DUE TO THE ARRIVAL OF A FEW ATMOSPHERIC RIVERS, JUNEAU SET MULTIPLE DAILY PRECIPITATION RECORDS. RECORDS WERE SET ON 10TH (1.73", PREVIOUS 1.53" SET IN 1961), 14TH (1.24", PREVIOUS 0.84" SET IN 1989), 15TH (1.22", PREVIOUS 1.06" SET IN 1978) AND 17TH (1.80", PREVIOUS 1.22" SET IN 1963). YAKUTAT AND SITKA SET NEW PRECIPITATION RECORDS ON THE 13TH (1.74", PREVIOUS 1.62" SET IN 2015 AND 2.35" PREVIOUS 1.86" SET IN 1969...RESPECTIVELY) AND 14TH (2.15", PREVIOUS 2.15" SET IN 1941 AND 1.31", PREVIOUS 1.21" SET IN 1987...RESPECTIVELY). BY THE END OF THE MONTH JUNEAU FINISHED WITH 12.21" OF RAINFALL, WHICH BROKE THE PREVIOUS MONTHLY RECORD OF 10.40" PREVIOUSLY SET IN 2015. SITKA REACHED THE 3RD WETTEST, WHILE YAKUTAT WAS THE 18TH WETTEST. HIGHLIGHTING THIS PATTERN, JUNEAU HAD 6 DAYS THAT COLLECTED OVER 1" OF RAINFALL. DURING JULY, HEAVY RAINFALL FROM A FEW ATMOSPHERIC RIVERS AND SNOW MELT FROM WARM HIGH TEMPERATURES CONTRIBUTED TO FLOODING ON THE TAIYA AND CHILKAT RIVERS NEAR SKAGWAY AND HAINES FOR MULTIPLE DAYS. AN ASSORTMENT OF RIVERS, CREEKS AND STREAMS IN THE JUNEAU AREA ALSO REACHED MINOR FLOOD STAGE DURING THE MONTH. NARRATIVE: VAUGHAN CLIMATE DATA QC: CHAMBERS $$
