Wednesday: Fog Risk

1: Limited

Patchy Fog or Freezing Fog could lead to lowered visibilities leading to dangerous driving conditions.

What is this based on?

We base this risk on local weather office fog and visibility forecasts.

Risk levels

Fog Risk

risk level name	risk level description
1:Limited	Patchy Fog or Freezing Fog could lead to lowered visibilities leading to dangerous driving conditions.
2:Elevated	Areas of Fog or Freezing Fog will reduce visibilities, creating dangerous driving conditions. If Freezing Fog develops, it could lead to a light glaze of ice, resulting in slippery conditions.
3:Significant	Widespread Fog or Freezing Fog will significantly reduce visibilities, creating dangerous driving conditions. If Freezing Fog develops, a coating of ice will result in slippery conditions.

Wednesday: 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.

2:Elevated	Numerous thunderstorms with dangerous cloud-to-ground lightning expected.
3:Significant	Widespread thunderstorms with dangerous cloud-to-ground lightning expected.

Wednesday: Snow/Sleet Risk

3: Significant

Significant snow and/or sleet accumulations are likely to result in widespread hazardous travel conditions.

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	Light snow and/or sleet accumulations are likely to result in locally slick travel conditions, especially on bridges, overpasses, and untreated secondary roads.
2:Elevated	Moderate snow and/or sleet accumulations are likely to result in slick travel conditions.
3:Significant	Significant snow and/or sleet accumulations are likely to result in widespread hazardous travel conditions.
4:Extreme	Extreme snow and/or sleet accumulations are likely to result in widespread, prolonged travel disruptions. Travel may be impossible in some areas The weight of the heavy snowpack may stress some roofs. This is an extremely dangerous situation.

Thursday: Snow/Sleet Risk

1: Limited

Monday: Extreme Heat Risk

1: Limited

Heat exhaustion possible with prolonged exposure.

What is this based on?

We base this risk on local weather office temperature and/or heat index forecasts.

Monday: Fire Weather Risk

1: Limited

Low humidity and breezy conditions will result in an increased danger of fires getting out of control.

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	Low humidity and breezy conditions will result in an increased danger of fires getting out of control.
2:Elevated	Low humidity and windy conditions will create dangerous fire weather conditions. Fires could escape containment and be difficult to control. In some cases, this could also signify that additional fire starts are possible with scattered dry thunderstorms.
3:Significant	Low humidity and high winds will create significant fire weather conditions. Fires could escape containment and be very difficult to control.
4:Extreme	Very low humidity and high winds will create extremely volatile fire weather conditions Fires could spread very quickly with long-range spot fires common. Fire containment and control efforts may be extremely difficult or impossible. This is an extremely dangerous situation.

Tuesday: Fire Weather Risk

2: Elevated

Low humidity and windy conditions will create dangerous fire weather conditions. Fires could escape containment and be difficult to control. In some cases, this could also signify that additional fire starts are possible with scattered dry thunderstorms.

What is this based on?

Tuesday: Wind Risk

1: Limited

Breezy conditions could blow around unsecured outdoor objects and result in difficult driving conditions for some high-profile vehicles. Localized blowing dust or snow is possible.

What is this based on?

We base this risk on local weather office wind speed/gust forecasts.

1:Limited	Breezy conditions could blow around unsecured outdoor objects and result in difficult driving conditions for some high-profile vehicles. Localized blowing dust or snow is possible.
2:Elevated	Windy conditions could blow around unsecured outdoor objects and result in hazardous driving conditions for high-profile vehicles. Blowing dust or snow will likely reduce visibility, making driving hazardous in some spots.
3:Significant	Very windy conditions could result in damage to trees, powerlines, and outbuildings, resulting in power outages and/or blocked roads. Travel could be very dangerous for high-profile vehicles. Blowing dust or snow may result in very low visibilities, making driving very difficult in some spots.
4:Extreme	Extremely windy conditions could result in widespread damage to trees, powerlines, roofs, and outbuildings. Widespread power outages and blocked roads are possible. Blowing dust or snow may result in visibilities near zero. Travel may be extremely difficult. This is an extremely dangerous situation.
