Over 6 weeks remains in #Monsoon2021 & Tucson's total of 11.30" ranks as the 3rd wettest on record. The all-time record is 13.84" from 1964. Normal rainfall for the remainder of the season (Aug 15 to Sep 30) is 2.33" So based on normal rainfall the record is reachable. Hmm. #azwx pic.twitter.com/CFtMxzmihJ— NWS Tucson (@NWSTucson) August 15, 2021
Scattered showers & thunderstorms today, mainly E & S of Tucson. Brief heavy rain still a threat w/any storm. Ground is very saturated after previous rainfall & any additional heavy rains could lead to flash flooding. Thus a Flash Flood Watch remains in effect today. #azwx— NWS Tucson (@NWSTucson) August 15, 2021
