Expected Severity and Timing of Strong Winds and Severe Storms

Wind Speeds and Gusts

High wind warnings are in effect as damaging winds and gusty conditions are expected. Sustained wind speeds of 40-50 mph are predicted, with peak gusts potentially reaching 70 mph. These high wind warnings are not to be taken lightly.

• 12 PM - 6 PM: Sustained winds 30-40 mph, gusts up to 55 mph.
• 6 PM - 12 AM: Sustained winds 40-50 mph, gusts up to 70 mph. This period represents the peak of the strong wind event.
• 12 AM - 6 AM: Sustained winds 30-40 mph, gradually diminishing gusts.

Such high wind speeds can cause significant damage:

• Downed power lines, leading to widespread power outages.
• Flying debris, posing a risk to property and people.
• Fallen trees, potentially causing structural damage and blocking roads.

Storm Type and Intensity

Severe thunderstorm warnings are also in effect. We are expecting a line of severe thunderstorms, potentially exhibiting characteristics of a derecho, bringing heavy rainfall, large hail, and the possibility of tornadoes.

• Rainfall totals could reach 2-4 inches in some areas, increasing the risk of flash flooding.
• There is a moderate risk of tornado formation within the severe thunderstorm complex.
• Areas along the I-90 corridor are expected to experience the most intense impacts.

Timing and Duration

The strong winds are expected to begin around midday, reaching peak intensity during the evening hours. The severe thunderstorms will follow closely behind the initial wind event.

• Strong winds: 12 PM - 6 AM (next day).
• Severe thunderstorms: 6 PM - 12 AM (next day).
• The entire event is anticipated to last approximately 18 hours.

Potential Impacts and Hazards

Wind Damage

The anticipated high wind speeds pose a significant threat of wind damage. This includes:

• Damage to roofs and siding on homes and businesses.
• Uprooted trees and damaged power lines.
• Broken windows and flying debris causing property damage.

To mitigate wind damage, secure all loose outdoor objects like patio furniture, garbage cans, and decorations.

Flooding and Storm Surge

With the heavy rainfall expected, flash flood potential is high, particularly in low-lying areas and near rivers and streams. There is a risk of significant river flooding in the coming days.

• Areas near the Mississippi River are at an increased risk of river flooding.
• Stay away from flooded areas; even shallow water can be dangerous. Never drive through floodwaters.
• If you live in a flood-prone area, have an evacuation plan ready.

Other Hazards

In addition to strong winds and flooding, other hazards are a concern:

• Large hail: Hailstones up to the size of golf balls are possible.
• Lightning strikes: Seek immediate shelter indoors during thunderstorms.
• Tornadoes: Monitor weather alerts closely and have a safe place identified to take shelter if a tornado warning is issued.

Safety Precautions and Preparedness

Before the Storm

A storm preparedness checklist is crucial for minimizing risks. Take the following steps:

• Secure loose objects around your property.
• Bring outdoor furniture and decorations inside.
• Charge all electronic devices.
• Fill your vehicle's gas tank.
• Create an emergency kit including water, food, first-aid supplies, and medications.

During the Storm

Stay informed and stay safe during the storm:

• Stay indoors in a sturdy structure, away from windows.
• Monitor weather reports closely via radio, TV, or a reliable weather app.
• If a tornado warning is issued, immediately seek shelter in a basement or interior room.
• Avoid contact with electrical equipment or water.

After the Storm

Post-storm safety is equally vital:

• Check for damage to your property and report it to the appropriate authorities.
• Avoid downed power lines and damaged areas.
• Be cautious of debris and hazardous materials.
• If your home has sustained damage, seek professional assistance.
