Gulf Coast Hurricane Tracker

A single source reference on tropical weather predictions. With a traditional focus on the upper Texas and Louisiana Gulf Coast we've maintained links to track all Atlantic Basin, Caribbean and eastern Pacific storm systems. We are now expanding our view to tropical storms throughout the world intending to be a comprehensive global storm tracking resource.

Arctic cold in the deep south

A winter weather advisory has been issued for North and Central Georgia for Thursday from noon until around midnight. Light snow will provide anywhere from a light dusting to about 1/4" accumulation in most areas. We have a 60% chance of flurries or snow showers.

The problem is that the temperaure is actually expected to warm up just enough that light drizzle is predicted for the morning. Then once everything is good a wet, the temperatures will drop and change the rain to sleet or slow. This is a good recipe for ice.

Atlanta road crews are already salting and sanding some roadways where the potential for ice formation is high. Some school districts in the northern regions are already planning for early release to get everyone home before teh bad weather starts.

The entire Southland from Georgia to central Texas has been trapped in unusually cold weatehr all week. Driving from Austin, TX Monday, the highest temperature I noticed during the entire trip was 35 degrees in Dallas. Fron then on as I drove east the temperature steadily dropped eventually reaching the lower 20's by the time I got into Atlanta. We have had a low temperature of 17 degrees F for the past 4 mornings.

I thought I lived in the south?!?!

Hard freeze warnings are in place for southern Geaorgia and northern Florida. Wnter weather is expected from Pennsylvania all the way to southern Mississippi and west to Houston.
