Update: Heavy Rains Over Small Area Cause Flood Warnings


Most of Labor Day weekend was a washout for folks who live in the Oswego-to-Mexico corridor.

A rainstorm that spanned two days put as much as 3 inches of fresh rain on the ground through Sunday.

The National Weather Service reports that 2.57″ of rain fell in Oswego, as reported by a cooperative weather observer. An observer in Volney reported 3.12″ of rain.

The band of rain was narrow and it stayed put for many hours Saturday into Sunday. It doused the corridor from Oswego to Mexico, but left most other areas of the county alone.

Over the same time period as the storm, for example, only 3-tenths of an inch of rain was recorded at the automated weather station at the county airport in Volney.

The heavy rain caused the National Weather Service to issue a flood advisory for the affected area, as small streams and low-lying areas could have been overrun with water.

No incidents were reported to police related to the wet weather.

From the National Weather Service

The National Weather Service in Buffalo has issued an urban and small stream flood advisory for Oswego County in Central New York until 1:15 p.m. At 8:19 a.m., National Weather Service Doppler radar indicated a band of heavy lake effect rain over central Oswego County. Doppler radar estimates that up to 3 inches of rain has fallen overnight along the route 104 corridor from Oswego and Scriba east through Mexico. The band of lake effect rain is expected to remain nearly stationary for several more hours this morning before lifting north by midday. Additional rainfall amounts of 1 to 2 inches are possible in localized areas along route 104 from Oswego east through Mexico and Williamstown. Excessive runoff from heavy rainfall will result in rapid rises on small streams and creeks. Minor flooding is likely in low lying and poor drainage areas.

Instructions: most flood deaths occur in automobiles. Never drive your vehicle into areas where the water covers the roadway. Flood waters are usually deeper than they appear. Just one foot of flowing water is powerful enough to sweep vehicles off the road. When encountering flooded roads make the smart choice: Turn around — don’t drown.
