Atmospheric river storm that floods the northeast with wind and rain

A far -reaching storm, which is reinforced by an atmospheric river, soaks the entire east coast and the heaviest rain and the strongest winds on Wednesday, because it becomes much stronger during the day.

The worst mess of the storm of heavy rain and strong winds will occur in the northeast and ensure a treacherous journey and a miserable day. Winds with gusts of 50 to 60 miles per hour in the afternoon and evening could also lead to power outages all over the region, including New York City and Boston.

“Harmful winds could outline trees and power lines. Large -scale power failures are possible. Traveling could be difficult, especially for top -class vehicles, ”warned the National Weather Service office in Boston, such as buses and trucks.

The atmospheric river, which feeds the system, taps the warm tropical ocean off the coast of the southeast to generate moisture levels that are rarely found in the northeast outside of tropical systems, which leads to faster precipitation rates and the risk of fall floods.

Experts assume that this will be the most moisturable system in the northeast since December last year when large -scale floods killed several people and caused considerable damage to the streets in Maine.

This will be the first noteworthy rain event for a large part of the Central Atlantic and the northeast since August. So while the atmosphere is loaded with potential floods, the continuing drought conditions in the region, including the extreme drought conditions in New Jersey, are likely to limit the spread of flood.

“The main worries will be urban floods and poor drainage as well as traffic jams on streets,” said Prognostics of the National Weather Service Office in Mount Holly, New Jersey.

The drought is due to a record -breaking warm and dry autumn, which stretched into winter. Philadelphia has not registered more than 2.5 cm of rain in one day since August 6th. The last time there was 5 cm rain in New York Central Park, was on August 18.

Nevertheless, the storm could throw a lot of rain, and quickly. From Long Island, New York, north to Maine there is a risk of level 2 of 4 for flood rain, whereby a large part of the east coast is expected with more than 1.5 inch rain and isolated areas of 2 to 4 inches are possible.

The rapid melting of snow in areas in the interior of New England could increase the risk of local falls, especially near smaller streams and low areas.

“Fortunately, after a very dry autumn, the rivers in all of the new England can endure a good moisture thrust, so that the likelihood of considerable floods is currently lower than normal,” adds the Weather Prediction Center.

In areas outside the northeast, the rainfall may not be as high, but in parts of the middle Atlantic there could be some severe thunderstorms on Wednesday.

According to the Storm Prediction Center, there is a risk of heavy storms of level 2 of 5. Devastating wind gusts from the east North Carolinas north along the immediate coast to the south of New England is the main danger for every thunder North Carolina.

Behind this storm, another gush of arctic air will arrive and the temperatures will reduce the normal value again.

In large parts of the northern levels and the middle west, wind cold will occur below zero until Wednesday morning. This will trigger the snow effect in the large lakes again in the middle of the week, and until the end of the week there are 1 to 2 feet of snow in front of the lakes Erie and Ontario.
