Storm of 1987

The Tempête of 1987 is a very violent storm which struck Thursday October 15th 1987 the Brittany and the Cotentin before reaching the British Isles. Its intensity was such as it because of the damage equivalent to those of a hurricane of force 2 in the scale of Saffir-Simpson what was worth the name of to him Ouragan of 1987 in certain mediums. However, it was of a synoptic depression of the average latitudes and not about a tropical Cyclone.

Weather situation

The weather had announced a small storm in provenace of the Azores. This one touched the Breton coasts that envisaged later (towards 18:00). This depression moved to 50 or 60 km/h and did only very little damage. However, a stronger depression was formed along its cold face in the the Bay of Biscay when the cold Advection coming from north reached very hot water for the season. This Intrusion of cold air was in conjunction with a fort Courant-jet coming from west and a strong ascending vertical movement which gave him a central pressure of 958 hPa (958 mb).

It reached Ushant at midnight with a pressure of 948 hPa (948 mb) at the weather station of Brest, record of the station since its creation in 1945. It moved relatively more quickly than the first: 110 km/h. It crossed Brittany of Penmarch to Saint-Brieuc. In Brittany, the storm touched ground in the Cornouailles with in Quimper of the continual gusts of 180 kms/h before moving towards the Devon and the counties of the Midlands English before turning over to the sea by the East Anglia. The strongest winds were of 100 nodes or 180 km/h on the south-eastern edge of the depression. The night was long to déconvrir the disaster that never Finistere had not known.

Although this kind of system is rare and that the estimate of such a development has a Temps of recurrence 100 years, in January 1990 a similar depression struck the United Kingdom and France (Tempête Vivian for French and Burns day Storm for the British) and two others in 1999 (see Tempêtes of at the end of December 1999 in Europe).

The fact that this storm was badly provided and that warnings were not emitted in time led to a re-examination of the practices of Weather-France and Met Office. The improvement of the networks of stations and weather buoys as well as work on the models of numerical Prévision of time made it possible to correctly envisage the storm of the Jour of Burns .

Damage

The damage was considerable, but the relatively weak human losses, thanks to the night passage.
