Environment Canada is warning of a prolonged period of rain across northern Manitoba, including Thompson, beginning today and continuing through the weekend.

According to information shared by the City of Thompson, a stalled low-pressure system is expected to bring between 30 and 50 millimetres of rain by Friday morning, with another 20 to 30 millimetres possible by Sunday afternoon.

 Officials say rainfall amounts may vary, but residents should be prepared for water pooling on roads and in low-lying areas.

Drivers are encouraged to slow down during periods of heavy rain and avoid flooded sections of roadway.
