FLOOD WATCH – UPDATE #2 (Issued January 12, 2020 at 15:30, Valid until January 13, 2020)
Event precipitation fell almost entirely as rain, finishing with a light dusting of snow; we have not received any reports of freezing rain in the watershed as was forecast. The heavier rain began near midnight on Friday night and continued until early Sunday morning. The heaviest widespread rainfall periods were around noon on Saturday, and just after midnight on Saturday night.
The highest rainfall totals were recorded in the Stratford area, with gauges averaging approximately 80 mm. The southern portions of the watershed (including London and Woodstock) generally received approximately 65 mm. Most snow had melted prior to the onset of the heavier rain.
The majority of watercourses peaked this morning or are peaking early this afternoon, and remain near peak levels this afternoon. In London, the South and Main Thames River continue to rise this afternoon, and are expected to peak overnight tonight. Flows across the watershed will remain high and slowly recede throughout next week.
Peak flows in the north portion of the watershed (including the North Branch of the Thames River) were generally less than the significant event of February 2018; peak flows in the south portion of the watershed were generally similar to the flows in February 2018.
Most traditional floodplain areas across the watershed have been inundated. This standing water, combined with cold, fast-moving water and slippery banks, all create danger for watershed residents. The public is encouraged to exercise extreme caution around all local waterways. People are encouraged to keep their children and pets away from all watercourses.
The UTRCA’s flood control reservoirs at Fanshawe, Wildwood and Pittock Conservation Areas are being used to minimize flood impacts. UTRCA officials are monitoring the situation, and will report on any changing conditions if necessary.
