the number of storms involving heavy precipitation. Elk River is projected to have an increase of <br />over 1.2 days with extreme precipitation (the top 2% of storms). As the number of storms and <br />heavy precipitation increase, the risk, and reality, of flooding also increase. The three factors <br />affecting flooding are rainfall, snowmelt, and rate of runoff. The two major types of flooding <br />expected in the future are flooding from snowfall (majority occurring in the form of lake effect <br />snowfall) and flooding from extreme precipitation. Contrastingly, surnmer precipitation is <br />expected to decrease. An overall 8% decrease in summer precipitation in 2041-2062 (relative to <br />1979-2000) is expected for the Midwest" (NCA). The number of consecutive days each year <br />with less than 0.01 inches of precipitation is expected to increase by about 1-2 for the City of Elk <br />River. <br />All in all, precipitation is a topic to keep in mind when considering mitigating a city in <br />preparation for climate change, and after looking at past trends and current projections, it is clear <br />that an increase in spring and winter and a decrease in summer precipitation will have a wide <br />range of effects on the city of Elk River. <br />
