesday afternoon throughout southern portions of the watershed. Areas to the north are forecast to receive this precipitation in the form of snow or freezing rain.
Much of the rain should be absorbed into the snow pack and snowmelt should be gradual given the short duration of above-freezing temperatures. This event should not produce a large volume of runoff, therefore stream and river levels are not expected to cause flooding. Stream and river levels will rise today and remain high through the remainder of the week and into the weekend.
Conditions will be monitored as this weather system moves through the watershed. This message is in effect until Monday, Jan. 9 unless updated messages are issued.
The public is reminded to exercise extreme caution around all water bodies. Banks adjacent to rivers and creeks are very slippery at this time and when combined with the expected weather conditions, pose a serious hazard. Parents are encouraged to keep their children and pets away from all watercourses and off frozen water bodies, which may be weakened as a result of the warming trend.
For more information on flows, weather and reservoir conditions see the River Data section of the Grand River Conservation Authority (GRCA) website.
