A few days after the passage of a hurricane, heavy precipitation is observed sometimes hundreds of kilometers from the passage of the latter.
The images are extremely spectacular. In recent hours, New York City has been plagued by major flooding and a state of emergency has been declared there by local authorities, who are calling on residents not to leave their homes. Several roads and the subway are blocked in the American economic capital, particularly in the boroughs of Brooklyn and Queens, very affected.
According to BFMTV correspondent across the Atlantic, Pauline Simonet, “it rained eight centimeters in Central Park in three hours, intermittently.” According to her, the situation “was not unexpected” since during the day, “tornado and flood warnings” had been issued and many schools had closed in the American East.
The hardest part may be yet to come
In reality, these floods are closely linked to the evolution of Hurricane Ida, which in recent days has violently affected Louisiana. As confirmed by Christophe Person, weather consultant for BFMTV, “after a hurricane, it becomes a tropical storm or a tropical depression, this is not the case but it is accompanied by a lot of precipitation” which saturated the system. city drainage.
“Post-Tropical Cyclone Ida brings widespread heavy rain and potentially life-threatening flash flooding along and near its path,” the National Hurricane Center confirmed.
Impressively, in Staten Island, it fell 350 millimeters in a few hours, the equivalent of three months of local precipitation and seven months in Paris.
“We had a hurricane which arrived quickly which circulated slowly”, still assures Christophe Person, who believes that “the hardest part is yet to come”.
On its satellite animation, it is also possible to see extremely threatening clouds over New York, where the precipitation “will increase, the worst may be to come with a risk of tornadoes”, estimates -t -he.
These phenomena have already been observed in Pennsylvania, New Jersey and Maryland, where a 19-year-old young man has died and another person is missing.
In the medium or short term, the reminiscences of Hurricane Ida could possibly move to other continents. “They can cross the Atlantic to go to northern Europe and reach England and Iceland,” he concludes.
