Warnings

Maltese Islands Weather issues weather warnings, which warn of imminent severe weather. Warnings are normally issued 12 to 24 hours before the onset of severe weather. Severe weather includes:

• Strong winds: Force 7 or stronger
• Heavy swell: Swells of 2.5 meters or higher
• Heavy rainfall: A day with a national average of at least 25 mm of rain
• Severe thunderstorms: When there is a risk of at least one of the following: wind gusts of at least Force 8, hailstones with a diameter of at least 2 centimeters or waterspouts and/or tornadoes
• Heatwaves: A run of at least 3 consecutive days with a maximum temperature 5°C above the average maximum in June, July, August or September

Our warnings are designed to inform the general public of any hazardous weather that may be in store and what impacts that particular weather may have. Maltese Islands Weather operates on a 24/7 basis and so warnings may be issued at any time, day or night.
