Flash flood watch is in effect through Friday afternoon for Ontario, Wayne, Monroe and nearby counties

Heavy rains Thursday, coupled to rainfall from the night before, have made for some treacherous travel in the western and central New York area — and it’s not quite over.

A flash flood watch is in effect through Friday afternoon for portions of western and north central New York, including Ontario, Wayne, Monroe and nearby counties. Widespread showers and thunderstorms producing heavy rain continued to move across the region Thursday, and the National Weather Service noted that another area of low pressure moving across the area Thursday night would elevate the flash flood potential across the region into Friday.

The wet stuff will keep coming Friday, as the NWS projects heavy rain and patchy fog throughout the day, followed by likely showers at night. A reprieve from the rain is expected Saturday, though Sunday brings a slight chance of showers and a 50 percent chance of thunderstorms later in the day.

A flash flood watch means the threat of flash flooding exists along rivers and creeks, according to the NWS, which advises people in the watch area to be ready to move to higher ground if flooding is observed or a warning is issued.
