In the past 24 hours, the Middle Atlantic River Forecast Center (MARFC) measured zero precipitation in the basin. The 48-hour forecast shows no chances of precipitation across the basin. The 5-day forecast indicates that the basin may receive between 0.75 to 2.3 inches of accumulated precipitation. MARFC does not forecast precipitation around the basin until possibly this Saturday or Sunday.
The lack of precipitation has caused Point of Rocks flow to drop below the 2,000 cfs threshold again.
