According to Middle Atlantic River Forecast Center estimates, no rain fell in the basin over the past 24 hours. Between 0.01 and 1.25 inches of rain is forecast over the next 7 days.
The USACE's recreational release has passed the Point of Rocks gage and flows at that gage have dropped below 2000 cfs again. MARFC's GEFS predictions are suggesting that some of the precipitation forecast may affect the Point of Rocks gage flow between October 7 and 11, causing flows at that gage to increase slightly.
