New Orleans, La. – Dangerously cold wind chills continue to impact parts of southeast Louisiana and southern Mississippi, prompting ongoing Cold Weather Advisories through Tuesday morning, with another round of cold conditions expected early Wednesday.
According to the National Weather Service office in New Orleans, wind chills between 15 and 25 degrees are affecting a wide portion of southeast Louisiana, creating hazardous conditions for anyone exposed to the cold for extended periods.
Areas Currently Under Cold Weather Advisories
The advisory in effect through 9 a.m. CST Tuesday covers much of southeast Louisiana, including Baton Rouge, St. Tammany, Tangipahoa, Livingston, Pointe Coupee, East Feliciana, West Feliciana, and Washington parishes. In southern Mississippi, impacted counties include Amite, Pike, Walthall, Wilkinson, Pearl River, and Hancock.
Forecasters note that persistent north winds are driving temperatures down, making conditions feel significantly colder than actual air temperatures, especially during the overnight and early morning hours.
Another Cold Round Expected Tuesday Night Into Wednesday
Additional Cold Weather Advisories have been issued for southeast St. Tammany Parish and coastal Mississippi counties, including Harrison, Jackson, and Hancock, beginning at midnight Tuesday night and lasting until 9 a.m. CST Wednesday.
During this period, wind chills are expected to drop to around 25 degrees, renewing health concerns even after a brief period of slightly improved conditions during the day Tuesday.
Meteorologists caution that repeated cold exposures across consecutive mornings can compound risks, particularly for vulnerable populations.
Health Risks From Prolonged Cold Exposure
Cold wind chills at these levels significantly increase the risk of hypothermia and cold-related illnesses, especially for young children, older adults, outdoor workers, and individuals without reliable heating or adequate shelter.
Health officials warn that hypothermia can occur even when temperatures are above freezing if wind speeds are strong and exposure lasts long enough. Symptoms may include uncontrollable shivering, confusion, slowed speech, and fatigue. In severe cases, hypothermia can become life-threatening.
Even short outdoor trips during the coldest overnight and early morning hours may be dangerous without proper protective clothing.
Safety Guidance for Residents
Officials urge residents across the affected areas to take extra precautions during this extended cold stretch.
Recommended safety measures include:
- Limiting time outdoors, especially overnight and early mornings
- Wearing multiple warm layers, including hats, gloves, and insulated footwear
- Bringing pets indoors or ensuring they have adequate warmth
- Checking on elderly neighbors, family members, and anyone without dependable heating
- Using space heaters safely and keeping them away from flammable materials
Authorities also stress that generators, grills, and fuel-burning heaters should never be used indoors, as improper use can lead to carbon monoxide poisoning.
Outlook for the Rest of the Week
Temperatures are expected to slowly moderate later Wednesday morning as winds weaken and daytime heating improves. However, officials caution that cold conditions remain a concern across the region, particularly during nighttime hours.
Residents are encouraged to continue monitoring local forecasts and advisories, as additional cold alerts may be issued if conditions change.
Conclusion
With dangerous wind chills lingering across southeast Louisiana and southern Mississippi, residents are urged to remain cautious through midweek. Taking preventive steps now can help reduce health risks as the region navigates another round of unseasonably cold weather.
