(Weather Underground) – The remnants of former Hurricane Rosa made their presence felt across far northwest Mexico and the Southwest U.S. on Tuesday. Phoenix picked up 2.36”, which makes Tuesday the wettest October day in the city’s 123 years of weather records (beating 2.32” from October 14, 1998). Tuesday also ranks as the eighth-wettest calendar day on record in Phoenix. Totals of 2” – 3” across the Phoenix metro area led to widespread flash flooding, and there was a CoCoRaHS report of 3.45” just south of Flagstaff. The largest rain total from Rosa’s remnants through 3 am EDT Wednesday was 6.89” at Towers Mountain, Arizona—still well short of the state record for storm totals associated with a tropical cyclone (12.01” from Nora in 1997).
