Quick Answer
Evacuation is not always necessary, but it's crucial to monitor the storm's severity and follow local authorities' instructions, as a coastal blizzard can bring catastrophic ocean surges and flooding.
Assessing the Storm’s Severity
When a coastal blizzard is forecasted, assess its potential impact on your location. Look for the storm’s wind speed, wave height, and ocean surge predictions. A Category 1 hurricane’s wind speed is 74-95 mph, while a Category 5 hurricane’s wind speed exceeds 157 mph. Ocean surges can reach up to 20 feet or more, depending on the storm’s category and the coastline’s geometry. Use the National Weather Service’s (NWS) storm surge watch/warning graphic to gauge the potential threat.
Preparing for the Worst
If you’re in a coastal area, prepare for the worst-case scenario by stockpiling emergency supplies, securing your home, and moving valuables to higher ground. Ensure your home’s doors and windows are sealed with plywood or shutters to prevent wind-borne debris and flooding. If you have a basement or storm cellar, use it as a safe room. If not, go to an interior room or hallway on the highest floor with no windows. Use a battery-powered radio and NOAA Weather Radio to stay informed about the storm’s progress and any evacuation orders.
Evacuation and Shelter
If local authorities order an evacuation, follow their instructions promptly. Move to a safe location, ideally inland and away from the coastline. If you’re unable to evacuate, seek shelter in an interior room or hallway on the highest floor with no windows. Stay away from windows, doors, and exterior walls. Use a battery-powered radio to monitor the storm’s progress and any updates from local authorities. If you’re trapped, call 911 or use a whistle to signal for help when the storm passes.
