TRAVEL ALERT: Dense Fog Advisory Issued For Upper Dublin

Dense fog continues to hang over the Delaware Valley, bringing hazardous driving conditions to communities in Montgomery, Chester, Delaware, and Bucks Counties.

An advisory was issued by the National Weather Service (NWS) at 1:18 a.m. Wednesday morning and will be in effect until 10 a.m.

Visibility will be less than a quarter of a mile.

Over a period of 17 days, since December 13, the NWS has issued seven dense fog advisories.

Montgomery County Fire and Rescue Services in Virginia shared these safety tips for driving in fog:

• Drive with lights on low beam. High beams will only be reflected back off the fog and actually impair visibility even more.
• Reduce your speed -- and watch your speedometer. Fog creates a visual illusion of slow motion when you may actually be speeding.
• Listen for traffic you cannot see. Open your window a little, to hear better.
• Use wipers and defrosters as necessary for maximum visibility.
• Use the right edge of the road or painted road markings as a guide.
• Be patient. Do not pass lines of traffic.
• Do not stop on a freeway or heavily traveled road. If your car stalls or becomes disabled, turn your vehicle’s lights off, and take your foot off of the brake pedal. People tend to follow tail lights when driving in fog. Move away from the vehicle to avoid injury.
