Thursday September 2
Following the historic rainfall on Wednesday, we continue to monitor the water that flows down rivers.
This report is focusing on The Monocacy River in Frederick County and The Susquehanna River in Northeastern Maryland. There are two separate Flood Alerts this morning in Northeastern Maryland I wanted to pay extra attention to.
- Flood Warning in Frederick along the Monocacy River- At Major Flood Stage.
- Flood Watch for The Conowingo Dam- Still Rising.
- Flood Warning in Harford and Cecil Counties.
Preliminary rainfall estimates show a large coverage from central Maryland and north with over 5 inches of rain. Upstream there are many areas that received over 7 inches of rain.
Much of this water has to flow down to the Chesapeake Bay and out to the Atlantic.
