Dangerous flood advisory hits Oswego County through Thursday

A flood advisory issued by the National Weather Service is currently in effect for Oswego County, New York, and will remain active until Thursday, April 2, 2026, at 5:45 a.m. The advisory was put into place Wednesday morning at 5:55 a.m. in response to excessive rainfall causing minor flooding along the Salmon River.

Residents in and around low-lying areas near the river are being asked to exercise extreme caution as conditions remain hazardous throughout the day and into the overnight hours.

What is happening along the Salmon River

The National Weather Service has confirmed that minor small stream flooding is underway along the Salmon River, driven by heavier-than-normal rainfall accumulation in the region. While the flooding is categorized as minor, officials are emphatic that the conditions are far from safe — particularly for anyone who may be planning to spend time near or on the water.

Fishermen are being specifically urged to stay away from the river entirely. Strong and fast-moving currents caused by elevated water levels are creating what authorities are calling outright dangerous conditions for anyone in the water or along its banks.

Critical safety warnings for drivers, campers and hikers

Beyond those who fish or recreate on the river, weather officials are extending urgent safety guidance to several other groups who may be affected by the ongoing flooding.

Motorists are being reminded of one of the most important rules during any flood event: if a road appears to be underwater, do not attempt to drive through it. The majority of flood-related fatalities in the United States occur inside vehicles, with drivers who underestimate the depth or power of moving water. Even a relatively shallow flow across a road can be enough to sweep a car off course.

Campers and hikers are also being warned to stay well clear of streams and creeks throughout Oswego County. Waterways that may appear calm or manageable can rise rapidly and without warning during periods of sustained rainfall, turning a routine outdoor experience into a life-threatening situation. Officials are advising that people be aware of exactly where they are in relation to any nearby bodies of water at all times.

What residents should know about this flood advisory

A flood advisory, as distinct from a flood warning or flash flood warning, typically signals that minor flooding is expected or already occurring — but that the situation does not yet pose the widespread or severe threat associated with higher-level alerts. That said, advisory-level events still carry genuine risk, particularly for those who live, work or travel near affected waterways.

Oswego County has seen a stretch of unsettled weather in recent days. Neighboring counties, including Oneida County and parts of the Finger Lakes region, were under flash flood warnings as recently as Tuesday night following a separate round of thunderstorm activity. Wednesday’s advisory for Oswego County reflects the continued threat of excess water across Central New York as the region works through an active weather pattern.

How to stay informed and stay safe

Residents in Oswego County are encouraged to monitor updates from the National Weather Service and local emergency management officials throughout the day. Conditions can change, and additional advisories or upgraded warnings may be issued depending on how rainfall totals evolve over the coming hours.

Anyone who encounters flooded roads, rising water near their home, or rapidly changing river conditions should not wait to seek higher ground or contact local emergency services.
