...RECORD-SETTING WET DAY ACROSS THE FLORIDA KEYS YESTERDAY...

Tropical Storm Sally passing north of the Florida Keys, later
assisted by thunderstorm outflow moving north across the Straits
of Florida from Cuba, resulted in one of the wettest days for the
island chain in the past 10 to 15 years. The day was marred by
significant flooding, first in the Upper Keys during the morning
and then Key West and the Lower Keys during the evening. Flooding
resulted in numerous road closures, stalled vehicles, and water
entering multiple residences and businesses.

Of note, the 11.36 inches of rainfall measured at the Florida Keys
NWS office on White Street in Key West is the wettest day on record,
since observations at the facility began in September 2007. While
this may be a short period of record, it is significant in that it
was over 4 inches greater than the next wettest day, 7.00 inches on
October 23, 2008.

For the Key West climate location (Key West International Airport
ASOS) 9.37 inches of rainfall was a dual record. It shattered the
daily record for September 12 of 2.26 inches from 1924. It is also
now the wettest September day on record, surpassing the previous
record of 7.47 inches on September 10, 1919. In addition to these
two new titles, it became the 5th wettest day ever recorded in the
Key West area, with records dating back to 1871. The wettest day on
record for Key West is November 11 1980, when 22.75 inches of
rainfall was measured.

The Marathon climate location (Florida Keys Marathon International
Airport) was not to be left out, also setting new records for
September 12 and any September day. Yesterday`s rainfall total of
8.13 inches was more than 7 times the previous daily record of 1.13
inches set in 1995. Until yesterday, the wettest September day was
September 28, 1953, when 5.92 inches of rainfall was measured. With
records going back to 1950, yesterday also ranks as the 3rd wettest
day ever recorded for the Marathon area. August 24, 1995 remains the
wettest day on record for Marathon, with 8.33 inches of rainfall. A
record that was very much in jeopardy yesterday.
