Flood Outlook: Wet Forecast this Weekend (flood bulletin, November 17-20, 2017)
Watershed Conditions Statement – Flood Outlook (Issued November 17, 2017 at 1 pm; Valid until November 20, 2017)
The Upper Thames River watershed received between 10 and 30 mm of rain from Wednesday afternoon until mid-day Thursday, with the higher amounts recorded north of Highway 7. An additional 40 – 60 mm of rain is forecast to fall beginning this evening (Friday evening), and persisting into Sunday morning.
Stream flows are responding to rain already received, and are slightly above seasonal normal levels. If the higher rainfall forecasts materialize, the UTRCA expects streams to rise further, with levels approaching top of bank in some areas. Serious flooding is not expected at this time.
Streams will likely peak late Saturday and into Sunday morning upstream of the City of London, and in downstream areas (London), late Sunday and into early Monday. There is no significant rainfall in the forecast next week.
Flood control reservoirs at Pittock, Wildwood and Fanshawe will be used to reduce downstream flooding, and are all currently at seasonal levels. Residents are reminded to use extreme caution near all watercourses, and to keep pets and children away. Water is fast moving and cold, and bank areas can be slippery.
UTRCA officials are monitoring the situation, and will report on any changing conditions if necessary.
