Vienna residents face another heat advisory from 11 a.m. to 9 p.m. Wednesday.
Temperatures will reach about 97 degrees, but it will feel much hotter: the Heat Index Value—the perceived temperature—will be around 105 degrees.
The National Weather Service forecast for Vienna calls for a sun until about 2 p.m., when a 40 percent chance of rain begins.
The combination of hot temperatures and high humidity will make heat illnesses possible. The NWS advises drinking lots of fluids and staying out of the sun. Elderly relatives and neighbors should be checked on, and extra precautions should be taken for children and other sensitive groups. If possible, avoid work outdoors or reschedule outdoor activity to the early morning or late at night.
Due to the high temperatures, Metro and the Fairfax Connector system will allow riders to drink water on board trains and buses.
