A low pressure system moved into the Maritimes today bringing up to 40 mm of rain to Greater Moncton.
A strong thunderstorm also rolled through Southeast New Brunswick in the early evening with wind speeds clocked as high as 102 km/h.
The brief but powerful gusts downed trees and branches onto power lines and caused thousands of power outages.
