An historic January storm dumped more deep snow along the U.S. Gulf Coast on Wednesday after bringing Houston and New Orleans to a near standstill over the past two days and burying parts of Florida's Panhandle with accumulations more typical of Chicago.

Florida experienced unprecedented snowfall this week, breaking its all-time record with 9.8 inches in Milton, surpassing the previous 1954 record of 4 inches.

An Extreme Cold Warning is in effect until 10 a.m. Wednesday, as wind chills could drop to as low as 3 degrees in some spots. Frostbite and hypothermia will occur if unprotected skin is exposed to these temperatures. An extended period of freezing temperatures could cause ruptured water pipes.
