THE MONTH OF APRIL FOR ANNETTE ISLAND, AK WAS VIRTUALLY A AVERAGE MONTH WITH A 
SMALL ABUNDANCE OF RAIN BEING THE ONLY EXCEPTION.  THE AVERAGE TEMPERATURE WAS 45.2 
DEGREES F (FAHRENHEIT) WHICH WAS NEARLY THE MONTHLY AVERAGE BEING JUST A DEGREE F 
HIGHER. THE MONTH WAS ALSO FAR FROM BREAKING ANY TOTAL MONTHLY RECORDS.  HOWEVER, 
WIND DID PLAY A BIG PART OF THE MONTH DUE TO MANY STORM FORCE SYSTEMS THAT FAST 
TRACKED THROUGH THE AREA, ONE OF WHICH DID BREAK A RECORD.

TEMPERATURE WISE WAS NOT TOO EXCITING.  THE AREA REACHED A COMFORTABLE 63 DEGREES F 
ON THE 24TH FAR FROM THE RECORD MAXIMUM HIGH OF 82 DEGREES F AND ON THE COLDER SIDE 
THE AREA DROPPED DOWN TO A BRISK FREEZING 32 DEGREES F ALSO FAR FROM THE RECORD LOW 
OF 21 DEGREES F.  OVERALL A AVERAGE MONTH AND NO SIGNS OF GLOBAL WARMING FOR THIS 
APRIL.

ON THE PRECIPITATION SCALE APRIL SHOWERS ONLY BROUGHT ON 15 OUT OF THE 30 DAYS WITH 
A SIGNIFICANT AMOUNT OF RAINFALL MEASURING 0.10 INCHES OR GREATER. THERE WERE 20 
OUT OF 30 DAYS WITH AT LEAST A TRACE OF RAIN COMPARITIVELY LOW TO THE LAST COUPLE 
OF MONTHS.  A TOTAL OF 11.84 INCHES, HOWEVER, WAS FAIRLY ABOVE THE STANDARD 6.77 
INCHES, BUT FAR FROM THE RECORD 21.35 INCHES SET BACK IN 1949.  LAST YEARS TOTAL 
CAME IN AT 15.60, SO NOT AS RAINY, BUT AT LEAST HALF A DOZEN DAYS OF HEAVY RAIN 
SHOWERS BROUGHT US TO A RELATIVELY WETTER THAN USUAL MONTHLY TOTAL.  THE AREA DID 
BREAK A DAILY RECORD HIGH ON THE 12TH OF 1.07 INCHES OF RAINFALL, BUT THE GREATEST 
24 HOUR TOTAL WAS FOR 2.12 INCHES THAT FELL ON THE 9TH. 

ON THE FROZEN PRECIPITATION SPECTRUM THE AREA ONLY RECIEVED A TOTAL TRACE AMOUNT 
SPANNING OVER A FEWS DAYS FROM ISOLATED MICROSCALE EVENTS OF ICE PELLETS.  IN 
CONCLUSION, NOT A LOT OF SNOW FELL OVER THE ENTIRE AREA, BUT ON THE OTHER HAND SOME 
FORM OF FROZEN PRECIPITATION DID FALL IN SECLUDED AREAS.  THIS IS NOT TOO FAR FROM 
UNUSUAL WITH APRIL HAVING AN AVERAGE OF JUST 1.4 INCHES OF SNOWFALL AND THERE ARE 
PREVIOUS YEARS WITH NO SNOWFALL BEING REPORTED WHATSOEVER. 

FINALLY, THE WINDY FACTOR DID NOT SEEM TOO FAR FROM NORMAL NONETHELESS THE AREA DID 
RECEIVE SOME STRONG WIND EVENTS THROUGHOUT THE MONTH.  THE AVERAGE WIND SPEED WAS A 
MERE 7.7 MPH (MILES PER HOUR) WHICH WAS AVERAGE.  HOWEVER, HALF A DOZEN DAYS OF 
STRONG WIND EVENTS OF 45 MPH OR GREATER PUT OUT SOME HIGH NUMBERS.  MAXIMUM WINDS 
REACHED 73 MPH ON THE 28TH DUE TO A HURRICANE FORCE LOW PRESSURE SYSTEM IN THE 
AREA.  THIS SYSTEM PUT ANNETTE ON THE RECORD BOOK REACHING 7TH ON THE ALL TIME HIGH 
LIST, BUT FAR FROM THE 150 MPH RECORD ON 9/3/2011.  THE SYSTEM DID PUT ITSELF IN 
THE RECORD BOOKS FOR THE ALL TIME HIGH WITHIN APRIL.  THERE WERE 4 DAYS THAT MADE 
IT TO THE TOP 50 LIST FOR HIGHEST WIND SPEED AVERAGE IN APRIL WITH THE HIGHEST 2 
DAYS BEING 16.7 MPH AND 16.3 MPH ON THE 9TH AND 28TH, RESPECTIVELY.
