|
Extreme
|
"An Extreme Threat to Life and Property from Dense Fog or Smoke."
Widespread very dense fog or smoke with the predominate visibility near zero and the coverage greater than 55% within a defined area, persisting for at least 1 hour.
|
|
High
|
"A High Threat to Life and Property from Dense Fog or Smoke."
Areas of very dense fog or smoke with the visibility near zero and the coverage 25 - 54% within a defined area, persisting for at least 1 hour.
|
|
Moderate
|
"A Moderate Threat to Life and Property from Dense Fog or Smoke."
Widespread dense fog or smoke with the predominate visibility 1/8 - 1/4 mile and the coverage greater than 55% within a defined area, persisting for at least 1 hour...OR...patchy very dense fog or smoke with the visibility near zero and the coverage less than 25% within a defined area, persisting for at least 1 hour. Surrounding fog may or may not be present.

Low
|
"A Low Threat to Life and Property from Dense Fog or Smoke."
Areas of dense fog or smoke with the visibility 1/8 - 1/4 mile and the coverage 25 - 54% within a defined area, persisting for at least 1 hour.
|

Very Low
|
" A Very Low Threat to Life and Property from Dense Fog or Smoke."

|
Non-Threatening
|
" No Discernable Threat to Life and Property from Dense Fog or Smoke."
Visibility greater than 1/4 mile and non-threatening. Fog/smoke may still be present, but not dense.
|
| Note: Fog or smoke becomes hazardous when it is considered "dense" and obscures visibility to 1/4 mile or less. This results in decreased response time for operators of motor vehicles, especially at higher speeds. Motorists should adjust driving speed accordingly, while using low-beam headlights. |
