Weather warning for fog in 6 Massachusetts counties until early Monday morning

At 4:27 p.m. on Sunday, the National Weather Service issued a report predicting fog for southern Worcester and Norfolk, Bristol, Plymouth, Barnstable, Dukes and Nantucket counties until 5 a.m. Monday.

“Very humid conditions will continue through the night and will result in more areas of fog. Dense fog is expected in places, reducing visibility to a quarter mile or less in places. Travelers should be prepared for visibility to deteriorate quickly. Slow down and allow more time to reach your destination safely,” the weather service said.

Weather service advice on navigation in fog

If you must venture outside in foggy weather, follow these safety tips from the weather service:

Reduce your speed:

• Drive slower and allow more time for your journey to reach your destination safely.

Visibility priority:

• Make sure your vehicle is visible to others by turning on your low beam headlights, which will also activate your tail lights. Turn on your fog lights, if you have them.

Avoid high beam:

• Avoid using your high beams as they will blind you and make it more difficult to see what is on the road ahead.

Maintain a safe distance:

• Maintain a generous following distance to compensate for abrupt stops or changing traffic patterns.

Stay on your lane:

• To ensure you stay in the correct lane, follow the lane markings.

Zero visibility protocol:

• If visibility is almost zero due to thick fog, turn on your hazard lights and find a safe place, such as the parking lot of a nearby business, to stop.

Limited parking:

• If parking is not available, pull your vehicle as far to the side of the road as possible. Once you stop, turn off all lights except the hazard lights, apply the emergency brake, and release the brake pedal to ensure your tail lights are off. This will reduce the risk of other drivers colliding with your stationary vehicle.

If you follow the weather service’s recommendations, you can navigate more safely in fog, reduce the risk of accidents and increase your well-being.
