A squall line of thunderstorms moves west to east with our main threats of damaging straight-line winds of 50-60 mph and lightning. We cannot rule out an isolated tornado threat either.

A wind advisory has been issued. In addition to the damaging wind, lightning and isolated tornadoes are possible. Timing for Jacksonville peaks between noon and 4 p.m.

Here are some safety tips from the Weather Channel on how to drive through severe weather.

Note: In Florida, it is illegal to drive with your hazard lights

Another Note: We're going to say this again. It's illegal to drive with your hazard lights on. DON'T DO IT.

Rain

  • Change windshield wiper blades at least twice a year or every 6,000 miles.
    Nothing is more important when driving in rain than having a good set of wiper blades.
  • Spray a good rain repellant on your windshield before driving to help provide a clear view.
  • Check your tires regularly for visible signs of wear or damage.
  • Don't use cruise control or overdrive on wet roads.


Flash floods

  • "Turnaround, Don't drown”; if you don't know the depth of water before crossing.
  • Abandon stalled vehicles immediately and seek higher ground.


Tornadoes

  • Never try and out drive a Tornado.
  • Leave your vehicle, and go to a concrete shelter.
  • If there is no shelter nearby, lie flat in the nearest ditch with your hands shielding your head.
  • Be alert for rapidly rising waters in the ditch.
  • Do not seek refuge in an overpass where winds can be magnified.
