Power outages in N.S. due to heavy rain Heavy rain in the Maritimes has caused a number of power outages across Nova Scotia.

Thousands of Nova Scotians remain in the dark Saturday morning after a severe rainstorm that flooded basements, yards and roadways Friday.

CTV Atlantic’s Chief Meteorologist Kalin Mitchell estimated Friday night that between 30 and 50 millimetres of rain fell over communities from Port Mouton all the way to Fall River.

But there were many areas that saw much larger rainfall totals, with Bedford, Timberlea and Sackville exceeding 200 millimetres in a matter of just seven hours.

The severe rainfall, along with strong bursts of thunder and lightning, caused flash flooding along some roadways, leaving cars and first responders alike in dangerous positions.

Mitchell noted Friday that the rainfall totals are “almost certainly” going to break records for a July 21, with the possibility of some areas setting new highs on any day on record in July.

Late Friday evening, hours after the worst of the system passed through central Nova Scotia, an emergency alert was issued for the Halifax Regional Municipality urging drivers to avoid roadways except in the event of an emergency.
