Residents of southwestern New Brunswick should brace themselves for significant rainfall as Environment and Climate Change Canada has issued rainfall warnings for several regions, including Fredericton and Saint John. The wet weather is expected to arrive on Monday, March 17, 2025, bringing heavy rain estimated between 30 and 60 millimeters across various areas.
The rainfall advisory was first announced on Sunday, March 16, warning locals of potential flash flooding, localized flooding, and water pooling on roads, particularly along the Fundy Coast, where the heaviest amounts are anticipated.
According to the weather service, rain will start early Monday morning and shift slowly eastward throughout the day. “Heavy rain is expected to move from western New Brunswick and progress toward southern and central regions by Monday evening,” stated the alert from Environment Canada. “By the time the precipitation ends, the heaviest amounts are expected to be along the Fundy Coast.”
Forecasts detail specific regional weather patterns for the coming days. For example, the weather conditions for Saint John, Grand Manan, and coastal Charlotte County predict cloudy skies with light showers leading to heavier rain on Monday. Winds are expected from the south at speeds of 30 km/h, gusting to 50 km/h, with temperatures remaining cool, peaking at 7 °C.
Further inland, areas like Sussex and Fredericton will likely experience similar weather, with fluctuated temperatures from lows around 1 °C at night to highs achieving 12 °C during the day. Rainfall totals for these regions could range from 20 to 30 millimeters overnight.
Moncton and southeast New Brunswick, known for their lush landscapes, will also feel the impact of the rain. Residents should prepare for cloudy conditions with bouts of rain beginning post-noon, accompanied by potential temperatures reaching up to 14 °C. The threat of flash floods makes it imperative for residents to remain vigilant.
Unfortunately, the forecast doesn't improve immediately after Monday as weather advisories predict freezing rain conditions for the Moncton area starting Tuesday, March 18, 2025. This could result from warmer rain meeting colder temperatures, leading to ice precipitation. A special weather statement warns of possible hazards associated with this transition, urging community members to stay informed through local weather updates.
This deluge is expected to be coupled with melting snow, as other areas experience seasonal transition, making flooding scenarios more likely. The melting snow, combined with heavy rains, presents amplified challenges for communities along waterways.
Predicting weather impacts accurately is part of Environment Canada's role, and as they issue these warnings, they encourage residents to prepare. This includes checking emergency kits, ensuring vehicles are ready for adverse conditions, and staying indoors during severe weather events. By closely monitoring forecasts and following any directive issued by local authorities, residents can minimize the impact of flooding.
Prior to this significant weather change, southern areas have largely enjoyed milder weather, and this sudden shift is likely to disrupt day-to-day life. Community leaders are expected to discuss potential responses, including road closures and emergency preparedness plans to navigate the flooding conditions.
Weather forecasts remain dynamic, so it's recommended for residents to keep tabs on updates as conditions evolve. With safety as the priority, being well-informed within this rainy forecast can help mitigate risks.
While it's not uncommon for southern New Brunswick to experience heavy rainfall during this time of year, the cumulative effects of increased precipitation alongside melted snow pose substantial concerns. The community’s resilience and preparedness will be tested as the storm progresses, emphasizing the importance of staying informed and ready to respond.
