Washington's temperatures reached the 90s yesterday for the ninth consecutive day, and forecasters said the sticky weather will continue today, Potomac River watchers said things could be worse.
Frank Forrester, of the U.S. Geological Survey, said the afternoon and evening showers and thunderstorms that have accompanied the hot spell have kept the flow in the Potomac River well above the amount of water the Washington area draws from the river each dat.
Although the summer has been drier than usual, and the average river flow of 1.2 billion gallons a day so far this month is 40 per cent below normal, it is well above the average demand of 350 million gallons a day.
"We can be thankful for these showers," Forrester said.
There is a good chance of more showers today, according to National Weather Service forecasters who predicted more of the same weather that brought a high temperature of 91 degrees yesterday at National Airport at 12:05 p.m.
A record of sorts was matched on Thursday, when the mercury faileed to fall below 76 degrees all day. The 76 degrees is the highest low temperature for Aug. 11 ever recorded here. The last previous such reading was on Aug. 11, 1973.
