Le ministère des Richesses naturelles – District de North Bay avise les résidents du secteur qu’un bulletin Rapport concernant les conditions du bassin versant – Perspectives d’inondation est en vigueur pour le district jusqu’au vendredi, 2 mai 2025 à 16 h.
Les résidents du district de North Bay devraient surveiller étroitement les conditions des lacs, des rivières et des ruisseaux et faire preuve de prudence à leurs abords. Les températures printanières plus chaudes, combinées aux précipitations prévues pour vendredi et samedi, devraient avoir une incidence sur les basses terres qui ont des antécédents d’inondation. Les conditions des rives et de la glace devraient également être touchées. Veuillez informer les enfants dont vous avez la responsabilité des dangers possibles et superviser leurs activités près des cours d’eau, ainsi que celles des animaux de compagnie.
Le ministère surveille de près les conditions météorologiques et l’évolution des conditions du bassin versant. D’autres mises à jour seront diffusées, au besoin.
TECHNICAL INFORMATION
Description of Weather System
A high-pressure system is expected to move across Northeast Region Friday evening through to Saturday, which is expected to bring moderate to significant rain in the range of 10 to 25mm with additional precipitation in areas that experience thunderstorms.
The 5-day total precipitation accumulation ranges from 15 mm to 35 mm. Daytime temperatures are forecasted to range between 7-17°C, with nighttime temperatures ranging from below freezing up to 9°C.
Description of Current Conditions
Water levels across the district are within normal ranges for this time of year; however, flows in rivers, streams and creeks have increased with the recent spring weather and are expected to react accordingly to the forecasted rainfall.
Lakes and rivers in the northern reaches of the district are still frozen. Where snow and ice remain, shorelines and ice conditions are unstable.
Throughout most of the district the ground is saturated and has little capacity to absorb any moisture from runoff or rainfall. Warm temperatures and forecasted rain will accelerate snowmelt where there is snowpack remaining, increasing the amount of runoff reaching watercourses.
Significant flooding is not expected; however, rainfall, snowmelt and runoff could result in flooding in low-lying areas which have a history of flooding. A close watch of local weather forecasts, special weather statements and warning is recommended.
