Flood Risk in Northeastern US
Ida is direct to continue wreaking devastation days after making landfall, more than a thousand miles to the northeast of where it made landfall on US soil. A significant amount of rain will pour down from areas of the central Appalachians to the mid-Atlantic and New England when the system unleashes a deluge through parts of the Tennessee and Ohio valleys, with the potential for life-threatening and devastating floods.
The system will continue to track northeast across the central and eastern United States, with wind intensity decreasing as it does so. Early Monday, Ida was still a tropical storm over western Mississippi, with sustained gusts of 40 mph, but by the time it hits the Northeast in the middle of the week, it will most likely be a tropical downpour.
The system will continue to track northeast across the central and eastern United States, with wind intensity decreasing as it does so. Early Monday, Ida was still a tropical storm over western Mississippi, with sustained gusts of 40 mph, but by the time it hits the Northeast in the middle of the week, it will most likely be a tropical downpour.
This combination will result in massive rainfall, even compensating for the storm’s rapid and constant forward advance. “Many places along Ida’s route from the middle Appalachians to parts of the mid-Atlantic and southern New England are likely to have rounds of rain over a 12- to 18-hour period, although severe rainfall can linger six to eight hours Meteorologist,” says the National Weather Service. Rainfall rates of 1-2 inches per hour are possible over that six- to eight-hour period, which is enough to cause flash urban and small stream flooding even when soil moisture is dry or ordinary, Meteorologist stated.
From northern West Virginia and southeastern Pennsylvania to northern New Jersey, the Hudson Valley of New York state, and parts of southern and central New England, a band of 4-8 inches of rain is expected. Rainfall of 2 to 4 inches is expected in the southeast. And pockets of heavier rain are possible in both areas, with the possibility of double-digit rainfall in a few cases.
