Wider weather episode

The remnants of Ida produced widespread flooding along with instances of flash flooding across the area. Tropical moisture infiltrated the area and there were moderate amounts of instability as well. This combined with the lift provided from the remnants of Ida led to heavy rainfall during this time. Rainfall amounts averaged around 1-3 near and east of Interstate 95, with amounts around 4 to 8 inches across portions of northern and central Maryland. Excess runoff from the heavy rainfall led to river flooding as well.
