Heavy showers overnight from Monday to Tuesday caused the Liane and Aa rivers to be put on red alert for flooding, according to Vigicrues Flash system, which provides flash flood warnings for small-to-medium ungauged basins in approximately 10,000 cities and towns.

Flood peaks were reached at upstream stations in the Liane, Hem, and Aa basins as of Tuesday. Maximum water levels have been or will be quickly reached downstream later in the day, authorities warned.

The authorities also issued a warning regarding the possibility of treacherous driving conditions and potential power outages. According to La Voix du Nord, 69 towns and villages have closed their schools due to the current situation.
