A round of strong thunderstorms swept through Herkimer and Hamilton Counties Sunday evening, bringing with them gusty winds up to 50 mph, penny-sized hail, and frequent lightning. The National Weather Service issued a severe weather alert at 5:21 p.m., warning residents to brace for hazardous conditions through at least 6 p.m.
According to meteorologists, the storm was first spotted by Doppler radar about 8 miles north of Ohio, New York, or roughly 18 miles south of Old Forge, moving east at around 15 mph. The system had the potential to down tree limbs, scatter unsecured items, and cause minor hail damage to vegetation.
The storm targeted a number of rural communities including Caswell Lake, Mountain Home, Nobleboro, Atwell, Wilmurt, Wheelertown, Wilmurt Corners, Morehouseville, Hoffmeister, North Wilmurt, and Herkimer Landing.
The bigger concern, however, was the frequent cloud-to-ground lightning associated with the storm. Meteorologists reminded residents that lightning can strike up to 10 miles from the storm’s core, creating a danger zone well beyond the rainfall or thunderhead.
“If you’re close enough to hear thunder, you’re close enough to be struck by lightning,” forecasters warned.
Lightning safety top of mind as storm season peaks
This latest round of thunderstorms comes as lightning activity reaches its seasonal peak across the United States. Every year, lightning strikes the country approximately 25 million times, and on average, around 20 people die as a result.
The greatest danger occurs as a storm approaches, but lightning risk can linger even after the last flash is seen or the final rumble of thunder fades. Weather experts stress the importance of seeking shelter indoors or inside a hard-topped vehicle at the first sign of an approaching storm.
Heavy rain makes roads slick and visibility poor
Alongside the electrical threat, heavy downpours have made travel across the region hazardous, particularly on rural highways and back roads. The first 30 minutes of rainfall are especially treacherous, as built-up oil and grime on the road surface combine with water to create slick conditions.
Drivers are being urged to slow down, keep their headlights on, and leave extra space between vehicles. Hydroplaning remains a serious risk, particularly at higher speeds or in pooled water. Those driving near large trucks or buses should be cautious, as their spray can severely limit visibility.
If the rain becomes too intense to drive safely, officials recommend pulling over to a safe area—ideally beyond a guardrail—and turning on emergency flashers to alert other motorists.
Conditions likely to remain unstable through Sunday night
Forecasters say the storm system could continue to impact parts of Central New York into the late evening, with additional lightning, rain, and gusty winds possible overnight. While the worst of the system may pass quickly, scattered showers and storm cells could linger.
Residents in Herkimer, Hamilton, and nearby counties are encouraged to stay weather-aware, especially if planning to be outdoors. Even after the storm moves on, residual risks like downed branches, localized flooding, and slick roadways may persist well into the night.
