Juan hurricane

This article is in connection with the hurricane having taken place in 2003; there also was a Ouragan Juan in 1985.

The Ouragan Juan was a hurricane of category 2, according to the scale of Saffir-Simpson, which struck the Canadian provinces of the Nova Scotia, of the New Brunswick and the Island-of-Prince-Edouard in 2003. It was formed in the south of the Bermuda the September 24th 2003 starting from a tropical Onde on the Atlantic Ocean. The wave intensified gradually on warm water of the Gulf Stream reaching category 2 the September 27th by continuing a frankly northern trajectory. Its brought back maximum wind was of 165 km/h whereas it approached the coasts of Nova Scotia quickly. While passing above colder water, it lost a little intensity but was always of category 2 when it struck Halifax, early the September 29th, and remained it while crossing the province. Juan started to weaken while arriving on the Island-of-Prince-Edouard then became a Cyclone extratropical close to the island of Anticosti to the Quebec.

This hurricane made damage for approximately 200 million; $US and caused the death of 8 people, mainly in the area of Halifax. It was the worst hurricane than coast-is Canadian for it knew since 1893 . The hurricane of 2003 was the last to bear the name Juan, this last having been withdrawn of the list of the names like wants it the habit at the time of an important cyclone.

Weather evolution

An important wave tropical in a depressionary zone left the African coast the September 14th 2003 in direction of the west but remained desoragnized because of adverse conditions in altitude September 20th, to approximately 1100 km of the Lesser Antilles, the convection around the system developed in an important way when it met the circulation of a depression of altitude but the conditions were still unfavourable with an organization of this convection. The whole moved towards the North-West under the depression of altitude and developed a cyclonic circulation in the mean levels of the Troposphère. This system entered then in interaction with a frontal zone .

A little later this day, a cyclonic circulation of surface developed in the system but the presence of the frontal zone did not make it possible to classify it like Tropical depression. The major convection intensified close to the center the September 24th and quickly organized in lines of stormy grains in spirals with discernible flow leaving. According to these new characteristics, it is estimated that the wave had become the Tropical depression number fifteen a little later in the course of the day. The latter was to 555 km in the south-east of Bermuda. However, the National Hurricane Center American did not give an opinion before a 27 hours deadline after its formation.

Initially, this system had tropical characteristics and subtropical, maintaining a bond with the frontal zone. But the organization of the convection and the formation of a hot center could only lead to its classification like tropical Cyclone. The Météorologue S predicted that the depression would intensify only slowly and would not generate winds not exceeding 105 km/h . However, the depression was organized gradually and become the Tropical storm Juan the September 25th.

The September 26th, a eye appeared and the convection became very intense near this one . The cloudy model continued to be organized and Juan became a hurricane this day to 270 km in the south-east of Bermuda.

Juan remained with its maximum intensity during 24 hours along a trajectory initially towards the North-West, then towards north, while accelerating. It made entered close to Halifax the September 29th, with winds of 160 km/h. It however quickly lost force by Friction while passing on Maritime Canadian, becoming tropical storm when it reached the Island-of-Prince-Edouard. It was absorbed then by strong a depression extratropicale passing in the Golfe of the St. Lawrence thereafter. September 27th, as the hurricane Juan approached, the first warnings were launched, mentioning the possibility of significant damage by the Vent, by of which electric breakdowns, and floods by the rains and the Onde of storm accompanying the system. The Média S buildings started to make there echo and the public authorities were advised to take the necessary measures for a potential disaster.

The morning of the September 28th, the last reports/ratios indicated that Juan would touch Nova Scotia like a tropical storm or a marginal hurricane of category 1 . The weather reports hitherto indicated that the storm would weaken before touching ground. With 18:00 HAA (2100 TUC), an update of the warnings was emitted because Juan threatened, after revision, to strike in high hurricane force 1 or weak category 2. The majority of the trade in the threatened zone were closed in this Sunday what implies that the preparations for the arrival of Juan were difficult to organize quickly. The inhabitants of the Maritime ones who had seen others of them did not worry in addition to measurement.

The owners of boats made safe their boats and the ministrère defense ordered the redeployment of the ships and submarines in the Bassin of Bedford which is protected better than the port itself. The Canadian coastal Garde put eleven ships of Recherche and rescue in alarm.

