Heat index values could reach 105 degrees Fahrenheit in Reston on Wednesday, and the community's busiest library won't be available as a cooling center.
The National Weather Service issued a Heat Advisory for Fairfax County, including Reston, in effect from 11 a.m. to 8 p.m. Wednesday. Forecasters predict highs of 99 degrees, with humidity pushing the heat index to dangerous levels. The advisory warns that hot temperatures and high humidity may cause heat illnesses.
Reston Regional Library remains closed
Reston Regional Library at 11925 Bowman Towne Drive has been shut down since the week of July 7 for heating, ventilation and air conditioning (HVAC) repairs. The closure was initially expected to end Tuesday, but a Fairfax County Public Library spokesperson told FFXnow the reopening was postponed "due to a delay in receiving the necessary materials" for the repairs.
The library is now expected to remain closed through at least July 20. The branch, which FCPL describes as one of its busiest, typically serves as an air-conditioned refuge during extreme heat events.
Where to cool off
An FCPL spokesperson confirmed several alternative cooling locations near Reston:
- Herndon Fortnightly Library
- Great Falls Library
- Reston Human Services Building
- Cathy Hudgins Community Center
- Sully Community Center
- Lake Anne Human Services office
Fairfax County had not activated its formal heat plan as of Tuesday evening, July 14. Residents can check the county's extreme heat resources page at fairfaxcounty.gov/topics/extreme-heat-resources for updates on cooling center availability.
If the power goes out
Fairfax County's Department of Emergency Management and Security published guidance on Tuesday, July 14, focused on handling heat during a power outage. The county advises residents to stay hydrated, close blinds and curtains to block sunlight, unplug unused electronics, and limit use of ovens and stoves.
If indoor temperatures climb above 90 degrees during an outage expected to last several hours, the county said residents should leave for a cooler location rather than wait it out.
Forecasters predict highs near 99 degrees again on Thursday, July 16, meaning demand for cooling centers may extend beyond the advisory window.
