Snow is not unusual in Alberta in August but nevertheless no one wants to see it in late summer.

Calgary received a trace of snow while several centimetres fell in the foothills and in the Rocky Mountains.

The snow was part of a wild weather system which also brought thunderstorms, heavy rain, flooding, strong winds, a confirmed tornado and even a waterspout.

A tropical depression-like low pressure system crawled over the American Gulf Coast states during the last week delivering a deluge to Louisiana.

Already prone to flooding due to its low elevation, some parts of the state were hammered with more than 700 mm of rain in only 48 hours.

More than 40,000 homes have been flooded with thousands forced to evacuate.

The American Red Cross has declared the Louisiana floods the worst U.S. natural disaster since Hurricane Sandy in 2012.

Greater Moncton recorded its highest rainfall event of the summer yesterday when more than 35 mm fell during what has been a very dry season.

Much of southern New Brunswick received between 20 and 60 mm of rain while unofficial reports in central Nova Scotia indicated as much as 100 mm fell.

The moisture lifted a burn ban across the region and helped temper forest fires in southwestern Nova Scotia.

The precipitation has also been welcomed by many farmers who have been struggling this summer.
