This past Wednesday evening a severe weather outbreak comprised of severe winds and strong tornadoes occurred in the southern United States, causing damage to rural areas of Northern Mississippi. This was brought on by the same system we experienced over the past couple of days. The polar jet stream along with a strong low level jet overhead and plenty of moisture from the Gulf of Mexico combined to create conditions ripe for tornadoes in Dixie Alley.

The strongest, a half-mile tornado, rated EF-3 by the National Weather Service, touched down near Jackson Mississippi and caused quite a bit of damage, tearing up large trees and wrecking mobile houses. As the tornado trekked for 26 kilometers, nine people taking cover inside mobile houses were injured but thankfully no fatalities occurred during this event. As the night wore on, more tornadoes touched down in Mississippi and Arkansas, doing damage to rural homes and cutting off power to residents.

A few colder days will follow the trough this weekend and a return flow will set up, bringing warm and humid weather back to the region. Weather models are showing another large trough will likely develop late next week, bringing the potential for more dynamic weather. Of course, it is not uncommon to have severe weather in the southern US during the spring and fall, when the polar jet is in the vicinity.
Elsewhere in the world the weather has remained relatively calm, except for this unusual tornado in France.

Tornadoes in France are not rare but are not a common sight in October.
On Saturday July 14th, an unusually strong tornado struck the northern half of Poland leaving a large path of destruction in its wake, in the region of Pomerania. The twister, at times measuring one kilometer in width, tore up trees, disintegrated houses within seconds, and downed power lines for several kilometers. The village of Wycinki and surrounding forest, Bory Tucholskie National Park, were hit the hardest: upwards of 500 hectares of forest were completely flattened by the tornado; over 100 homes were destroyed; and trains had to reroute because of fallen debris on the tracks.

The tornado was estimated to be of EF-2 strength with winds churning at around 200km/h. One fatality in the village of Wycinki was reported when a man tried to take cover in his cottage and was struck by the walls collapsing on him. There were also an additional 10 injuries reported due to the tornado.

Severe weather in Poland appears to be occurring more frequently these past years. This year alone, Poland has seen its fair share of severe weather spanning from large hail events to flash flooding. Tornadoes are not a common occurrence in Poland but they have happened before. The following lists a few significant outbreaks recorded in the past:
The Lublin, Poland tornado of 1931 which killed six people and is thought to have been an EF-5 tornado (however that ranking has not been proven).
The May 1958 2-day tornado outbreak in Poland which caused three deaths and over 100 injuries.
The August 2008 outbreak where multiple tornadoes including 5 EF-3 and 1 EF-4 were spawned killing three people in south-central Poland.

5 years ago today, Canada’s first official F5 tornado touched down in the small community of Elie, Manitoba. It destroyed several homes, completely sweeping them away from their foundations. Trees were debarked, vehicles were destroyed, and the town’s flour mill was damaged. While it was originally rated an F4 tornado, after extensive investigation by Environment Canada it was upgraded to the country’s first F5 tornado, with estimated wind speeds exceeding 420km/h.
The following is a personal account from a friend of mine, storm chaser Justin H., who was out that day and witnessed the tornado first hand. I thought it fitting that on the 5th anniversary of the event we would have an account of the event from somebody whose enthusiasm for severe weather goes nearly unmatched. Justin, thank you for writing this and contributing to the site; I hope that you all enjoy reading about his experience.
A Personal Account of the Elie, MB Tornado
Written by Justin Hobson
I remember this day like it happened just yesterday. This tornado event will be forever etched in my memory as long as I live. The sights, the sounds, the smells. I still remember shifting my head up to take in the full extent of what was later known as Canada’s strongest documented tornado.
Conditions were favorable for severe thunderstorms on June 22nd, 2007 over much of Southern Manitoba as winds turned and increased with height in combination with high heat and humidity. These conditions favored rotating thunderstorms (Supercells). Storms were supposed to form along a cold front that was oriented from NE to SW across WesMan. A warm front was draped to the east through the Interlake with a surface trough dissecting the warm sector in half oriented north-to-south through Portage La Prairie. The warm sector was capped (inhibiting convection) for much of the day, but a tornado threat existed from the get-go if the cap were to be removed. The cold front was the definite trigger for storms but what was unusual about this day was that the combination of gravity waves originating from the MB Escarpment, horizontal convective rolls within the boundary layer, and moisture convergence allowed the cap to erode before the cold front arrived paving the way for explosive supercell development around 5:30 pm local time (2230 UTC) just to the NW of Elie.
I left work that afternoon with tornado chances fading because of the capping issues that were present all afternoon. I had planned to chase this setup for a week prior (models did a decent job in advance) so I was feeling upset as I was looking forward to chasing in my backyard around Winnipeg. As I left downtown and headed down Highway 3 towards home, I could see what looked to be like a volcanic eruption to the NW of my location. There was explosive cell development occurring southeast of Lake Manitoba. I continued home and was starting to get excited. The first thing I did upon arriving at my house was check the radar on weather office. Woodlands radar was already detecting this cell with some returns starting to show up NW of Elie. I said to myself, well I’ll pack up my gear in the mean time and if the next scan gets better…I’ll go for it. I grabbed my Dad’s camera, a baseball cap and went back to my computer. I clicked the reload page button a few times before the new image displayed its true beauty. A supercell was being born. It was in the right spot within the area of low pressure, and it was in the tornado zone that was analyzed earlier that afternoon.
I headed out, this time on Highway 2 towards Starbuck, Manitoba. Once I arrived in Starbuck I started to get rained on fairly heavily by the storm as I shifted directions and headed north out of town. I thought to myself, oh great the cell has already collapsed. I continued pressing north. Visibility was reduced as the rain got heavier and heavier. Some small hail (pea-sized) began hitting my car as I arrived at a crossroad that would take me west towards Elie (1 mile south). I headed towards Elie as the rain/hail began to ease. What I saw next was remarkable. A wall cloud! I couldn’t believe it…this was the first wall cloud I’ve seen that showed tor’ific potential. I parked on a gravel road just to the south of Elie, I placed my camcorder on the roof of my vehicle, hit record and watched.
Within minutes funnels began to form. I was so excited! A funnel would form, go back up, then a new one would form and reach a little further towards the ground. This happened several times before a long rope funnel reached toward the ground. My first tornado! I snapped some pictures and called Environment Canada to report what I was witnessing. Within minutes, the tornado grew larger, then smaller again, and then it really got its act together. It grew into a large cone tornado that almost looked blue from my vantage point. This was truly amazing. I couldn’t believe what I was witnessing.
“Her last words to me were “Oh…well…don’t die!”
My heart was racing…I had knots in my stomach (like what you get just before they pull the trigger at a 100m race). I was on the phone with Environment Canada reporting the change in shape and size to a forecaster named Curtis. Once I called that report in, I was on the phone with some friends as well as my sister Bryanne. She told me she heard that there was a tornado near Winnipeg. I told her I was right beside it near Elie…and that I thought that the tornado would hit the town…her last words to me were “oh…well…don’t die!” I put the phone down and took in the sight. I couldn’t believe what I was seeing…after 10 years of being passionate about severe thunderstorms…and after 4 years of chasing…I’ve finally done it.

