Haute-Corse placed on alert Yellow Weather Situation to Monitor for the “rain floods” parameter from Thursday May 2, 2024 8 p.m. to Friday May 3, 2024 6 a.m.
Météo France has issued a yellow level meteorological vigilance situation to monitor for the “Rain floods” parameter from Thursday May 2 8 p.m.00 to Friday May 3, 6 a.m.00 at a minimum.
Thursday May 2 morning, a stormy spell affected Corsica with occasional accumulations of around 10 mm. At midday, locally stormy showers still occurred on the island but without particular severity.
An intensification of precipitation is expected in the evening of Thursday and the following night with a blocking of the terrain in a westerly flow.
Friday May 3 at 6 a.m. the 24-hour accumulations reached 100 to 130 mm on the relief of the central range, locally generalized 150 mm.
Temporarily the intensities will be significant with 10 to 15 mm/h. Overflows in the eastern catchment areas are expected with a possible reaction from rivers. The rain-snow limit is quite low between 1500 and 1700 meters, which will attenuate the hydrological reactions with the highest accumulations in the form of snow. On the western foothills we expect 50-70mm. On the eastern foothills, 20-30 mm locally 50 mm. The western coast is on the margin with 10 to 20 mm. The eastern plain remains on the margins.
Note that the wind is also strengthening on the terrain with 90 to 110 km/h. No surge on the eastern façade expected. A few isolated lightning strikes may also occur. The precipitation stops at the end of the night and conditions become calm again.
The Haute-Corse prefecture calls on the population to be extremely vigilant and reiterates the precautionary instructions:
- Do not enter, on foot or by car, on a submerged path,
- Respect the diversions put in place,
- Do not shelter under the trees,
- Respect the instructions given by the security services,
- Avoid walks in the forest and outings in the mountains,
- In flood-prone areas, keep furniture out of water and monitor rising water levels
- Do not walk along the banks of rivers located downstream of dams,
- Listen to the radio station France Bleu RCFM and France3 Corse Via Stella
