State Police encouraged people to stay off the roads as much as possible.
Lemmon said doing so would give the Department of Highways and other emergency personnel "the latitude to get out there and start cleaning, as well as removing other possible hazards from the road."
Flooding was so bad that dispatchers at the 911 center in Spencer had to evacuate.
Emergency calls were routed to nearby Jackson County, then relayed to emergency responders by phone and radio.
No calls were unanswered, officials said, but there was some initial confusion.
"We kind of had to abandon ship, we had to leave everything behind," said Melissa Gilbert, director of Spencer 911 and Emergency Services.
No damage was done to the inside of the center or the equipment there, but Gilbert said an ambulance was lost to the floodwaters.
"This is the worst we've seen," Gilbert said. "We've had water up near the emergency squad but never this high."
Kanawha County's Emergency Response Team activated its Emergency Operations Center at Metro 911 about 1 p.m. Thursday to assist Roane County. Kanawha County Manager Jennifer Sayre said three of Kanawha County's 10 water rescue teams were assisting authorities in Roane County.
Kanawha County Fire Coordinator C.W. Sigman said members of the Pinch and Clendenin fire departments were dispatched to the Wallback area of Roane County to assist with water rescues following the severe weather.
Sigman said he couldn't confirm any specifics of the situation but said it involved the retrieval of children trapped by floodwaters.
Sigman said his office hasn't received any calls regarding storm damage or flooding from Kanawha County residents and resources and responders are being used to assist those affected in surrounding counties.
"Other counties got it a lot worse than we did," he said. "We watched that rascal all night but so far so good."
About 20 members of the West Virginia National Guard were called to State Active Duty to help those in Spencer. Six military vehicles were sent to the area for health and wellness checks and an additional four vehicles were sent loaded down with food and water for those in need, according to a release from the Guard.
Health and wellness teams assist local emergency personnel by identifying needs in storm-affected areas so that needs could be met quickly.
"Our National Guard members are ready and able to assist the local community members in their time of need," Maj. Gen. James Hoyer, state Adjutant General, stated in a release. "We will continue to work with local responders to ensure people are taken care of."
In Calhoun County, dispatchers reported water on W.Va. 16 in Orma. The dispatcher said a lot of small streams were swelling but had not breached their banks.
Firefighters at the West Fork Fire Department moved their fire trucks across the bridge from the firehouse because water was rising around it. The trucks were moved to high ground nearby.
"We've been very blessed," the dispatcher said. "It could have been a lot worse, especially with what they were calling for. Calhoun was very lucky, especially when you look at what's going on down in Roane."
She said she'd heard from others in Gilmer County that they were having issues as well.
A dispatcher in Gilmer County, which also answers calls for Lewis County, said there were more trees and lines down than flooding and that the damage was mostly in the southeastern area of Gilmer and western part of Lewis.
"We haven't had any major incidents, but Sycamore Lick is flooded," she said. "It's notorious for that because it runs right by the river."
Sycamore Lick Road runs between U.S. 19 and Jackson Mills Road.
