The National Weather Service in New Orleans has issued multiple winter weather statements to help prepare south Louisiana for forecast, cold temperatures ahead. 

As of Sunday evening, they issued a "Hard Freeze Warning," a "Freeze Warning," and a "Wind Chill Advisory."

Here is a breakdown of each:

HARD FREEZE WARNING & FREEZE WARNING

A Freeze Warning remains in effect for the entire area from midnight tonight to 9:00 a.m.. Monday.

Hard Freeze warning remains in effect from 6:00 p.m.. Monday until 9:00 a.m.. Tuesday.

Timing: Temperatures will drop below freezing after midnight and remain below freezing through mid-morning Monday. After modest warming Monday, temperatures will fall below freezing Monday evening and remain below freezing through mid-morning Tuesday.

Temperatures: Minimum temperatures in the mid to lower-20s are forecast for Monday morning. Minimum temperatures in the teens to mid-20s are forecast for Monday night and Tuesday morning.

Duration: Freezing temperatures are expected for a period of 2 to 6 hours Sunday night. Freezing temperatures are expected for a period of 10 to 14 hours Monday night with a duration of 7 to 12 hours below 26 degrees.

Impacts: Hazardous, life threatening conditions for persons, livestock and pets. Property loss is possible from frozen pipes and plumbing. Horticultural and agricultural losses can be significant without proper mitigation measures.

WIND CHILL ADVISORY

A Wind Chill Advisory remains in effect for the entire area from midnight until 6:00 a.mm. Monday.

Timing: From midnight through Monday morning.

Wind chills: Winds chills will mainly be in the teens late tonight and early Monday morning.

Impacts: A wind chill advisory means that very cold air and strong winds will combine to generate low wind chills. This will result in frost bite and lead to hypothermia if precautions are not taken. 

Precautionary/preparedness tips...

  • Be particularly careful with portable heaters; there is danger of fire or poisonous fumes.
  • Stay inside.
  • If you must go outside, dress in layers.
  • Wear a hat; almost 20 percent of body-heat-loss is through the head.
  • Wear gloves. Cover any exposed skin.
  • Bring temperature sensitive plants indoors or cover them with an old sheet/blanket.
  • Remember your pets. If you're cold, then they're cold.
