Louisiana: Hour-by-Hour Timeline and Final Meteorologist Warnings for Historic Snowstorm

As Louisiana braces for a rare and potentially historic snowstorm, meteorologists across the state are issuing final warnings, refining snowfall predictions, and providing an hour-by-hour timeline for what to expect. The incoming winter storm is expected to bring significant snow and ice accumulations, disruptive winds, and sub-freezing temperatures that will impact the region for several days. Here’s the latest update on what you need to know.

When Will It Start?

• Precipitation Begins: Light rain and sleet will develop late Monday night around midnight.
• Snowfall Commences: By the early hours of Tuesday morning, precipitation will transition to snow as temperatures drop below freezing. Snow accumulations are expected to intensify through the morning hours.

Snowfall Totals and Predictions

Acadiana and South Louisiana

• Rob Perillo (KATC): 4-6 inches of snow, with potential localized totals of 8-10 inches along and south of I-10.

• Chris Cozart (KLFY): 4-8 inches expected across much of Acadiana, with some areas possibly seeing over 10 inches. Strong winds could result in blizzard-like conditions and snow drifts of 1-2 feet.

• Trevor Sonnier (KLFY): Latest high-resolution models suggest 5-12 inches in some areas, particularly near and south of I-10.

New Orleans and Southeast Louisiana

• Zack Fradella (FOX 8): 5-8 inches of snow, with areas of higher accumulation possible. Travel will be nearly impossible, and tree branches could snap under the snow's weight.

• Payton Malone (WWLTV): 3-7 inches, with isolated spots exceeding 8 inches if the system overperforms.

Travel Warnings

• Road Conditions: Elevated roads and bridges will ice over first, followed by surface roads as snow intensifies. Travel is expected to become dangerous and impassable by early Tuesday morning, potentially lasting through Thursday.

• Stay Home: I-10 and other major highways are likely to shut down. Plan to shelter in place for at least 48 hours as road conditions are not expected to improve until temperatures rise on Thursday.

Dangerous Cold

• Prolonged Sub-Freezing Temperatures:
  • Acadiana is expected to remain below freezing for up to 60 hours, with overnight lows dropping into the teens.
  • Wind chills could dip into the single digits, creating dangerous conditions for anyone exposed to the cold.

• Protect Pipes, Pets, and People:
  • Wrap outdoor pipes and allow indoor faucets to drip.
  • Bring pets inside and ensure they have a warm place to stay.
  • Check on elderly neighbors and ensure your home is equipped with blankets, heaters, and other essentials.

Timeline of the Storm

• Monday Night: Light precipitation begins around midnight as rain or sleet.
• Early Tuesday Morning: Precipitation transitions to snow, with accumulations beginning by sunrise.
• Tuesday Morning to Afternoon: Snowfall intensifies, with heavy bands of snow leading to rapid accumulations of up to an inch per hour.
• Tuesday Evening: Snow tapers off, but hazardous conditions will persist as temperatures remain below freezing.
• Wednesday and Beyond: Any partial melting during the day Wednesday will refreeze overnight, keeping roads icy into Thursday morning.

Historic Implications

This storm is being compared to the Gulf Coast Snowstorm of 1895, one of the most significant winter events in Louisiana’s history.

With widespread snowfall, prolonged freezing temperatures, and strong winds, this event has the potential to disrupt daily life for days.

Stay Safe and Informed

• Preparation: Ensure you have enough food, water, and supplies to last 2-3 days.
• Stay Updated: Follow your local meteorologists and news outlets for real-time updates.
• Avoid Travel: Roads will be treacherous. Stay home and avoid unnecessary risks.

While snow can be exciting and tempting to get out and capture with our smartphones, the impacts of this storm are serious. Louisiana residents should take this storm as an opportunity to prioritize safety and preparation. Stay warm, stay safe, and enjoy the snow from the comfort of your home if possible.
