Heat Index Could Hit 105 In NoVA, DC: Advisory Issued

Although many kids in the DC area are headed back to school, summer isn't ready to leave just yet. In fact, temperatures will be scorching Tuesday, leading the National Weather Service to issue a heat advisory.

The heat advisory is in effect from noon to 8 p.m. Forecasters expect a heat index up to 105 with temperatures in the mid 90s.

A heat advisory refers to a prolonged period of high temperatures. Combined with high humidity, these conditions make heat-related illnesses more likely. Forecasters caution that long exposure to the conditions outside could cause heat stress.

Anyone who works outside is urged to take caution and limit strenuous activities to the early morning or evening when possible. If outside work cannot be avoided, take frequent rest breaks in shaded or air conditioned environments. Other steps residents can take include wearing loose, light clothing, drinking plenty of water and knowing the signs of heat exhaustion and heat stroke. Call 911 in the situation of heat stroke.

The heat advisory applies to the District of Columbia, Prince William County, Manassas, Manassas Park, Fairfax County, Arlington County, Falls Church, Alexandria, Stafford County and Spotsylvania County. This includes the cities of Dale City, Manassas, Woodbridge, Lake Ridge, Montclair, Reston, Herndon, Annandale, Centreville, Chantilly, McLean, Franconia, Arlington, Alexandria, Falls Church, Falmouth, and Fredericksburg.

The Washington Post's Capital Weather Gang predictsthat Tuesday and Wednesday will be the two hottest days of August. There isn't much chance for relief until Thursday afternoon, when thunderstorms could sweep through the area.
