Meteolux Issues Yellow Rain Alert for Luxembourg Through Monday Morning

Luxembourg's national weather service Meteolux on 10 May 2026 issued a yellow rainfall alert for the entire country, valid from 18:00 Sunday to 07:00 Monday. Forecasters expect 15 to 30 millimetres of rain over twelve hours, with the bulk arriving from the south in evening hours.

Key facts

• Alert level: yellow (Niveau 2).
• Validity: 10 May 2026, 18:00 — 11 May 2026, 07:00.
• Coverage: the whole of Luxembourg.
• Rainfall: 15 to 30 mm over 12 hours; up to 20 mm from showers, with locally heavier bursts possible.
• Direction of arrival: from the south, peaking in the evening.

What the alert means

RTL Lëtzebuerg reports that the bulk of the rainfall is expected during the evening hours moving up from the south, with showers delivering up to 20 mm and locally heavier bursts possible. Meteolux's yellow level signals weather that warrants caution rather than emergency action — but it puts road-traffic, rail and event organisers on notice.

Practical implications

For the Sunday-evening commute and Monday-morning rush, the practical consequences are wet roads, reduced visibility and a higher risk of standing water on rural arteries that drain poorly. CGDIS had already logged two Sunday-afternoon accidents in Bascharage and Vianden before the alert took effect. Garden-festival, market and outdoor-event organisers planning for Sunday evening across the country are likely to shorten or relocate.

Bottom line

A nationwide Meteolux yellow alert is in force from 18:00 Sunday to 07:00 Monday for 15 to 30 mm of rain over twelve hours. The bulk will arrive from the south during the evening. Caution on roads is the operative ask, especially after a weekend that already saw multiple road accidents.
