White Juan was the unofficial name given to the Atlantic Canada blizzard of February 2004. It was a strong nor'easter that affected most of Atlantic Canada between February 17 and 20, 2004--only five months after Hurricane Juan devastated Halifax on September 28, 2003.

[edit] The Life of the Storm

The storm coated much of Atlantic Canada with 50 to 100 centimeters of snow and dropped an official record-breaking 95.5 cm of snow on CFB Shearwater breaking the previous record of 73.2 cm of snow set February 1, 1960. It also broke the record for the most snow in Yarmouth with 82.6 cm of snow breaking the previous record of 67.8 cm set January 16, 1977

Numerous un-official reports sighted snow totals of nearly 150cm in many regions across the province. The storm also produced sustained winds ranging from 60 to 80 km/h through much of New Brunswick, Nova Scotia, Prince Edward Island, Labrador and Newfoundland with maximum 1 minute gusts of 120 km/h reported at numerous stations.

Two weather stations in the Halifax Regional Municipality reported 10 seconds gusts nearing 147 km/h however these reports have never been confirmed by Environment Canada. Weather radar observations as well as synoptic reports showed numerous thundersnows embedded within the blizzard some of which produced snow accumulation rates that exceeded 20 cm per hour.

The wind combined with the intense snow rates produced visibilities of 1 meter or less in most areas for brief periods however these conditions persisted for at least 8 hours in much of Nova Scotia. The wind also whipped up snow drifts which in some cases covered two and three storey buildings and made many roads impassible to both common motor vehicles and snow removal equipment.

For several nights following the storm, a 10pm curfew was implemented on Halifax residents to permit snow removal equipment to clear roads and highways. Due to a lack of space to transfer the cleared snow, it was deposited into the Halifax Harbour.

[edit] Schools affected

The majority of all school districts that were affected by the blizzard closed schools for at least one week, even after it stopped snowing. There was so much snow fallen on the roads that plows had to plow the snow into the school parking lots, which caused the long-term school closure. Due to the number of school days cancelled, school boards were considering the allowing of classes to continue into July instead of the usual ending of school in June. Ultimately, the next school year started earlier and ended later.


[edit] Marine Effects

While conditions on land proved to be serious, the storm produced hurricane force winds out at sea with 10 to 15 meter swells, prompting a special marine warning. A storm surge equivalent to that associated with a category 1 hurricane also affected portions of Southeast New Brunswick and to a much lesser extent Prince Edward Island.