Impacts

Nova Scotia

The maximum constant winds at the time of the entry of Juan on Nova Scotia reached the 160 km/h with gusts of 185 km/h and several million of them were damaged or cut down Juan deprived of electricity more 700 000 people in Nova Scotia. Repairs took up to two weeks in the rural regions the most moved back of the east coast of the province and the valley of the Rivière Musquodoboit. The four others dead are related to indirect causes including three due to fires caused by candles at the time of the electric breakdown, the last being rescuer after the storm. The buoys of detection at the entry of the port broke their mooring ropes after having announced waves of more than 20 meters. These waves contributed to the accumulation of water in the port and struck full whip the most exposed places, close to the entry of the port. The erosion of very populated banks of the port was significant, particularly in the Basin of Bedford where the waves of the wave of storm most extremely struck the residences and the ways of the railroad. The wave of storm was most important in annals inside the port of Halifax reaching 1,5 to 2 m but the worst was avoided because the wave of storm arrived two hours before the high tide. If the two phenomena had coincided, the level of water would have been higher of 45 cm, flooding a much more important surface.

With the downtown area of Halifax, rocks as large as dustbins were projected from the port in the adjacent streets. The General hospital Victoria , major, sudden hospital of extensive damage and had to be evacuated during the storm. Several dwellings also had to be evacuated. Many billboards and of road signs were carried by the wind. Cars and trucks were crushed by trees and other remains

Other provinces

Juan left Nova Scotia while crossing the Détroit of Northumberland with an intensity of category 1. It decreased however quickly by intensity while moving on cool water of the Gulf of the St. Lawrence. Gusts to 139 km/h were brought back to Charlottetown (Island-of-prince-Edouard).

The rather localized trajectory of the strong winds of the hurricane made that New Brunswick and the west of the Island-of-Prince-Edouard left there almost unscathed. It disturbed the vote for the legislature of the island of September 29th but in a marginal way since 80% of the voters went there nevertheless .

sudden Newfoundland of the abundant rains which did not have too much impact on the area. Two dead occurred with broad of the Île of Anticosti (Quebec), in the Gulf of the St. Lawrence, where two professional fishermen coming from New Brunswick drowned. Two weeks were necessary to turn on the power in the area A program of afforestation and revitalization was undertook in 2005 and received a million dollars of the Canadian government.

The government of Nova Scotia resolved 10 million Can (of 2003) to come to assistance of the disaster victims and of the private gifts also flowed. The island-of-Prince-Edouard freed as for it 200 000 Can and the federal government announced its personal program of assistance.

The mayor of Toronto of the time, Mel Lastman, contributed to height 50 000 Can of the funds of its city to replace the trees on the Island-of-Prince-Edouard.

Emergency measures

The residents, the governments and the services public of Maritime were strongly marked by the events. Moreover, three major storms had an impact this year in Canada: remainders of the Hurricane Isabel, the Fabian hurricane and the Kate hurricane, as well on ground as at sea.

One thus carried out a recasting of measurements of preparations and emergency in the possibility of another weather catastrophe. That is particularly important with the climatological data which show the probable increase in the hurricanes and the major extratropicaux cyclone because of the total Réchauffement of planet. The measurements taken since 2003 were misent with the test when the hurricane Ophelia was announced close to Nova Scotia at at the beginning of September 2005.

Juan contributed to various changes with the Canadian Center of forecast of hurricane, of the Weather service of Canada. This last was located in a vulnerable building in the district Dartmouth of Halifax and was moved in a less exposed building being able to resist the effects of a hurricane. The bulletins of warnings of the CCPO were modified to resemble those of the National Hurricane Center American. Traditionally, as the hurricanes seldom touch the grounds in Canada, one mentioned there the zones in warning of strong winds, abundant rains and waves of storm, as for a nontropical storm. Even if the warnings launched for the Juan hurricane appeared exact and were given in time, the Post-mortem showed that one draws more the attention of the population if one replaces them by days before and warnings containing the hurricane term in such cases. These changes were operational for the season of the hurricanes of 2004.

Withdrawal

Because of its devastators effects in Canada, Environnement Canada required that the name Juan be withdrawn from the list for any future storm in Altantique. The organization quoted the material losses and deaths, the impact on the economy and the destruction on the territory of two provinces of million trees. It is the first time that the Weather service of Canada made such a request. Indeed, in general hurricanes, or their remainders, affecting the country pass initially along the American coast and the request comes from Éats-Plain. The World Meteorological Organization answered the request favorably and withdrew Juan list. It replaced it by Joaquin for the season 2009 whose list was already published. The names Jaime and Jorge had also been suggested.
