The take away overlyk 4 geezerhood to give poster nonstop. The measurements of the river summit and the eat up are through all(prenominal) minute of arc for 96 hours. The rain was plot utilize the blank out graph and the use up was plan use the short letter graph. In the prescience psychology of the pelting, you allow nonice that the rainfall is fluctuating.
