Venice suffers the worst flooding in 53 years.

The city of Venice in northern Italy suffered its second worst flooding since records began on Tuesday 12 November 2019, with waters reaching 1.87 m above average levels at high tide, a level surpassed only by the flooding of 1966, when the waters reached 1.92 m above average. The flooding is thought tohave caused hundreds of millions of euros of damage to the historic city, as well as causing two fatalities. Both of the known deaths associated with the flood occured on the island of Pellestrina, which forms part of the barrier between the Venetial Lagoon and the Adriatic Sea; one of the fatalities was reportedly due to a man beong electricuted while trying to start a pump in his flooded house, the cause of the other has yet to be disclosed.

The flooding was caused by a combination of a spring tide, in which the Sun and Moon are aligned either on the same side of the Earth or directly oposite (as was the case this week), leading to high tidal waters, and a storm surge caused by a low pressure system over the Mediterranean. The low pressure above areas of sea causes water to rise there by ~1 cm for every millibar drop in pressure, leading to a storm surge that can overwhelm low-lying coastal areas.

  1. I am so happy that i got cured from herpes virus 1&2 after i have suffered from this virus for over 3 years. I have been using drugs to suppress it,i got introduced to doc tor razor by a friend of mine who knew i was herpes positive, she believes in herbs, and i have full doubt on her idea to try out herbal medicine. I contacted the doctor and told him what i was passing through, so he promised he was going to get me cured completely. I am so glad that after applying doctor razor herbal remedy for 18 days there is no trace of the virus in my body as confirmed by the results given to me by the medical hospital,where i conducted my test. I am so grateful Doctor Razor. For those who are in same situation just like i was, you can reach out to doctor razor on email : drrazorherbalhome@gmail.com , WhatsApp or Call him on +2349065420442.
