A look at the storms of the century: Lothar and Martin
Almost a quarter of a century ago, at the end of 1999, France found itself facing two of the most devastating natural disasters in its recent history: storms Lothar and Martin. These events shaped memories not only with their violence but also with the deep wounds they left.
A dramatic series of climate events
- December 26, 1999: Lothar wreaks havoc in the north
- 27 December 1999: Martin moves south
- Damage is estimated at between 8 and 13 billion euros.
- Economic loss of half a percentage point of GDP for France
In the last month of 1999, France witnessed very severe storms and floods. The culmination of this series was Lothair and Martin, which killed 92 people and caused great damage to both infrastructure and the natural environment.
Distorted meteorological context
Since the beginning of December the climate has been extremely unstable and heralds imminent unrest. The year 1999 was characterized by extreme weather conditions, which caused severe flooding in Aude, especially in November.

The origin of these extraordinary storms lies in the acceleration of ocean currents, unusual fluctuations and extraordinary speeds of the jet stream, that is, very fast air flow at high altitudes. These factors have created favorable conditions for extreme weather events.
The destructive qualities of Lothar and Martin
| Storm | History | Affected areas | explosion speed |
| Lothario | December 26, 1999 | Northern France | Up to 272 kilometers per hour |
| Martin | December 27, 1999 | Southern France | Up to 198 kilometers per hour |
Because of their strength and rapid spread throughout the region, these storms are considered Category 1 hurricanes.
Evaluation and consequences of storms.
- Natural disaster that claimed the lives of 92 people
- More than 3 million homes are without electricity
- 138 million m3 is carried by wind in French forests
The deaths of Lothar and Martin raised national awareness of vulnerability to severe weather events and led to the creation of the Météo France surveillance system in 2001.
Storms and climate change
Although existing studies do not show a direct link to climate change in terms of storm frequency, this is an important research topic, especially considering the potential effects of global warming.
Lothar and Martin will remain hallowed in French meteorological history as a reminder of the forces of nature unleashed and the challenges that arise to anticipate and overcome them.
