It’s 92 degrees in D.C., though it feels a bit hotter than that. The National Weather Service puts the local heat index at 96 degrees as of about 3 p.m., enough to trigger a heat emergency.

The District’s Homeland Security and Emergency Management Agency issues a heat emergency whenever the heat index reaches 95 degrees. Today’s advisory is actually the second of this summer; the first coming yesterday when the index touched 97 degrees. Today’s heat emergency went into effect at 2:12 p.m.

When heat emergencies are in effect, residents are advised to stay indoors, preferably where air conditioning is available, limit exposure to the sun, keep pets and children inside, and drink lots of water. Robyn Johnson, a spokeswoman for HSEMA, says agency is still finalizing its 2013 heat emergency guide; the 2012 edition is still available online.

Residents who do not have access to air conditioning can cool off at one of the Department of Parks and Recreation’s facilities, such as city pools, or in other public buildings.

Officials expect to declare another heat emergency tomorrow, when the forecasted high is 94 degrees.
