SYRACUSE, N.Y. (WSYR-TV) — A powerful line of thunderstorms swept through Central New York on March 16, 2025, causing significant disruption across the region. By the evening, over 44,000 power customers were left in the dark, with National Grid reporting more than 26,000 outages and NYSEG indicating an additional 18,000 customers affected.
The storms sparked severe weather warnings, issued by the National Weather Service (NWS) at 5:07 p.m., particularly for Broome, Cortland, Onondaga, and Tioga counties. Residents were alerted to pending gusts of up to 60 mph, which rapidly escalated as the weather system advanced northeastward. According to the NWS, “At 5:07 p.m., severe thunderstorms were located along a line extending from 6 miles north of Central Square to near Willet, moving northeast at 60 mph.”
Reports of damage began to surface almost immediately as residents noticed the winds wreaking havoc on homes and trees. The NWS warned, "Expect damage to roofs, siding, and trees," as the storm progressed. This precarious situation prompted local authorities to reinforce public safety messages, advising people to remain vigilant for potential tornadoes. "Remain alert for a possible tornado! Tornadoes can develop quickly from severe thunderstorms,” the agency cautioned.
By 6:30 p.m., surge reports indicated the storm had cleared Syracuse, yet the danger persisted. Strong non-thunderstorm winds gusting past 50 mph were expected to last until 8 p.m., raising the specter of additional power outages. Residents throughout Onondaga County were particularly affected, with more than 13,000 National Grid customers isolated from the grid.
Additional warnings continued to disseminate as the NWS updated its predictions at 5:47 p.m. for Madison and Oneida counties, predicting similar gusts. An updated warning stated, “At 5:47 p.m., severe thunderstorms were located along a line extending from six miles northwest of Boonville to near Waterville, moving northeast at 60 mph.” This uptick drew heightened concern from local communities.
During severe storms, the NWS emphasizes the importance of preparation, such as having emergency plans and access to shelters if tornadoes develop. Residents were reminded to seek interior rooms on the lowest floors of sturdy buildings and avoid windows to reduce hazards.
Across Central New York, specially organized safety tips were circulated to guide individuals on best practices during thunderstorms and high winds. The guidelines included monitoring the cloud formations and listening for thunder, which signifies nearby lightning activity. It was noted, "If thunder is audible, it's a clear indication of nearby lightning. Seek shelter immediately.”
Public service announcements reiterated the common risks associated with extreme weather, including the hazards of downed power lines and flooded areas resulting from excessive rainfall. With the storms contributing to many power outages, local power companies immediately mobilized to assess damages and restore service as quickly as possible.
With heavy rains often leading to increased risks of flooding and treacherous road conditions, additional awareness was needed. Those traveling were advised to be particularly cautious during downpours, which can contribute to slippery roads and diminished visibility. The first half-hour of rain can significantly increase road slickness, making driving hazardous and necessitating cautious behavior behind the wheel.
Efforts to return conditions back to normalcy are underway as local authorities coordinate with emergency management agencies to deal with the aftermath of the storm. Power companies were optimistic about restoring electricity, but at the time of reporting, restoration timelines remained uncertain.
Citizens were encouraged to report any downed lines or dangerous conditions to local officials immediately. The restoration of power will be consistently updated by utilities as crews work around the clock to address the damage. Local stations and news outlets are expected to provide consistent updates on weather changes and safety advisories until the threat subsides.
This storm serves as yet another reminder of the unpredictability of Mother Nature and the significance of preparedness; as Central New York residents continue to monitor conditions and execute caution as they navigate the aftermath of the severe weather.
