Advisory For All Fall Ball Participants

Fall Ball Participants,

Just an advisory that the air quality is currently in the moderate range and will be in the “unhealthy for sensitive groups” range for the rest of the week due to the numerous wildfires happening throughout the area. As of now, we leave it up to the coaches and parents to decide whether to practice. If the air quality worsens, we may be forced to cancel practices.

You can find up to date air quality information at I have attached the upcoming week predictions as well as what each category means.

*The use of medical and cloth masks are not effective for filtering smoke particles. N95 masks are more effective, but are probably not recommended for children playing sports.

We ask that if you are not going to practice, please let your coaches know out of courtesy. The Fall Ball rosters are smaller in order to adhere to the social distancing guidelines.

I know everybody is looking forward to seeing friends, meeting their teammates, and getting back on the field. We want everybody to be as safe as possible!

Thank you,

Scott Fujimoto

NWLL Safety Officer

Understanding the AQI

The purpose of the AQI is to help you understand what local air quality means to your health. To make it easier to understand, the AQI is divided into six categories:

Each category corresponds to a different level of health concern. The six levels of health concern and what they mean are:

  • "Good" AQI is 0 to 50. Air quality is considered satisfactory, and air pollution poses little or no risk.
  • "Moderate" AQI is 51 to 100. Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms.
  • "Unhealthy for Sensitive Groups" AQI is 101 to 150. Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
  • "Unhealthy" AQI is 151 to 200. Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects.
  • "Very Unhealthy" AQI is 201 to 300. This would trigger a health alert signifying that everyone may experience more serious health effects.
  • "Hazardous" AQI greater than 300. This would trigger a health warnings of emergency conditions. The entire population is more likely to be affected.
