Extreme bora in progress in SLO/CRO

Currently the winds are locally blowing over 160 km/h, even 180km/h reported. Extreme bora in progress along the Dinaric mountain range in Slovenia and Croatia. I'm not wind chasing today but it sure would be fun!

SW-Slovenia. Scale in bottom right in m/s. Forecast by ALADIN (ARSO).

Istra, W-Croatia.



August 13th 2010 - Cold front passing in Medvedje Brdo, W-Slovenia

The front arrived in the morning. Wasn't expecting much, but got surprised! A morning shelf cloud and what a spectacular one!

August 5th 2010 - Possible supercell near Novo Mesto

Got run over at home with a nice cell in the line. I liked the moist east wind on the ground before the storm. Veering was pretty good in combination with the jet from the south. A nice wall cloud. Could not really tell if the thing was rotating because it was too far away. Pretty dynamic. Higher CAPE would definitely help.

August 3rd 2010 - HP supercell in Slovenia

I had to core punch this supercell but I never got a good look at it. It was really rain-wrapped. A high precipitation supercell with bad structure.

July 23rd 2010 - HP supercell near Portogruaro, Italy

Nice LVL2 outlook was ahead of us. Friend and I decided to chase in Italy, FVG region. The only region that made sense to chase. We got off the highway before Portogruaro for Varmo and Cordoiso. The outlook was bad, no initiation, was afraid that it will result in a bust. Nothing interesting was happening but then suddenly ... a storm! Crazy driving to get ahead of it to intercept but we were too late. Got some photos but the storm was too fast. It ran us over very quickly, especially with the bad roads. Wet microburst with winds over 100 km/h, fortunately no hail. This storm dropped a rain-wrapped tornado somewhere along the way so were kinda lucky. Once the wind was strong and with strong rain there is nothing you can do. Especially with people driving 20 km/h. Obviously there were not in a hurry to get out of there. Before the storm caught us we got a look at a nice wall cloud which was rotating nicely. The storm made quite a bit of damage, there was a lot of broken trees on the roads.

June 17th 2010 - High end LVL1 event in Slovenia

Wasn't expecting much from this day but it went really well. My first sight of the supercell was near Trebnje. It took awile to get on the highway ... Missed the first supercell but bagged the next one, crazy driving saved me! :) These storms dropped large hail near Grosuplje and made a lot of damage.

From Trebnje.

Still very unorganized but very active. I was right under all the action. Crazy lift and inflow. A lot of CGs also, was kinda scared to stand outside of the car! Was dropping hail already.

Crazy inflow. Mesocyclone occlusion began here already with rain on the levt. I was moving practially all the time. It was fast.

A few kilometers ahead. Nice wall cloud. RFD really close, wall cloud already a bit in the rain. Not showing the structure very well.

On the road back along Trebnje. RFD on the left, not looking very good.

I still got one more look on the meso once I got ahead of the storm. Really crappy roads here, impossible to track anything here for long period of time.

On the road back at Krško.

June 6th 2009 - Great day in FVG with supercells!

The forecast was good so me and two friends decided to chase in FVG (Friuli-Venezia-Giulia). Starting point was in Sežana then we proceeded to catch the first thing that came into our range. It was already spectacular on the radar when we started. We caught it close to city Udine.

On the road, still in Novo Mesto.

First supercell on a gas station near Udine. Nice inflow banding. Too bad there were stratus clouds all around us so we didn't get to see much other then the wall cloud and circulation.

Awesome view of the wall cloud.

Spectacular rotation. Too bad we were a little late so we head to do most of our shooting from the car.

Once again the awesome structure of the wall cloud. RFD is now obvious.

On a toll booth, in traffic ... RFD was really cutting into the wall cloud as seen here. Obvious lowering, it was trying to produce a tornado here but it couldn't.

This storm then hit the hills east of Udine. I'm certain that it would produce tornado if there weren't any hills on the way! Next supercell please ...

From the car.

Close to Palmanova. This supercell already dropped 2 tornadoes, one of them F3 with 10.5 km lenght and 250 m width ... Too bad we missed this one also.

Back north.

Interesting structure.

On the same gas station as before. Awesome view!

All over the sky. Nicely illuminated.

Panorama...

Successful stormchase, too bad we missed the tornadoes but that's how it is. Maybe with better CAPE ...
