Heavy rainfall expected for Lanark

Environment Canada forecasters are predicting potential heavy rainfall in parts of central and eastern Ontario, including communities in Lanark County, as the remnants of Hurricane Beryl approach on Wednesday and Thursday.

Forecasters are warning of localized rainfall amounts ranging from 25 to 50 mm, anticipated to begin on Wednesday morning or afternoon and diminish by Thursday.

Dalhousie Lake water levels are expected to reach spring flood conditions. Levels are expected to increase 20 to 25 cm above current elevations should the rain forecasted for tomorrow materialize.

Water levels on Mississippi Lake are also expected to increase 15 to 20 cm above current levels based on current forecasted conditions. Levels on the upper lakes have been holding steady or dropping slowly over the last week but are expected to begin to increase again should the forecasted rain occur.

Residents in flood-prone areas are advised to maintain close watch on water levels and flows and take the necessary precautions to protect their property by ensuring sump pumps are clear, in good working condition, and have a backwater valve and ensuring that downspouts are clear and the outlet is at least three meters from any structure.

•Residents should move or secure items that might float away if flows increase.

Residents should also ensure they have a portable generator and backup pump available, if possible.

Finally, residents are advised to • keep emergency phone numbers handy and familiarize themselves with their municipality’s emergency preparedness plan. 

The heaviest rain is currently forecasted to affect areas south of the region where rainfall warnings have been issued. However, if the weather system shifts northward, additional warnings may be necessary.
