Northeast may see further flooding
According to the National Weather Service, high levels of moisture in the air, combined with a slow-moving cold front from the west, will bring heavy rain and storms to the Mid-Atlantic and Northeast. Soils in the northeast are already highly saturated with water following severe flooding Pennsylvania, New York and Vermont last week, according to the National Weather Service. This has increased the risk of flooding in those areas.
The Weather Forecast Center (WPC) has issued a moderate flood risk for the New England area. Residents should be aware of impassable roads, overflowing creeks and mudslides. All states from Virginia to Maine are included in the low risk area. High winds can also increase the risk of tornadoes.
