Longest bout of rain was in 1873

Rain floodFROM TODAY'S PRINT EDITIONS:

Charles Davis writes from Baltimore with a Biblical query: “Has Maryland ever experienced a period of 40 days and 40 nights of rain?” Not by a long shot, at least not in Baltimore since official records began in 1871. NWS science officer Steve Zubrick said: “The longest consecutive stretch of days having measureable (0.01 inch or more) precipitation is 14 days.” That occurred from Aug. 10 to 23, 1873, with 8.81 inches in the gauge by the time it let up.  Nearly 4 inches fell Aug. 13.

Frank,

Better question is if it has ever happened anywhere on the planet other than Noah's time.

Or anywhere close ??

Fran In Baltimore

FR: A better question, perhaps, but reliable global data going back 6,000 years is hard to come by.

What about October 2005? I thought it rained nearly everyday that month. We had 14" of rain that month in the Baltimore area.

FR: That was a very wet month, with 9.23 inches recorded, officially, at BWI-Marshall. That's still the record for October. There were two days in a row that delivered 6.65 inches. In all, the airport saw 10 days of measurable rain that month (and six more days with a trace), but no more than three days in a row with 0.01 inch or more.
