Below average rainfall for 2009?
Posted by Ed C on Tuesday, May 26, 2009
Waiting for a break in the rain so I could walk the dog, and WBAL just announced a flash flood warning for Howard County.
I began wondering just what kind of records we were setting for rainfall. As of yesterday (5/25/09) BWI was about 1″ less than normal for the year (according to the National Weather Service). Since Jan 1st, we have received 15.67 inches of precipitation while the average is 16.55 inches.
Looking at just May, so far we had received 4.81 inches, while in 2008 we received 7.77 inches for the entire month, and the record for May appears to be 8.71 set in 1989.
The one month record is 18.35 inches in Aug, 1955.
And just for comparison, the average yearly rainfall for Seattle, WA is 38.25 inches while at BWI it is 41.94 inches. Go figure.
