As weather conditions improved, coastal areas began cleaning up the damage. Ferries to the islands began operating again after vessels were harbored all day Tuesday due to an extremely high Jugo wind. The first ferry out of Split sailed for Brač at 9 a.m. Catamaran lines were still suspended until evening due to rough seas.

Firefighters responded to dozens of emergency calls throughout Split-Dalmatia County on Wednesday as people reported flooded basements, fallen debris from buildings, and downed trees and power lines. Several intersections were severely flooded, leaving some vehicles stranded. Those cars had to be pulled out.

Water authorities said there had been some contamination at the source of the Jadro River, but Split has enough clean water stored that tap water remains safe to drink.

The situation was similar in Dubrovnik this morning. Firefighters were working to remove fallen trees and branches blocking roads and sidewalks.

The powerful storm made for extremely rough seas. A record-breaking wave was recorded in the Dubrovnik area. The Croatian Hydrographic Institute reported a massive 11 meter-tall wave near the island of Sveti Andrija.

Several ships were damaged in Zadar port overnight, while another boat sank in Sali. Most of the damage was limited to fallen trees.

"We had high winds and rain, but they were not severe enough to cause serious damage. Most important, there were no fatalities or even injuries," said Miroslav Andrić, the head of the civil protection service in Zadar.

Firefighters also had to clear large amounts of gravel that the sea had washed onto roads directly adjacent to the shore throughout the Zadar area. There were also a few rockslides, but nothing that caused any more serious damage.

Southeasterly wind gusts in Istria last night were clocked at 150 km per hour. The sea spilled onto the waterfronts in Pula and Rovinj. The main square in Umag was under 50 cm of water this morning.

Firefighters in Istria also had their hands full with removing trees, pumping out flooded basements, and rescuing vehicles stranded under water. Several sections of the Istrian Y, the major highway on the peninsula were closed for several hours due to flooding. All roads in the area are now open.

The weather is expected to improve tomorrow, but it is only a brief reprieve before more rain in the days ahead.
