A flood watch has been issued for the Pittsburgh area this weekend due to anticipated heavy rainfall, as reported by CBS News. The forecast predicts significant precipitation, potentially leading to flooding in low-lying areas and near rivers. The National Weather Service has put the flood watch into effect from Saturday morning through Sunday evening, citing concerns over rainfall totals of 1 to 3 inches, with the possibility of even higher amounts in some localized areas. This level of rainfall within a short time frame could overwhelm drainage systems and cause rapid rises in rivers and streams.
