| episode_narrative | High pressure was the dominant weather feature across the Washington D.C. metropolitan area during the month. This weather pattern directed rain producing low pressure systems north of the region and continued the climatological drought that has gripped the area since last summer. By the last week of June the Palmer Drought Index, a measure of long term drought conditions, indicated Washington D.C. was in a severe drought. June was the 8th month in the past 12 months that precipitation was below normal. From July 1998 through June 1999 precipitation was a staggering 14 inches below average, the 3rd driest 12 months on record. Washington Reagan National Airport reported a monthly total of 2.26 inches, 1.12 inches below normal. Measurable rain only fell on 8 days during the month, and 1.32 inches of the total fell ont he 16th. The lack of precipitation affected water reserves. The flow of water down the Potomac River at Washington D.C. hovered around 18% of average, and many new record low daily flows were recorded in upstream tributaries of the river. Monthly flow rates along the basin have been below average for the last 10 months. Unusually high proportions of river flow, 33%, were diverted from the river into public water supplies during the month. The normal diversion rate is about 5%. |
