Flood warnings and watches remain in effect Wednesday for most of the local watersheds.
Officials with the Ausable Bayfield, Saugeen Valley, Grey-Sauble, Maitland Valley and Grand River Conservation Authorities are monitoring conditions closely.
The mild temperatures and rainfall will lead to elevated watercourse flows. Flooding is likely in low lying areas through Wednesday or Thursday.
Quite a few rural roads in Perth, Huron, Bruce and Grey counties are under water. Detours are in effect.
Despite water levels quickly rising in the Maitland watershed, Jayne Thompson, communications director for the Maitland Valley Conservation Authority, says they don't expect it to get as bad as the flood event last June.
"At the moment, we don't expect the levels to reach as high as they were at the end of June last year," said Thompson. "When we look back at our recent history, the levels should be pretty close to what we saw in 2008."
In the Grey Sauble watersheds, between 20-40 mm of rain fell over the last 24 hours and another 25 mm was expected Tuesday night. Officials say flows are currently below average spring runoff conditions but localized flooding may occur in low lying areas that typically flood or are known to be impacted by ice jamming.
In the Grand River watershed, the flood coordinator for Mapleton Township is monitoring along the Conestogo River and warn residents in the Level 1 flood zone.
