Severe weather in Croatia: Several boats run aground in a popular bay on Unije

Severe weather in Croatia: Several boats run aground in a popular bay on Unije

Unije is part of the archipelago surrounding Lošinj in the Kvarner and is a popular destination for boaters and charter crews. During the night of 19 July, Potkujni Bay became a disaster zone. According to eyewitness accounts, a ‘nevera’ storm swept across the bay from the north-west at around 3.45 am, bringing gusts of up to 60 knots. Within a few minutes, buoys were reportedly torn from their moorings. At least one catamaran and another boat ran aground on the rocks. As things stand, the total number of vessels damaged has not yet been officially confirmed.

What makes a Nevera so dangerous

The Nevera is a thermally triggered thunderstorm vortex that occurs off the Croatian Adriatic coast, particularly during the summer months. It strikes suddenly from the west, is virtually impossible to predict locally and can reach hurricane force within a very short time. What makes it particularly treacherous is that standard weather models often fail to predict it reliably. Anyone asleep stands no chance of reacting – especially if buoys or anchors fail at the first gusts.

An earlier report shows that such scenarios can also become a matter of survival for motorised crews in the region, Boat accident between the islands of Pag and Rab, in which four German holidaymakers found themselves in a life-threatening situation following a storm and engine failure.

Shipwreck south of Cape Kamenjak

Quite apart from the events on Unije, a sailing yacht with an Austrian crew found itself in distress south of Cape Kamenjak. According to reports, the boat was shipwrecked. Three people transferred to a life raft and were subsequently rescued. It has not yet been officially confirmed whether the incident is directly linked to the storm system that occurred during the night.

Campsites on Lošinj have been hit hard

On land, the storm caused considerable damage around Lošinj and Nerezine. Campsites were devastated and trees were uprooted. No definitive official figures are yet available regarding the exact number of people injured on land. As things stand, there have been no confirmed fatalities.

What boaters need to know right now

Potkujni Bay is not an isolated case. Popular anchorages in the Croatian archipelago often offer little protection when a ‘nevera’ blows in from the west. If gusts shift to onshore directions and buoys or anchors fail, even a seemingly calm bay can turn into a trap within minutes. For the current summer season, the following applies: the weather conditions in Kvarner Bay should be reassessed daily, even when high-pressure systems are stable. An anchor watch or at least a wind alarm system on board can be crucial in an emergency.
