August 27 Update: Added chart of 30-day precipitation.
Original post:
Hurricane Irene has not yet arrived, and this month is already the rainiest on record at Phildelphia in climate records which extend back to 1872. The National Weather Service reported this morning on the new precipitation record:
..RECORD MONTHLY RAINFALL AT PHILADELPHIA
WITH THE 0.61 INCHES OF RAIN THAT FELL AT PHILADELPHIA INTERNATIONAL
AIRPORT YESTERDAY, THE AUGUST MONTHLY TOTAL NOW STANDS AT 13.61 INCHES.
THIS SURPASSED THE PREVIOUS AUGUST RECORD OF 12.10 INCHES, WHICH WAS
SET BACK IN 1911.
THIS ALSO MAKES AUGUST 2011 THE ALL TIME WETTEST MONTH ON RECORD
BREAKING THE OLD RECORD OF 13.07 INCHES, WHICH OCCURRED DURING
SEPTEMBER 1999 /MOSTLY HURRICANE FLOYD/.
WITH HURRICANE IRENE MOVING UP THE EAST COAST, ADDITIONAL RAINFALL
WILL PUSH THESE RECORDS HIGHER.
