![]() |
Moderate |
Open burning is usually safe with the proper precautions. |
![]() |

![]() |
Very High | Open burning should not be attempted. Open fires can quickly escape and are very difficult to control, even for experienced fire fighters. Conditions exceed minimum criteria for a Red Flag Warning in most cases. |
![]() |
Severe | Very strong winds, well in excess of Red Flag Criteria combined with moderate to low humidity. Fires will spread very quickly with spot fires common. Fire control is extremely difficult due to very strong winds. |
