The National Weather Service in Binghamton is cautioning there is a possibility of poor visibility for motorists Friday morning due to dense fog while rain could dampen some outdoor plans for the last weekend of September.

Forecasters say, with moisture from recent rainfall, locally dense fog developed in many area valleys overnight September 26, especially in the upper Delaware and Susquehanna Valleys.

Officials say visibility may even drop below a quarter mile in some areas at times in the morning.

Travelers should be prepared for rapidly changing visibility. Slow down when encountering dense valley fog, use low beams and allow extra time to reach your destination. Wildlife is also on the move and can be hard to see in the fog.

Meanwhile, the National Weather Service says the first weekend of fall probably is not going to be precipitation-free.

Scattered showers and thunderstorms are forecast for the afternoon and evening September 28.

A few storms could produce strong, gusty winds and heavy downpours.

NOAA says there is a marginal threat for severe weather during this timeframe.
