In this blog post, we will explain everything you need to know about the blizzard warning in Iowa. It included expected snowfall, the potential dangers, and safety precautions. Read on to ensure you're fully prepared for the storm.

What is a Blizzard Warning?

A blizzard warning is issued when the conditions for a blizzard are expected to occur. These include frequent gusts of wind at or above 35 mph combined with falling or blowing snow. These conditions can reduce visibility to less than 1/4 mile for at least three hours, making travel extremely dangerous.

Blizzards often cause whiteout conditions, making it impossible to see the road or navigate. The NWS has issued this warning because blizzard conditions are expected to hit Northwest Iowa on Wednesday, with the potential for significant snowfall and dangerously high winds.

What to Expect in the Blizzard Warning Area

The NWS warns that total snow accumulations could range from 4 to 9 inches, with isolated areas possibly receiving up to 12 inches. The storm will bring strong winds gusting as high as 60 mph, leading to widespread blowing snow and reduced visibility.

Heavy snow and high winds could make travel difficult, if not impossible. The storm is expected to disrupt the Wednesday morning and evening commutes, so plan if you must travel.

How the Blizzard Could Impact Travel

The blizzard warning also means that travel could be hazardous, if not impossible. Blowing snow will likely reduce visibility significantly, especially on highways. If you must drive, the National Weather Service strongly advises you to restrict travel to emergencies only. If you get stranded, it’s important to have a winter survival kit. If you become stuck, remember to stay in your vehicle and call for help.

Strong winds during the blizzard could also damage trees and power lines, leading to power outages in some areas. Therefore, it’s important to be prepared for the possibility of losing electricity.

Safety Tips During a Blizzard

If you are caught in a blizzard warning area, here are some essential safety tips:

Stay Indoors: The safest option during a blizzard is to stay home. Avoid unnecessary travel, especially in areas with heavy snow and poor visibility.
Check the Latest Road Conditions: Before heading out, always check the latest road conditions. You can do this by calling 5-1-1 for your state’s road updates.
Wear Layers and Keep Warm: If you must go outside, wear multiple layers of clothing to stay warm. Cover your face and hands, as frostbite can occur quickly in cold conditions.
Use Your Vehicle for Shelter: If you get stuck, stay inside your car. Running your car for heat is okay, but ensure the exhaust pipe is clear of snow to avoid carbon monoxide poisoning.
Prepare a Winter Survival Kit: Keep a survival kit in your car with essential items like food and water, such as a flashlight, extra clothing, and a first-aid kit. This will help you in case of an emergency

Additional Weather Alerts for Iowa

The blizzard warning is not the only significant weather event happening in Iowa. There is also a severe thunderstorm threat. On Tuesday night and Wednesday, isolated thunderstorms could bring large hail and high winds. There is even a chance of tornadoes. If you live in the affected areas, stay updated on the weather and be prepared for changing conditions.

In addition to the blizzard warning, a red flag warning was issued for much of Iowa on March 17, 2025, due to high winds, low humidity, and dry conditions. These conditions increase the risk of fires, especially in areas with strong winds. Be mindful of this risk and avoid outdoor burning.

What Else Can You Expect from the Weather?

The storm will move west to east across Iowa, with more than a 75% chance of snow accumulations of 4 inches or more in areas around Storm Lake and Algona. The Des Moines area is less likely to receive significant snow, with only a 10% likelihood of reaching 4 inches or more.

It’s important to note that the areas to the east of Iowa, such as Davenport and Burlington, will likely miss the snowfall entirely.

With the potential for heavy snow, powerful winds, and dangerous travel conditions, it’s crucial to be prepared.
