The National Weather Service has issued a freeze warning and a fire warning, called a red flag warning, for metro Atlanta.

The red flag warning is in effect until 7 p.m. March 3 due to low humidity and strong winds in north and central Georgia.

“A Red Flag Warning means that critical fire weather conditions are either occurring, or will occur within 24 hours,” the National Weather Service says. “Please refer to the local burn permitting authorities on whether you may burn outdoors. If you do burn outside, use extreme caution.”

The freeze warning starts at midnight on March 4 and lasts until 9 a.m. Saturday. Temperatures will drop into the upper 20’s.

“A Freeze Warning means sub-freezing temperatures are imminent or highly likely,” the National Weather Service says. “These conditions will kill crops and other sensitive vegetation.”

The National Weather Service says dry conditions will likely persist through the weekend. There’s a chance of thunderstorms on Tuesday.
