...WET IN THE NORTH AND DRY IN THE SOUTH WITH NEAR NORMAL
TEMPERATURES FOR JULY...

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.
