A Blizzard Warning is in effect until 6:00 PM EST on February 23, bringing heavy snow accumulations of 9 to 13 inches, blowing snow, and wind gusts up to 45 mph. Conditions are extremely dangerous for driving throughout the day, with the morning hours being the most severe.
- 01 Active Blizzard Warning in effect from early morning until 6:00 PM EST, issued by NWS Mount Holly NJ with Extreme severity
- 02 Heavy snow falling at rates of 1 to 3 inches per hour through the morning hours, with total accumulations of 9 to 13 inches expected
- 03 Wind gusts up to 45 mph with sustained winds of 17 to 29 mph, creating dangerous crosswind and high-profile vehicle conditions
- 04 Blowing snow expected to significantly reduce visibility throughout the entire day and into the evening hours
- 05 Temperatures hovering between 29–34°F all day with wind chill values as low as 14°F, keeping roads icy and compacted snow slippery
- 06 Precipitation probability is 80–96% from 6 AM through 10 AM, indicating near-certain heavy snowfall during the morning commute
- 07 NWS instruction explicitly states travel should be restricted to emergencies only
- 08 Even after the Blizzard Warning expires at 6 PM, blowing snow and freezing temperatures (dropping to 20°F overnight) will leave roads hazardous well into the evening
Travel should be avoided entirely today unless it is a life-threatening emergency. If driving is absolutely unavoidable, the least dangerous morning window would be after 11:00 AM – 12:00 PM EST, when snowfall rates begin to decrease and wind speeds slightly ease (though blizzard conditions may still persist). For the evening, the safest possible window would be after 7:00 PM – 8:00 PM EST, after the Blizzard Warning has expired and active precipitation has largely ended — however, expect untreated, snow-covered, and icy roads, continued blowing snow, poor visibility, and temperatures near or below freezing. Always carry a winter survival kit if you must travel.
