“Flooding caused by heavy rainfall continues to be possible,” the National Weather Service stated in its flood watch. “Excessive runoff from heavy rainfall may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas. Area creeks and streams are running high and could flood with more heavy rain.”

Spear warned Bay Staters to expect up to 3 inches of rain in some places, heavy at times, with the chance of embedded thunderstorms.
