| episode_narrative | High pressure was the dominant weather feature across the Washington D.C. metropolitan area through the 24th of August. Most rain producing storm systems steered north of the region through the period. This resulted in the continuation of the climotological, meteorological, and hydrological drought which has plagued the area since last summer. Heavy rain fell across the District on the 25th and 26th, helping to fill surface reservoirs. Unfortunately, because most of the rain fell in the form of thunderstorm downpours, most of the moisture ran off into the rivers before it had the chance to seep into the aquifer supply. Groundwater reserves remained unaffected and wells remained short of water. High temperatures were at or above 90 degrees through the 19th then cooled into the 70s and 80s for the remainder of the month. By the 26th o f August the Palmer Drought Index, a measure of long term drought conditions, indicated Washington D.C. was in an extreme drought. From September 1998 through August 1999 precipitation was a staggering 16 inches below average. Washington Reagan National Airport reported 5.02 inches of rain in August, 1.11 inches above normal. However, 3.40 inches of this total fell on the 25th and 26th. The lack of rain through the third week of August continued to affect water levels along the Potomac River, the main water source for the Washington area. The flow of water past Washington was below average for the 12th consecutive month. Through the third week of August the average daily flow of the river was only 11% of normal. Water was released from the Jennings Randolph Reservoir in the headwaters of the Potomac River on the 11th to boost water levels. |
