The torrential rains that flooded parts of the District on Sunday were absent Monday, but humid, moisture- laden air, suggestive of the tropics, remained in the Washington region, producing clammy conditions and another waterspout.

The National Weather Service said Coast Guard personnel reported the spout, regarded as a tornado over water, near Deal Island, Md., on the eastern side of the Chesapeake Bay about 12:20 p.m. Monday.

It was spotted in an area where the weather service warned of a line of thunderstorms that were capable of producing a spout.

On Sunday evening, a waterspout was spotted in the Back River area, near Baltimore.

Meanwhile, official figures indicated that much of the region missed the downpour that flooded the District’s Bloomingdale and LeDroit Park sections.

Sunday’s official rainfall total at Reagan National Airport was .05 inch. On Monday, only a trace of rain was reported there by 5 p.m. At Dulles International Airport , 0.39 inch fell Sunday, none Monday.
