The warm sometimes unstable air mass has created severe thunderstorms across the region.

In many parts of the city, so much rain fell so quickly that storm drains were inundated with water causing localized flooding.

UPDATE – Although less than 10 mm of rain fell at Greater Moncton Airport, some backyard observers suggest more than 100 mm fell in parts of Riverview.

August 2013 didn’t prove to be too warm in Greater Moncton – with the exception of a couple days that reached 30°C – but there were plenty of mild days and evenings which was enough to push the average temperature above normal for the month.
Compared to June and July, August wasn’t plagued with thunderstorms and torrential downpours and only had a couple of really wet days which led to below normal precipitation for the month.
