AUGUST IS NORMALLY A WARM AND WET MONTH FOR YAKUTAT AND THIS WAS NO EXCEPTION. A
DEFINING TRAIT OF AUGUST IS PERIODIC SYSTEMS OF TROPICAL ORIGIN THAT BRING HEAVY
RAINFALL OVER ONE OR TWO DAYS. THIS MONTH HAD A SYSTEM MOVE THROUGH ON THE 17TH
THAT BROUGHT HEAVY RAIN TOTALING OVER 4 INCHES AND RISK FOR FLOODING OVER SE
ALASKA. THE REST OF THE MONTH WAS STITCHED BETWEEN RAIN AND FAIR WEATHER AND
ALIGNED WITH EXPECTED CLIMATE FOR THE PERIOD.
