THE WETTEST AUGUST...SEPTEMBER...OCTOBER ON RECORD IN THE TWIN CITIES IS JUST OVER 
18 AND A HALF INCHES //18.63//...SET IN 1900.
THE CURRENT 3 MONTH PRECIPITATION TOTAL IS THE SECOND WETTEST ON RECORD AT JUST OVER 18 INCHES //18.06//. 
THAT IS ABOUT 6 TENTHS OF AN INCH //0.57// UNDER THE CURRENT NUMBER ONE.
