Mobile, AL – Imagine leaving the Gulf Coast for Thanksgiving, heading north on Interstate 65 toward Tennessee when a sudden burst of heavy snow develops farther along the trip. Within moments, vehicles become difficult to see, brake lights fade into blowing snow and a routine holiday drive turns dangerous.
Although snow squalls are exceptionally rare along the Gulf Coast, travelers heading inland should understand this winter hazard before Thanksgiving on Thursday, Nov. 26.
According to the National Weather Service NWS , snow squalls are brief, intense bursts of snowfall that can produce gusty winds, near zero visibility and rapidly deteriorating road conditions. Sometimes informally called "micro blizzards," they can create dangerous driving conditions within minutes.
Gulf Coast Highways Where Travel Awareness Matters Interstate 10 connects Houston, TX; Lake Charles, LA; New Orleans, LA; Biloxi, MS; Mobile, AL; and Pensacola, FL, making it a major holiday travel corridor.
Interstate 55 through southern Mississippi, Interstate 65 north of Mobile, and Interstate 49 through Louisiana connect Gulf Coast motorists with inland destinations where winter weather becomes more plausible.
Drivers leaving Harris County, TX; Orleans Parish, LA; Harrison County, MS; Mobile County, AL; and Escambia County, FL, should review conditions along their entire route.
Near the coast, heavy rain, thunderstorms and fog are generally more relevant visibility hazards than snow squalls.
Farther north, freezing rain, sleet, snow and icy bridges can become concerns when cold weather develops.
What Happens When a Snow Squall Warning Is Issued? The NWS issues Snow Squall Warnings when dangerous snow squalls are occurring or imminent.
Warnings typically last 30 to 60 minutes and may trigger Wireless Emergency Alerts on compatible phones.
Sudden whiteouts at highway speeds can increase the risk of multivehicle crashes, particularly when drivers brake abruptly or follow too closely.
What Thanksgiving Travelers Should Do If a Snow Squall Warning affects a planned route, delay travel until conditions improve .
Drivers already traveling should slow gradually, increase following distance, use low beam headlights and avoid sudden braking.
If visibility becomes dangerously poor, safely exit the highway when possible rather than stopping in an active travel lane.
Before departing, check DriveTexas , Louisiana 511 , Mississippi 511 , ALGO Traffic and FL511 for road conditions.
Official forecasts and warnings are available from the National Weather Service , including local offices serving coastal communities and inland destinations.
This is a Thanksgiving travel preparedness reminder, not a prediction that snow squalls will strike the Gulf Coast during the holiday. For coastal families traveling north, checking conditions beyond their home state may be the most important winter safety precaution.
