A fast-moving round of storms Tuesday night dumped several inches of rain across the Finger Lakes, Central New York and Southern Tier, triggering flash flooding, road closures and emergency responses that stretched into the overnight hours.
What began as a line of strong storms — some severe-warned and even tornado-warned — quickly turned into a widespread flooding event, as rainfall totals reached 1 to 3 inches in many locations, with isolated areas seeing as much as 4 inches. The result was rapid runoff, overwhelmed drainage systems and rising creeks and rivers across the region.
What happened Tuesday night
Emergency responders across multiple counties reported a surge in calls as floodwaters covered roads, filled basements and created dangerous travel conditions.
Sheriff’s offices in Yates, Cayuga and Ontario counties all issued warnings about flooded roadways, urging drivers to avoid travel or proceed with extreme caution. In Yates County, fire departments were dispatched to pump out basements while crews dealt with debris and water-covered roads.
Conditions were particularly dangerous in parts of Schuyler County, where multiple road closures were reported in the Town of Hector due to flooding and a culvert washout.
In the Southern Tier, travel became increasingly hazardous. Route 21 between Hornell and Wayland was shut down as water overtook the roadway, while additional flooding created problems across Allegany County, where officials declared a State of Emergency Tuesday night due to widespread impacts.
Nearby Steuben County also issued a non-essential travel advisory, warning that excessive rainfall had made multiple state, county and local roads impassable. Flooding was reported across a wide stretch of the county, including the towns of Dansville, Fremont, Cohocton, Avoca, Wheeler, Prattsburgh, Urbana, Pulteney and Wayne.
What conditions look like Wednesday morning
While the heaviest rain has moved out, the impacts are far from over.
Flood watches remain in effect across much of the region through Wednesday evening, and numerous flood warnings are active for rivers, creeks and low-lying areas. Officials say water levels remain high, with many waterways near or above bankfull after days of rainfall.
Localized flooding is still ongoing, especially in poor drainage areas and near creeks and rivers. In some locations, water has overtopped banks or flooded nearby roads and properties.
Emergency crews continue to assess damage, clear debris and respond to calls, while officials warn that road conditions may remain unpredictable due to washouts, weakened pavement and lingering high water.
What to expect for the rest of Wednesday
Forecasters say the region will get a break from the heaviest rain today, but not a complete reprieve.
Lighter showers are expected through the day, particularly across the Southern Tier, while areas farther north may see some improvement. However, flooding concerns will persist even without heavy rainfall, as runoff continues to move through already swollen waterways.
River and creek flooding is expected to continue through at least Thursday in some locations, with several waterways forecast to crest at or above flood stage.
Officials are also warning that additional rainfall later this week — including showers and possible thunderstorms Thursday through the weekend — could prolong or worsen flooding concerns.
For now, emergency management officials across the region continue to stress caution: avoid flooded roads, stay off the roads if travel is not necessary, and remain alert for changing conditions as water levels shift.