I vividly remember how calm it was and was very observant to what was occurring all around me. I remember hearing Killdeer birds chirping away, as well as frogs in the nearby ditches. I also remember mosquitoes flying around and buzzing in my ear, and I can also remember hearing the constant low rumble of thunder to the east of my location. All of this was occurring while the tornado peacefully and slowly twisted its way across open fields towards the southeast. A passerby named Jason stopped by and was just as excited as I was. We exchanged a few words and I even snapped a picture of him with the tornado in the background. I obtained his email address to forward him the picture later on, and he was off to check on his house…he thought it may have been hit. By the time he left, the tornado grew larger and became darker in appearance. I could hear the tornado now. The only thing that resembles the sound in the real world is that of a waterfall. It was like someone was turning up the volume of this ‘waterfall’ as the tornado sluggishly crept closer.
“The tornado continued to hurl debris which could now be seen very high up into the sky wrapping around the tornado.”
At this time the tornado wasn’t growing larger…it appeared stationary for a brief time before it suddenly began moving to the right (East). Shortly after shifting its track I could here different sounds as large pieces of debris were being hurled around the circulation. It was hitting the town. I began to feel uneasy. Lightning started to grow more intense so I fled to my car with my camera and continued to record the tornado. Power flashes occurred for a brief moment as the tornado severed power poles while impacting the neighborhood on the west side of town. A friend named Chris called me and said that he heard there was a tornado near Elie and that the clouds over his head in SW Winnipeg were crazy (Mammatus likely). I told him I was near Elie and the tornado was hitting the town and that I would call him back later. He said to stay safe and hung up.

The tornado continued to hurl debris which could now be seen very high up into the sky wrapping around the tornado. The tornado was moving to the left now (West) where it grew thinner, and thinner, then suddenly disappeared. It was over? I wanted to get out of the area just in case the tornado redeveloped over my head. Shingles and insulation began to hit the vehicle and land all around the highway as I pressed north towards town. As I entered the town I could see a police car, an ambulance and what looked to be two dated fire trucks heading down a residential street towards the area that was impacted. There were several local residents rushing to the scene so I didn’t enter the town.
Upon making that decision I looked to my West and saw another tornado. I quickly did a U-turn and began to record the tornado as I drove back to the south towards Highway 2. The tornado was large and lasted for quite some time before becoming wrapped with rain and dissipating. This tornado was later rated an F3 after devastating a farmstead near the town of Oakville.
Well that is my story of the Elie, Manitoba, F5 tornado that occurred on June 22nd, 2007. This is the first time writing a detailed personal account of the event and it gave me welcomed goose bumps in doing so. I hope you enjoyed it!
Justin Hobson has recently completed a masters thesis on the F5 tornado in Elie. You can view it here.
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!
