For Tuesday, July 9, 2024, this notice is intended to advise the public and local municipalities of the potential for flooding within NPCA’s jurisdiction as it relates to the Niagara Peninsula, the southeastern portion of the City of Hamilton and the eastern portion of Haldimand County.
Post-tropical storm Beryl is expected to reach the Niagara Peninsula watershed in the early morning of Wednesday July 10 and last through to Thursday July 11, bringing potentially significant precipitation.
Environment Canada is predicting that the remnants of Hurricane Beryl are forecast to merge with an upper trough that is currently over central North America, creating a highly efficient conveyer belt of moisture into Southern Ontario. Forecasted rain amounts vary from 30 mm up to over 100 mm in some isolated pockets. Rainfall is expected to last for over 24 hours, with periods of high intensity.
At the present time, local reservoirs and watercourses are near their typical summer levels. While flooding of major watercourses is not expected, the forecasted rain combined with isolated thunderstorms and long duration of this storm event is expected in urban areas, smaller creeks and tributaries as well as cause significant amounts of localized runoff. Flooding of low-lying, flood prone areas is expected.
Residents are urged to stay away from creeks and rivers, especially in the vicinity of culverts, bridges and dams. Municipalities are advised to check for debris blocking storm infrastructure.
The NPCA will continue to monitor these conditions and will issue further messages as required.

This notice is in effect until 9:00 a.m., Thursday, July 11, 2024, and will be updated as required.

What if a Flood Message is Issued for Your Area?
Take heed of the message issued.
Be prepared to follow the advice and instructions of emergency response officials.
Monitoring weather and flood conditions is a shared responsibility of Conservation Authorities, OMNR, and Environment Canada. The OMNR Surface Water Monitoring Centre in Peterborough monitors weather forecasts and water levels across the province, providing the information to Conservation Authorities. Other information is also available from Environment Canada.
Conservation Authorities and the Ontario Ministry of Natural Resources are responsible for forecasting where and when flooding is likely to occur and issuing appropriate messages. Advance warning of an impending flood allows municipalities and other government agencies to put emergency response plans into operation, and if necessary, evacuate communities.
When flooding is possible or about to occur, Conservation Authorities (or the Ministry of Natural Resources in areas where there is no Conservation Authority) issue flood messages to municipal emergency management officials and the media. The municipal officials then take action to warn local residents. Flood messages are posted on Conservation Authorities’ websites. In some watersheds, members of the public can receive flood messages directly through e-mail and/or Twitter.
