Severe Weather Alert: What You Need to Know About Friday’s Storms in Louisiana and Mississippi
IMPORTANT: This article covers active weather warnings for Friday. Conditions can change quickly. Always check the latest updates from your local weather team.
What’s Happening Right Now?
Severe storms are moving across southeast Louisiana and south Mississippi this Friday afternoon. The National Weather Service has issued two important warnings that are active right now:
Active Weather Warnings
| Warning Type | Areas Affected | Expires |
|---|---|---|
| Flash Flood Warning | Northeastern Jefferson Parish, Orleans Parish, Plaquemines Parish | 6:15 p.m. |
| Severe Thunderstorm Warning | New Orleans, Jefferson Parish, St. Bernard Parish, St. Tammany Parish, Plaquemines Parish, Hancock County, MS | 4:30 p.m. |
ELI5 Explanation: A Warning means dangerous weather is happening right now or is about to happen very soon. Take action immediately! A Watch (not issued here) means conditions are favorable for bad weather—stay alert.
How Bad Could It Get? (The "Risk Levels" Explained)
Weather experts use a 1-to-5 scale to describe how likely severe storms are. Today sits at Level 2 (Slight Risk).
Today’s Threat Levels
| Risk Level | Name | What It Means for You |
|---|---|---|
| Level 1 | Marginal Risk | Isolated severe storms possible. Flooding risk today. |
| Level 2 | Slight Risk | Severe weather risk today. Scattered severe storms expected. |
| Level 3 | Enhanced Risk | Numerous severe storms likely. |
| Level 4 | Moderate Risk | Widespread severe storms likely. |
| Level 5 | High Risk | Extreme, long-lived severe weather outbreak. |
KEY TAKEAWAY: Level 2 (Slight Risk) means isolated to scattered severe storms are expected. Not everyone will get hit, but some storms will be dangerous.
The Main Dangers Today
- Damaging Winds (Biggest threat): Gusts strong enough to snap trees and damage roofs.
- Flash Flooding (Low-end threat): Heavy rain in a short time can flood streets and low-lying areas.
- Note: A Level 1 Marginal Flood Risk is active for all of SE LA and S MS.
Why Are These Storms Forming? (The Simple Science)
You don’t need a meteorology degree to understand the setup. Think of it like a recipe:
- The Trigger (The "Lift"): An upper-level disturbance (a pocket of energy high in the sky) is teaming up with a cold front moving in at ground level. Together, they act like a giant vacuum, sucking warm, moist air upward to build storms.
- The Fuel (Instability): The air is "moderately to strongly unstable." Translation: The air near the ground is warm and humid, while the air above is cooler. This temperature difference lets storm clouds grow tall and strong quickly—like a hot air balloon rocketing upward.
Storm Timeline: When Will It Hit Your Neighborhood?
Storms won’t hit everywhere at once. They move in a line from north to south. Here is the hour-by-hour breakdown:
Phase 1: The Spark (4:00 PM – 6:00 PM)
- Where: South Mississippi & Northshore (St. Tammany, Washington Parishes).
- What: Individual strong to severe storms pop up first here.
Phase 2: The Main Line (6:00 PM – 8:00 PM)
- Where: New Orleans Metro & River Parishes (Jefferson, Orleans, St. Charles, St. John, Lafourche).
- What: Those individual storms merge into a solid line (squall line). This is when the highest wind risk arrives for the metro area.
Phase 3: The Fade Out (9:00 PM – 10:00 PM)
- Where: Bayou & Coastal Parishes (Terrebonne, Lafourche, Plaquemines, coastal Mississippi).
- What: The line pushes south toward the Gulf, weakening as it goes. The severe threat ends.
Your Safety Checklist: What To Do Right Now
STOP: If you are in a WARNING area (see table above), take these steps NOW.
- Get Inside: Move to a sturdy building. Avoid mobile homes and vehicles during high wind warnings.
- Stay Away from Windows: Go to an interior room on the lowest floor (bathroom, closet, hallway).
- Turn Around, Don’t Drown: NEVER drive through flooded roads. It takes only 12 inches of moving water to carry away a car. You cannot see if the road is washed out.
- Secure Loose Items: Bring in patio furniture, trash cans, trampolines—anything the wind could turn into a missile.
- Charge Devices: Plug in phones and backup batteries now in case power goes out.
- Have a Way to Get Alerts: Don’t rely on just one method.
- Wireless Emergency Alerts (WEA) on your phone (keep them ON).
- NOAA Weather Radio.
- WDSU First Warning Weather Team (TV/App/Social Media).
Summary: The Bottom Line
- Severe storms are active Friday afternoon/evening.
- Two warnings are live: Flash Flood (until 6:15 PM) & Severe T-Storm (until 4:30 PM, likely extended).
- Main Threats: Damaging straight-line winds (60+ mph) and localized flash flooding.
- Timing: Northshore/MS Coast 4-6 PM → Metro New Orleans 6-8 PM → Coast/Bayous 9-10 PM.
- Action: Stay indoors, avoid travel if possible, never drive through flood water, and keep alerts ON.
FAQ: Your Questions Answered
1. What is the difference between a "Watch" and a "Warning"?
A Watch means "Be Ready." Ingredients for bad weather are there. A Warning means "Take Action Now!" The bad weather is happening or imminent. We are in WARNINGS right now.
2. What does "Level 2 Slight Risk" actually mean for my house?
It means there is a ~15-30% chance of severe weather (1" hail, 58+ mph winds, or a tornado) within 25 miles of you. Most people won’t see damage, but some neighborhoods will. Prepare as if you might be that neighborhood.
3. The warning says "until 4:30 PM." Does that mean it’s over then?
Not necessarily. Warnings are often extended or re-issued as the storms move. The 4:30 PM expiration is just the initial estimate. Stay sheltered until an official "All Clear" is given for your specific parish.
4. Is a tornado possible today?
The main threat is damaging straight-line winds, not tornadoes. However, in any "Slight Risk" setup, a brief, spin-up tornado can happen along the leading edge of the storm line. Treat a Severe Thunderstorm Warning just like a Tornado Warning: go to your safe room immediately.
5. Where do I get the most reliable, second-by-second updates?
