...REMARKS...UNDENIABLY THE BIGGEST EVENT OF THE MONTH WAS THE
RECORD RAINFALL OF 2.59 INCHES ON THE 24TH. THIS WAS NOT ONLY THE
DAILY RECORD...PREVIOUSLY SET AT 0.57 INCHES IN 1904...BUT IT ALSO
BROKE THE DAILY RAINFALL RECORD FOR THE MONTH OF SEPTEMBER WHICH WAS
PREVIOUSLY SET AT 2.44 INCHES ON THE 11TH IN 1895. THIS RAINFALL WAS
DUE TO A WARM WEATHER SYSTEM THAT STALLED OVER THE AREA FOR AROUND
18 HOURS. ASIDE FROM A FEW SHOWERS BEHIND THIS SYSTEM AND ONE WEAK
SYSTEM EARLIER IN THE MONTH THE MONTH WAS MAINLY DRY.

ALSO NOTABLE WERE THE ABOVE NORMAL TEMPERATURES. THE AVERAGE HIGH
TEMPERATURE FOR THE MONTH ENDED UP 2.4 DEGREES ABOVE NORMAL. THERE
WERE 4 DAYS ABOVE 70 AND ONE DAY WE TOPPED AT 80 DEGREES. LOW
TEMPERATURES WERE ALSO A COUPLE DEGREES ABOVE NORMAL...ALTHOUGH
THERE WERE SOME CHILLY NIGHTS.  TWO LOW TEMPERATURE RECRODS WERE
TIED. A LOW OF 59 DEGREES ON THE 18TH TIED THE HIGHEST LOW...LAST
SET ON THE 18TH  IN 1990. A LOW OF 46 ON THE 4TH TIES THE OLD RECORD
LOW FOR THE DATE LAST SET IN 1996. ALL THIS WEATHER WAS DUE TO WARM
OCEAN WATER TEMPERATURES AND PERIODIC OFFSHORE FLOW.
