In the last few days a large portion of Italy was hit by a very intense rain and wind, so I want to quickly post some data and pictures about it. So that it would take a ton of time to collect all the information by myself I use this article as a reference. |

Still getting a bit of rain here in Saskatoon as the final autumn-like temperatures make their way out. It was raining somewhat yesterday, a bit drizzly today and there's some potential rain in the forecast for Sunday. After that the highs are dropping below freezing and any further precipitation we get will likely be snow until sometime in March or April. See you next year, rain!

urania93Judging by your posts, it looks like most of Italy has been very wet in the past 6-8 months, especially recently (obviously).

urania93 Judging by your posts, it looks like most of Italy has been very wet in the past 6-8 months, especially recently (obviously). For the most of Italy October and November are the most likely period of the year for this kind of intense rain and strong wind events. More than the intensity of the event itself the uncommon factor this time was the extension, because usually severe weather conditions hit just a couple of regions, while this time there were widespread disasters on the most of the country. As for the rest of the year instead, I can say that for my region any month (apart from September) since the last January has been more rainy than the average, both considering the accumulated rain amounts and the number of rainy days. Ironically the second half of 2017 was extremely dry instead, and exactly one year ago we were struggling with extended wildfires all over the region. As for the rest of the country instead I'm not completely sure, and probably there are regional differences as well. Anyway, my impression is that overall 2018 has been more rainy than usual for the most of the country. In particular I read more than once that the last summer was significantly more rainy than usual in the most of southern Italy (so it basically rained quite a lot even in places which usually have dry summers like Calabria or Sicily). |

The way things are going, Norrköping could possibly have its driest year in recent memory, especially considering how dry the early part of November looks set to be:  Looking at this it's also interesting to note that September has been so dry in the last 17 years. It really sticks out when considering how rainy August often is and the perception of October/November with the drizzle. |

It is raining a lot again, several rivers in the region are close to flooding right now As a quick update, this is the precipitation map of my region for today (it would take too much time to look for a national one, but the situation is similar over several other regions)  It is basically raining a lot over all the valleys, this time my valley seems to be the lest interested by the event, while there is little rain over the plains and hills on the east. Anyway, this means that all the little mountain rivers are reaching their limit, and when they meet in the plain in larger rivers like the Po the water level is sufficient to cause small floodings.  ^ for example in Turin the Po river invaded the "Murazzi", which are an area just above the normal river level. There is also a live broadcasting on youtube for the situation of the Po river in Turin. |

Are the closest rivers to your home still fine urania93? I really hope so, but I would guess it'd have to cease raining quite quickly for the situation to remain stable? Either way, does Turin have a good urban planning to make it less prone to flooding onto the streets? In Nyköping, the ground and the walking paths just beside the rivers are raised by several metres and the river is also controlled by artificial waterfalls so it would take a gigantic catastrophe the likes of which hasn't happened in recorded history to flood the town. |

In the last couple of hours it rained quite a lot in the part of my valley just east of my place, the weather station for that area measured 96.6 mm of rain for today and it looks like there is some minor issue (flooded streets) occurred in some of those towns. Anyway, at the moment the Po river in Turin is about 4 m higher than its usual level, and it can take about another meter before flooding in the middle of the urban area. It should stop to rain in these hours, so the situation is supposed to don't get worse than this. Something like this happens something like once every couple of years in here, while very severe situations (like NE Italy last week) are rarer (the last ones being in 1994, 2000, 2008 and 2016). |

Sounds like a very volatile situation but it's good it's supposed to stop! 96.6 mm in one day is beyond comprehension to me, I don't think I've ever experienced above 25-30... Of course I've been living in a rain shadow of sorts all of my life though. Normally when 20 mm is forecast it ends with half of it. Inland areas on the other hand can get a bit more like that, for example the Uppsala train station flooded last summer. Has public transport gone without issues so far this week though urania93? |

The highest value at the moment is about 155 m in the north part of the region. Last week was a little bit worse actually, so a lot of today's problem are due mostly to the sum of the two events. As for the public transport, up to now there are not issues related to the weather where I have to pass, but there are a couple of other valleys were the situation is much more complicated. |

Looks like I was wrong, we had a bit of rain in the afternoon today while it was -4C! That will almost certainly be the last one until the spring now. |

The first thunderstorm day of 2019 is a good one. Had a very close strike a little while ago, thunder was instant. A second line is coming in behind it.  |

Six days with thunder so far here this year. It seems like lately a lot of our t-storm activity has been nocturnal. Haven't really had anything that impressive in a while; I guess the most intense storm this winter occurred in the early morning hours of January 19.
The past couple of severe weather possibilities failed to materialize here. May get something the middle of next week.

Pretty impressive thunderstorm for the temperature of only 45F today (28th). Lots of lightning. Reports of some small hail in Maryville. Hail fell in Platte City yesterday (27th) also.

Number of days with thunder reported at Blue Grass Airport since 2000:  I made this using the annual summaries published by NCDC. The average of 29.2 for this period is well below the "normal" of 39.8. I can probably do a few more US locations if anyone wants it. |
