Slovenia / South-East Jul 22, 08:45 AM - Jul 23, 09:59 PM
Severity: Moderate Urgency: Future

Thunderstorms are possible, accompanied by local intense precipitation and gusty winds. Intense local showers with wind blasts and lightning strikes are possible. Torrential watercourses may rise quickly. Rainwater floods are possible.

Beware of approaching storm clouds. Do not linger in exposed locations, e.g. under trees or power lines. Wait in a safe place, as storms usually do not last long.

Event: Moderate Thunderstorms Warning Certainty: Likely Category: Met

South Dalmatia region Jul 22, 05:48 PM - Jul 24, 11:59 PM
Severity: Moderate Urgency: Future

Locally 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.
