Children run under a snowstorm in Porto Santo Stefano, 170km (106 miles) north of Rome and 11km (11 miles) from the Giglio Island February 10, 2012. Salvage and rescue operations on the capsized Costa Concordia were faced with a new obstacle on Friday as rare snowfall hit the island of Giglio, and stopping ferry services out of Porto Santo Stefano to the island . Bad weather has already delayed plans to begin removing the 2,300 tonnes of diesel fuel in the Concordia's tanks, an operation expected to take from three weeks to a month once it gets under way. Meteorologists have issued an adverse weather warning for the next 24-36 hours, with snowfall expected in many parts of the country over the week-end, with Italy's interior ministry has advised against all non-essential travel.
