Large Waterspout Makes Landfall in Venice

A large waterspout made landfall on the islands of Venice on Tuesday, June 12th. The tornado caused considerable damage on the islands but missed the picturesque city centre of Venice altogether. As the waterspout made landfall on Venice’s lagoon, it traveled towards the island of Saint’Erasmo and Certosa where there were numerous reports of trees being shredded and uprooted, roofs being torn off and the city’s well-known gondolas being thrashed around. Two significant structures that were reported as being damaged include a soccer stadium and a naval academy where a tree fell, trapping 15 students inside the building. Winds were estimated to be howling at a rate of about 145km/h inside the twister at the time it made landfall, classifying it as an EF-1 tornado under the Enhanced Fujita Scale. One man was injured and the damages are estimated to be near a couple of millions of dollars.

Waterspouts in the region are usually associated with small spin-ups and pulse storms over a large body of water, which typically dissipate when making landfall. However, this waterspout in particular had not dissipated as it moved over the islands due to its unusual strength and cone-like shape – signifying strong rotation present. According to a satellite picture taken at the time, it appears a shortwave provided the necessary ingredients to spawn the tornado and lengthen the duration of the storms.

Even though tornadoes are not as common in Europe as they are in North America, Italy has seen its fair share of deadly tornadoes this past century. A couple of notable tornadoes are:

-The Montello tornado in 1930 – possibly the strongest tornado ever to touch down in Europe, it brought gusts of over 500km/h and completely levelled brick buildings.
-The Venice tornado outbreak of 1970 – which included a notable tornado that went through Venice causing deaths and destruction throughout the city.

Storms were reported to have cleared out of Venice’s region near the end of this week. The weekend forecast in that area calls for light showers on Saturday and all-out sun on Sunday.

A couple other notable events that have happened in other parts of the world since last weekend include: a hurricane spinning up in the Eastern Pacific heading towards Mexico’s western coast; and significant flooding in Pensacola, Florida where over 540mm (more than a year’s worth of precipitation in Winnipeg, Manitoba) fell in 24 hours!
