Surface moisture has helped generate morning fog along the Gulf Coast, reducing visibility in many locations. A Dense Fog Advisory is in effect for our entire viewing area until 9pm. What causes it, and why is it so hard to see through fog? Well, think of fog as a cloud trapped right at the surface. It develops when the outdoor temperature drops to the dew point, and invisible water vapor in the air condenses to form suspended water droplets.
It can narrow visibility to one-quarter of a mile or less, creating dangerous driving conditions. When their is blinding fog around, the safest thing to do as far as driving, is don't do it.
If you absolutely have to drive, here are some things to remember.
*Use the low beam. High beams only reflected back off the fog.
*Slow down, fog can make it seem like your driving in slow motion when actually you might be speeding.
*Drive on the right side of the road or painted road markings as a guide.
* Keep a safe distance between your car and the car in front of you in case they come to a sudden stop.
* Don't stop on busy roads. If your car stalls or you just can't see, pull way over turn off your lights, and take your foot off the brakes. People tend to follow tail lights when driving in fog.
