Original story, 5 p.m.:

Flood warnings will be in effect until Thursday for parts of the region.

The National Weather Service has issued a flood warning for Oatka Creek at Garbutt, affecting Monroe and Genesee counties, until early Thursday afternoon.

Rain and snowmelt have led to rising levels on creeks and rivers. Flows in rivers and creeks will increase and reach critical levels.

For the Oatka Creek, including Garbutt, minor flooding is forecast.

At 4 p.m. Wednesday, the creek was at 5.9 feet. Flood stage is 6 feet.

At flood stage, general flooding of agricultural land begins with some basement flooding in Scottsville and Garbutt, according to the Weather Service.

The river is expected to rise above flood stage late this afternoon to a crest of 6.1 feet this evening. It will then fall below flood stage tomorrow morning.

This crest compares to a previous crest of 6.2 feet on March 19, 2003.

The flood warning has been extended until just after midnight tonight for the Genesee River at Avon, affecting Livingston and Monroe counties, and for the Genesee River, including Wellsville, Portageville, Mount Morris Dam, Avon, Rochester and Honeoye Falls. Minor flooding is occuring and minor flooding is forecast.

At noon Wednesday, the river was at 33.3 feet, the maximum stage in the previous 24 hours. Flood stage is 33 feet, leading to river overflows at many areas from Geneseo to Scottsville, but mainly in agricultural lands with little damage to structures, according to the Weather Service.

The river is expected to rise to a crest of 33.5 feet this afternoon. It will then fall below flood stage this evening.

This crest compares to a previous crest of 33.4 feet on March 6, 1979.

A flood watch remains in effect until 7 tonight for a portion of Western New York, including Allegany, Cattaraugus, Chautauqua, Genesee, Livingston, Monroe, Niagara, Orleans, Wyoming and northern and southern Erie counties.

Flows are already high on many area creeks and rivers, and the combination of snow melt from Tuesdays warm weather and rainfall will cause water levels to rise again. This will bring the risk of flooding along some rivers and creeks due to high flows.

A half to one inch of rain that fell over the region on Tuesday, combined with snow melt from 50 degree temperatures, has led to significant runoff into area tributaries. This will result in rises on larger creeks and rivers, and potentially will cause flooding at some flood prone areas.

There is the potential for a winter storm from Thursday night through Friday that may cause hazardous travel conditions across the GLOW region, and also Monroe, Niagara, Allegany, Chautauqua, Cattaraugus, and northern and southern Erie counties.

This winter storm will have the potential to cause accumulating snow, sleet, and freezing rain.

No advisories have been issues at this time.

A winter storm watch that includes Steuben County will be in effect from late Thursday evening through Friday evening. Heavy snow is possible, with total snow accumulations of 5 to 7 inches.
