An interdisciplinary team of researchers is using a unique model to predict how many U.S. residents will lose power because of Hurricane Matthew.
As of Thursday morning, Oct. 6, the team predicted 9.6 million people will lose electricity.
The model was developed by researchers from The Ohio State University, University of Michigan and Texas A&M University.
“Based on current estimates of its track and strength, Hurricane Matthew is forecast to have one of the larger impacts on the power grid that we have seen,” said TDA affiliate Steven Quiring, professor of atmospheric sciences at Ohio State.

The model looks at a variety of factors at the census tract level to determine who is likely to lose power. Among those factors is land use, such as whether the area is urban and whether it has a lot of trees.
Of course, the model examines average wind speeds and duration, as well as the intensity of the strongest winds. But it also uses data that hadn’t previously been used for these kinds of predictions, such as soil moisture. “Saturated soils affect the stability of both trees and the power infrastructure,” Quiring said.
The team, which includes Seth Guikema at the University of Michigan and Brent McRoberts at Texas A&M, have been using the model to predict hurricane-caused power outages for about a decade.
They correctly estimated that superstorm Sandy would knock out power for about 10 million people in 2012. “When we know the track and the intensity of the storm, our forecasts are pretty accurate,” Quiring said.
The U.S. Department of Energy and the Department of Homeland Security, among other agencies, use the team’s forecasts to help plan responses to hurricanes.
