The National Institute of Meteorology (INM) placed twenty governorates of the country under yellow alert this Wednesday, January 7, 2026, due to unstable weather conditions combining rain, storms, hail and falling temperatures. The alert system, updated regularly, calls for caution for risk-sensitive activities.
This Wednesday, the National Institute of Meteorology (INM) updated its meteorological vigilance map, placing 20 governorates on yellow vigilance. This alert level indicates weather phenomena that may present potential hazards, such as locally intense precipitation and disruptions that could affect various sensitive activities.
The vigilance map is updated at least twice a day, making it possible to report the evolution of risks in the next 24 hours and to alert the authorities and the public in real time.
Rain, storms, hail… marked instability
The current meteorological episode is part of a widespread unstable situation over a large part of the country. A winter disturbance crosses Tunisia, bringing sustained rains, sometimes accompanied by thunderstorms, particularly in the north and center; storm cells favorable to locally significant precipitation; risks of hail falling in places; a significant drop in temperatures, with colder weather than normal for the season.
This context is the result of a cold air mass that has settled over the country, reinforcing atmospheric instability and making weather conditions more severe than usual.
Marked cold and snow on the heights
Beyond simple rain, this disturbance is accompanied by snowfall on western terrain, particularly in mountainous regions, where temperatures have dropped significantly.
Faced with these alerts, the INM and the civil security services recommend avoiding risk-sensitive activities (work at height, mountain outings); to regularly follow official weather reports; to adapt their movements according to changing conditions.
Yellow vigilance does not mean extreme imminent danger, but increased attention to prevent any incident linked to the announced phenomena.
