Tourists planning to visit Northern Minnesota cities including Duluth, Cloquet, Two Harbors, and Superior this week should prepare for hazardous weather conditions. According to the National Weather Service (NWS) Duluth, a strong system of heavy rainfall and thunderstorms is expected to move into the region starting Thursday evening, July 11, with intense impacts forecasted into Friday, July 12.
The system is predicted to bring not only thunderstorms and lightning but also flash flooding, high humidity, and dangerous driving conditions. Travelers and tourism-related businesses are advised to monitor local updates closely and adjust plans as necessary.
Weather Forecast Overview: What’s Coming and When
Meteorologists at the NWS forecast scattered thunderstorms beginning Thursday night, intensifying throughout the early hours of Friday. Daytime temperatures are expected to range from 77°F to 87°F, with increased humidity making conditions feel warmer and more uncomfortable, particularly inland. Although areas close to Lake Superior may experience slightly cooler temperatures, the storm’s effects will be widespread across the Arrowhead region.
The National Oceanic and Atmospheric Administration (NOAA) warns of isolated flash flooding due to downpours, especially in low-lying and poor drainage areas. In these regions, travel may become temporarily impossible due to road washouts or water accumulation.
Driving in Severe Weather: What Road Travelers Should Know
Those heading to popular regional destinations like Gooseberry Falls State Park, Canal Park in Duluth, or scenic routes along Highway 61 should brace for road hazards. Torrential rains could lead to poor visibility, hydroplaning risks, and road closures near rivers, creeks, and underpasses.
The Minnesota Department of Transportation (MnDOT) urges drivers to:
- Avoid flooded roads and never attempt to drive through standing water.
- Check 511mn.org for real-time road condition reports.
- Keep emergency kits in vehicles including drinking water, power banks, first-aid, and flashlights.
- Map out alternate routes in case of roadblocks or detours.
Drivers are advised to reduce speeds, turn on headlights, and increase following distances to improve safety on slick roads.
Duluth International Airport (DLH) and Flight Advisory
Air travelers flying in or out of Duluth International Airport on Thursday evening or Friday should be prepared for potential flight delays or cancellations due to lightning, wind shear, or low visibility. Airlines often adjust flight paths or delay departures as a safety measure during severe weather systems.
The Federal Aviation Administration (FAA) notes that weather-related delays can impact air traffic regionally—even if your specific flight is not affected, the inbound aircraft may face delays. Travelers should:
- Enroll in real-time flight alerts through their airline.
- Monitor flyduluth.com and airline apps for gate updates and departure time changes.
- Plan for additional time at the airport and consider flexible itineraries.
Local Transport, Tourism & Attractions Impact
Public transportation options including Duluth Transit Authority (DTA) buses and shuttle services may experience route suspensions or delays due to flooded intersections or downed trees. Ride-share services such as Uber and Lyft may have longer wait times or surge pricing due to increased demand during inclement weather.
Visitors planning to explore North Shore trails, Superior hiking routes, or other outdoor attractions around Lake Superior should consider shifting their itineraries toward indoor activities. Museums like the Lake Superior Maritime Visitor Center, the Glensheen Mansion, and indoor shopping centers remain good alternatives during weather disruptions.
Hotel and Accommodation Precautions
For those staying at regional accommodations—from lakeside inns to chain hotels like Holiday Inn Duluth, AmericInn Cloquet, and Country Inn & Suites Superior—it’s advisable to:
- Inquire about backup power availability and emergency protocols.
- Prepare an in-room emergency kit with bottled water, snacks, essential medications, and contact numbers.
- Ask about cancellation flexibility or rescheduling policies in case weather prevents check-in or safe travel.
Hotels are also advising guests to avoid walking or driving during peak storm hours and instead wait until NWS issues an “all-clear.”
Travel Smart: Safety Tips During Northern Minnesota Storms
Whether you’re arriving for scenic hikes, lakeside relaxation, or a North Shore road trip, storm preparedness is key to a safe and enjoyable visit. Here’s what tourism authorities recommend:
- Follow NWS Duluth on social media for localized alerts.
- Download the Minnesota Emergency Alert app for real-time notifications.
- Avoid recreational boating or water activities during thunderstorm warnings.
- Keep your gas tank at least half full in case of long detours or closures.
Final Word: Stay Flexible and Weather-Aware
Minnesota’s unpredictable summer storms can quickly shift from mild to severe. While weather disruptions may dampen outdoor plans in Duluth, Cloquet, Two Harbors, and Superior, staying alert, flexible, and informed can help travelers make the most of their visit. With proper planning and a backup itinerary, Northern Minnesota remains a rewarding destination—rain or shine.
