A flood watch remains in effect for the fourth consecutive day along the Bow River, with a high river flow advisory issued as water levels continue to rise. The yellow rainfall warning, initially declared over the weekend, was still active on Monday, prompting residents and officials to monitor the situation closely.
Rainfall and Wind Gusts Persist
Environment Canada meteorologist Christy Climenhaga reported that rain is expected to continue across Calgary, with some relief anticipated by Wednesday. A low-pressure system is drawing moisture into Alberta, resulting in heavy downpours. The yellow rainfall advisory for the city remains in effect.
Precipitation amounts vary significantly across the region. At the Calgary airport, 27.8 mm of rain fell over the past 48 hours, while Springbank recorded 42 mm. Areas south of Calgary, such as Staveley, saw up to 100 mm. Over the next few days, some parts of the city could receive between 20 to 60 mm of rain.
June typically brings 112.7 mm of rain to Calgary, according to Climenhaga. In addition to the rain, the city is experiencing strong wind gusts, with peak speeds reaching 80 km/h over the last 24 hours. These winds are expected to persist until Tuesday night.
River Flow and Boating Advisory
The Calgary Fire Department has maintained a boating advisory issued on Friday. The threshold for the flow rate on the Bow River is 280 cubic metres per second, but the latest measurement recorded 360 cubic metres per second. Public information officer Alex Kwan stated that the flow rate is expected to peak at over 400 cubic metres per second on Tuesday.
Kwan emphasized that it is not safe for people to be on either the Bow or Elbow River. The boating advisory will remain in effect as conditions are hazardous.
Weather-Related Incidents and Safety Tips
The fire department has seen an increase in weather-related calls, including downed power lines and trees. Kwan advised homeowners to ensure downspouts are directed away from their homes to prevent water damage. Residents should be vigilant for arcing power lines or trees falling onto homes, roadways, or structures, and call 9-1-1 if such hazards are observed.
For those traveling, Kwan recommended planning routes in advance, avoiding flooded roadways, and staying aware of changing conditions. The city continues to monitor the situation as the rainy weather persists.
