Weather Alerts

Severe Rain Warning (Degree 3/4) - Slovenia / South-East

Slovenia / South-East Sep 9, 06:37 AM - Sep 11, 12:59 AM
Severity: Severe Urgency: Future

Rainfall : from 25 to 70 mm/6h. Floods are possible in the areas near torrential watercourses. Rainwater and backhaul water floods are possible. Debris may clog individual objects of water infrastructure and clog the water flow.

If you notice that a torrential watercourse is rising quickly, first make sure that you move above the area that can be reached by water. Do not attempt to cross watercourses. Only exceptionally, if you consider that it can be done in good time, remove food, movable assets, documents, money and other valuables from lower floors and cellars. Follow meteorological and hydrological warnings and information provided by other competent services and bodies.

Event: Severe Rain Warning Certainty: Likely Category: Met

Moderate Rain Warning (Degree 2/4) - Slovenia / South-East

Slovenia / South-East Sep 9, 06:37 AM - Sep 10, 06:59 AM
Severity: Moderate Urgency: Future

Rainfall : from 15 to 25 mm/6h. Torrential watercourses may rise and overflow quickly. Rainwater floods are possible.

The population in the affected areas should follow the trend of water level and hydrological updates.

Event: Moderate Rain Warning Certainty: Likely Category: Met

Velebit channel region Sep 9, 08:11 AM - Sep 10, 11:59 PM
Severity: Moderate Urgency: Future

Locally strong S and SW wind turning to strong NE wind. Maximum wind gusts 35-45 knots (65-85 km/h)

IMPACT: Although rather usual in this region, locally or potentially dangerous wind speeds are expected to produce dangerous wave conditions to small crafts. Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in these conditions. Mariners should pay close attention to the marine forecast and consider wind and sea conditions in planning. It is possible that some ferry lines will not operate so follow traffic information if travelling.

Event: Yellow wind warning Certainty: Likely Category: Met
