As the area remains embroiled in a heat wave, the National Weather Service has again issued a heat advisory that will be in effect Thursday from noon to 7 p.m.

According to the NWS alert:

The National Weather Service in Baltimore MD/Washington has
issued a Heat Advisory, which is in effect from noon today to
7 PM EDT this evening.

* HEAT INDEX VALUES…Up to around 105 degrees.

* IMPACTS…The heat and humidity may cause heat stress during
outdoor exertion or extended exposure.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A Heat Advisory means that a period of high temperatures is
expected. The combination of high temperatures and high humidity
will create a situation in which heat illnesses are possible.

Take extra precautions if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work, the Occupational Safety and
Health Administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency — call 911.

Heat advisories were issued last week as temperatures neared triple digits, as they are expected to do again in coming days.

Residents are encouraged to avoid any activity that keeps them in the extreme heat for lengthy periods of time. Anyone who must be outside in the heat should know the signs of heat-related illness.

Anyone who finds themselves in extreme distress because of a lack of air-conditioning or other means to keep themselves cool can seek the assistance of a county-designated cooling center. Local centers include the Reston Regional Library and Southgate Community Center.
