The City is closely monitoring the Air Quality Index (AQI)
in Palo Alto, and the Library is aligning with the City’s operational policies. The AQI is fluctuating between Yellow/Moderate to Red/Unhealthy today and is forecasted to remain at these levels through Friday, August 28. When air quality is Yellow, or Moderate, air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution. Elderly persons, children, and individuals with respiratory illnesses are particularly susceptible to elevated air pollution levels and should take extra precautions to avoid exposure.
