FONDA — A deluge of rain Monday afternoon caused power outages and closed roadways in Montgomery County and elsewhere around the Capital Region.

Large hail and torrential rainfall were reported in Montgomery, Rensselaer and Columbia counties, National Weather Service meteorologist Gene Auciello said.

“There were a lot of heavy thunderstorms, large hail and heavy rain that caused some local flooding,” Auciello said.

Logtown and VanEpps roads in the town of Glen were shut down for part of Monday after the rainfall, Auciello said.

Firefighters and road crews were dispatched to Switzer Hill Road at the intersection of state Route 5 just east of Fonda after a culvert beneath state Route 5 was inundated, causing a minor mudslide.

Samantha Youngs, 20, was in her apartment just opposite Switzer Hill Road when she noticed a deluge of water pouring across the road.

The water found its own path over the road and down Youngs’ driveway, leaving a pile of mud and silt in its wake.

“The whole road was just covered. The creek was overflowing, part of it. It was a mess,” Youngs said.

Montgomery County Department of Public Works highway equipment operator Zach McCaslin said the damage to the county’s portion of the road appeared minor, and crews cleaned up debris left along the road.

A crew from the state Department of Transportation cleaned up the state’s part of the mess, McCaslin said.

Traffic was slowed at the intersection of Route 5 and Broadway in Fonda as rainfall reached the height of the curbs as it worked its way into the drain system.

At the height of the storm, National Grid estimated some 900 customers were without power in Montgomery County, mostly in the towns of Mohawk and Amsterdam and in Fonda.

“Most of what we saw today has been weather-related. We’ve had a few lightning strikes on equipment,” National Grid spokesman Patrick Stella said.

Auciello at the National Weather Service said there’s a 30 percent chance of rain for today. A slight chance of rain was forecast for Wednesday and Thursday, he said.

“Friday looks like the best day, with zero percent chance of rain,” Auciello said.
