A hazardous weather outlook for portions of Western New York, including Genesee County, has been issued by the National Weather Service in Buffalo.
An "upper-level disturbance" is moving across the region today and will generate some showers and thunderstorms, some of which will include slow-moving downpours.
Since there will be the risk for multiple slow-moving downpours over the same area ("training storms"), there will be an increased risk for localized flash flooding.
By Thursday, a slow-moving cold front will cross Western New York and numerous showers and thunderstorms will occur along and ahead of this cold front, which will likely produce significant rain.
