Flood risk and historical context
According to the Baltimore Office of Sustainability, Baltimore’s regulated floodplain includes areas with 1% and 0.2% annual chances of flooding, also known as the 100-year and 500-year floodplains. The verified citywide information cited here does not identify specific neighborhoods.
As a separate historical example, the National Weather Service Baltimore/Washington office reports that during the remnants of Tropical Storm Lee in September 2011, Baltimore-Washington International Airport (BWI) had several daily rainfall records broken and tallied 13.32 inches for the wettest September on record. That is historical context, not a rainfall projection for this Sunday.
Columbus Day Starts Unsettled
Monday brings a 70% chance of rain showers and a high near 74. Conditions should improve Monday night, with partly cloudy skies and a low around 62, before Tuesday turns partly sunny near 73 degrees.
