Sunday: Lightning Risk

1: Limited

Isolated to scattered thunderstorms with dangerous cloud-to-ground lightning expected.

What is this based on?

We base this risk on local weather office thunderstorm forecasts.

Lightning Risk

risk level name	risk level description
1:Limited	Isolated to scattered thunderstorms with dangerous cloud-to-ground lightning expected.
2:Elevated	Numerous thunderstorms with dangerous cloud-to-ground lightning expected.
3:Significant	Widespread thunderstorms with dangerous cloud-to-ground lightning expected.

Sunday: Snow/Sleet Risk

1: Limited

Snow and/or sleet with less than 4 inches of accumulation expected. Be aware of locally hazardous travel conditions, especially on bridges, overpasses, and untreated or secondary roads.

What is this based on?

We base this risk on local weather office snow/sleet accumulation forecasts.

Snow/Sleet Risk

risk level name	risk level description
1:Limited	Snow and/or sleet with less than 4 inches of accumulation expected. Be aware of locally hazardous travel conditions, especially on bridges, overpasses, and untreated or secondary roads.
2:Elevated	Snow and/or sleet with 4 to 6.9 inches of accumulation expected. Be prepared to reduce travel speed for hazardous travel conditions.
3:Significant	Snow and/or sleet with 7 to 17.9 inches of accumulation expected. Plan for hazardous travel conditions. Avoid travel if possible.
4:Extreme	Snow and/or sleet accumulations of 18 inches or greater expected. Travel will be dangerous, and may be impossible. Avoid travel unless it is an emergency.

Monday: Fire Weather Risk

1: Limited

Open burning is usually safe with the proper precautions. Burning should be done in the early morning and late evening to avoid windier and drier conditions from midday through mid afternoon.

What is this based on?

We base this risk on local weather office forecasts of combined relative humidity, winds, and wind gusts.

Fire Weather Risk

risk level name	risk level description
1:Limited	Open burning is usually safe with the proper precautions. Burning should be done in the early morning and late evening to avoid windier and drier conditions from midday through mid afternoon.
2:Elevated	Any open burning is discouraged due to windy conditions and lower humidity. Fires can escape control more easily and be difficult to contain.
3:Significant	Open burning should not be attempted. High winds and extended dry periods will produce extreme burning conditions. Open fires can quickly escape and are very difficult to control, even for experienced fire fighters. Conditions will exceed minimum Red Flag Criteria in most cases.
4:Extreme	Very strong winds, combined with low humidity, will create extremely volatile conditions well in excess of Red Flag Criteria. Fires will spread very quickly with spot fires common. Fire control will be extremely difficult.

Sunday: Frost/Freeze Risk

4: Extreme

Hard freeze expected with catastrophic damage to unprotected vegetation.

What is this based on?

We base this risk on local weather office temperature forecasts and other frost/freeze criteria.
