...WARM APRIL AT KING SALMON ALASKA...

THE BRISTOL BAY AREA EXPERIENCED ABOVE NORMAL TEMPERATURES FOR MOST OF THE 
MONTH OF APRIL. THE MAIN DOMINANT WEATHER FACTOR INFLUENCING THE WEATHER 
OVER KING SALMON WAS A SERIES OF LOW PRESSURE CENTERS PASS THROUGH SOUTH OF 
THE ALASKA PENINSULA SETTING UP A PERSISTENT EASTERLY TO SOUTHEASTERLY 
FLOW. THIS WARM FLOW KEPT TEMPERATURES ABOVE NORMAL FOR MOST OF THE MONTH. 
PRECIPITATION TRANSITIONED FROM SNOW AND RAIN THE FIRST PART OF THE MONTH 
TO LIGHT RAIN FROM MID MONTH TO THE END OF THE MONTH. HIGHEST TEMPERATURE 
FOR THE MONTH WAS 60 DEGREES FAHRENHEIT ON 26 APRIL AND THE LOWEST 
TEMPERATURE WAS 16 DEGREES FAHRENHEIT ON 12 APRIL. THE AVERAGE MONTHLY WIND 
SPEED WAS 10 MPH. THE HIGHEST SUSTAINED WIND WAS ON THE 18TH WITH A 
SOUTHEASTERLY WIND OF 35 MPH. THE HIGHEST SINGLE GUST OF 42 MPH ALSO 
OCCURRED ON THE 18TH.  

NEW RECORDS...
A DAILY PRECIPITATION RECORD ON THE 6TH OF APRIL OF 0.63 INCHES BREAKS THE 
OLD MARK OF 0.24 INCHES SET IN 1935.

RECORD SNOWFALL AMOUNTS WERE ALSO SET ON THE 7TH OF 2.5 INCHES BREAKING THE 
OLD RECORD OF 2.0 INCHES SET IN 1931...THE 8TH OF 4.5 INCHES BREAKING THE 
OLD RECORD OF 2.7 INCHES SET IN 1975...AND THE 9TH OF OF 3.8 INCHES 
BREAKING THE OLD RECORD OF 2.2 INCHES SET IN 1974.
