In addition to flooding, it is expected that the storm system will bring with it a lot of rain and strong winds, writes Washington Post.
The worst flooding will be in the Baltimore and Washington DC area, according to meteorologist Chis Strong, at the national weather forecast loop.
“Right now we are expecting this to be one of the worst tidal floods we have had in the last 10 or 20 years for areas near the Chesapeake Bay,” Strong said. CNN.

Chesapeake Bay is a large harbor bay on the east coast of the United States, spanning several states. According to the National Park Service, more than 100,000 streams and rivers flow here.
The storm system has already caused record amounts of rain in California, and has led to tornadoes in the south, writes the Washington Post.
During Friday, the water can rise by over a meter. Conditions have not been so bad since Hurricane Isabel in 2003, writes CNN. At that time, large areas were flooded.
According to meteorologist Strong, however, it is not expected that the tidal flood will lead to such massive amounts of water as then, but the tidal wave will probably be the worst since then.

Over one meter of water
For several areas, including along the river St. George Creek, forecasts show that the water can rise by more than 1.5 meters, thus crossing the limit of what is characterized as a major flood, according to the canal.
– Normally, these extreme tidal floods occur as a result of hurricanes or tropical storms. This is just a low pressure, but the strong low pressure works against a high pressure over New England.
The combination causes the eastern ocean currents in the Atlantic Ocean to cause water from here to build up towards the coast of the USA and the Chesapeake Bay, the meteorologist explains.
October has been a dry month in the areas that are now expected to be soaked with rain. Monday’s heavy rainfall, combined with the rain that is now waiting, also increases the potential for rivers and streams to cross their banks, warns the national weather forecast loop, according to the Washington Post.
– Large amounts of precipitation will cause streams and rivers to increase slowly, possibly over their banks. There is also a risk of flooding in urban areas, meteorologists write.
In addition to the tidal flood, strong winds are also expected. IN the danger warning sent out by the national weather forecast loop, it appears that trees and electricity pylons are expected to blow down and that many will lose power.
