At least 10 killed after massive flash floods hit Mallorca, 5 months’ worth of rain in 2 hours, Spain
More than 230 mm (9 inches) of rain fell on Mallorca, Spain’s Balearic Islands on October 9, 2018, causing one of the worst flash floods the island has seen in 25 years. At least 9 people have been killed and 6 others are still missing. The worst affected was the island’s northeastern part. Local media described the floods as biblical.
Average rainfall for the entire month of October in Mallorca is just 44.3 mm (1.7 inches). The annual rainfall varies across the island, from 350 mm (13.7 inches) in the south to 1 500 mm (59 inches) in the high areas on the Serra de Tramuntana mountain range. However, most of the island receives between 450 mm and 650 mm (17 – 25 inches) of precipitation over the year.
The probability of 233 mm (9.17 inches) of rain falling in Colònia de Sant Pere [close to Sant Lorenç] in Mallorca, which was recorded on October 9, is one in a thousand years, Spain’s AEMET national weather service said in a preliminary report.
